NBIA post-doc Jeroen Danon publishes Quantum Mechanics book
Cambrdige University Press has just published "Advanced Quantum Mechanics: A Practical Guide" by Yuli V. Nazarov and NBIA post-doc Jeroen Danon. Quoting from the publisher's description, this book is "An accessible introduction to advanced quantum theory, [it is] a graduate-level textbook [that] focuses on its practical applications rather than mathematical technicalities. It treats real-life examples, from topics ranging from quantum transport to nanotechnology, to equip students with a toolbox of theoretical techniques. Beginning with second quantization, the authors illustrate its use with different condensed matter physics examples. They then explain how to quantize classical fields, with a focus on the electromagnetic field, taking students from Maxwell's equations to photons, coherent states and absorption and emission of photons. Following this is a unique master-level presentation on dissipative quantum mechanics, before the textbook concludes with a short introduction to relativistic quantum mechanics, covering the Dirac equation and a relativistic second quantization formalism."
Jeroen Danon graduated from the Delft University of Technology, and after doing a postdoc at the Dahlem Center for Complex Quantum Systems (Freie Universität Berlin) he came to the NBIA in October 2012. He works in the fields of quantum transport and mesoscopic condensed matter physics. His main focus lies on problems closely related to experiment (e.g. spin/exchange qubits in quantum dots, induced superconductivity in nanowires), but he also works on more general theoretical problems such as dephasing and quantum corrections to electron transport in ferromagnetic metals.
Christine Hartmann receives Dirac Diploma and Best Student Award in Erice
At the recent International School of Subnuclear Physics "Reflections on the next step for the LHC" held in Erice, NBIA PhD-student Christine Hartmann received both this year's Paul A.M. Dirac Diploma and Best Student Award. The school ranged in topics from the latest experimental discoveries to hot theoretical developments, in the usual style of this unique and prestigious series of PhD-schools on particle physics. Speakers included Peter W. Higgs and Nobel Laureate Gerard 't Hooft, together with many distinguished lecturers on specialized topics.
Zohar Komargodski appointed Adjunct Professor at the NBIA
Zohar Komargodski of the Weizmann Institute in Rehovot, Israel, has been appointed Adjunct Professor of Theoretical Physics at the NBIA for a period of five years. Zohar Komargodski completed his PhD at the Weizmann Institute of Science just five years ago. Following a postdoctoral fellowship at the Institute for Advanced Studies, Princeton, he returned to a senior scientist position in the Weizmann Institute's Particle Physics and Astrophysics Department. His research is at the forefront of particle physics, quantum field theory and its links to more mathematical disciplines. He is particularly known for his work with Adam Schwimmer on the renormalization group flow in four-dimensional field theories, work that was included in the citation when last year he received the pretsigious "New Horizons in Physics" prize.
Chris Pethick elected Member of the American Academy of Arts and Sciences
NBIA Professor Chris Pethick is one of just two who have been elected Foreign Honorary Members of the Physics section of the American Academy of Arts and Sciences this year. In the citation, Chris Pethick is described as a theoretical physicist, whose contributions in areas as diverse as neutron stars, ultracold atomic gases, low-temperature and condensed matter physics have set standards for the fields. Applying concepts across disciplines he has achieved penetrating physical insights. His theories of neutron stars are classic: he co-developed the first consistent descriptions of dense matter from low densities to the liquid interior in neutron stars and in stellar collapse; proposed that compact X-ray sources are accreting neutron stars, and has driven our understanding of neutron star cooling. In condensed matter physics, he provided the basis of understanding of liquid helium-3 at nonzero temperature, and showed how related ideas could be applied to the transport properties of heavy-fermion compounds, and in a very different context, quark matter at high densities. Pioneered applying condensed matter concepts to ultracold atomic gases, successfully bridging the gap between atomic and condensed-matter physics. Awarded the Onsager Prize and the Bethe Prize of the American Physical Society.
PRACE grant to the NBIA
The EU Partnership for Advanced Computing in Europe (PRACE) provides access to world-class resources by allocating computing time at the five largest computers in Europe to research and industry. NBIA researchers Jacob Trier Frederiksen, Colin McNally, Gareth Murphy and Martin Pessah, as part of an international team led by NBI’s Troels Haugbølle, have been awarded 75 million CPU hours. It is the second largest EU computing grant given to any European research group, and represents 27% of all EU computing time at the largest super-computer in Europe.
If a corresponding amount of computing power would be acquired by buying computers or computing time at commercial data centers it would cost more than 3.5 million Dkr. The grant will allow the NBIA team and their collaborators at the Natural History Museum and the Niels Bohr Institute to make groundbreaking models of how stars are formed from dense molecular gas, and better understand how accretion discs made of gas and dust, that eventually become planets, evolve around newborn stars

Martin Pessah receives ERC Starting Grant
The European Research Council has awarded Martin Pessah a prestigious Starting Grant for 13.3 million Kroner to investigate fundamental problems related to the formation, evolution, and observational properties of planets, stars, and black holes.
"Understanding how celestial bodies gain mass during their lives by means of a rotating, gaseous disk surrounding them has been an outstanding problem in astrophysics for well over four decades. The goal of this project is to build upon state-of-the-art numerical codes and theoretical models in order to investigate how the small-scale physical processes determine the global, observable disk properties. Because of the fundamental role that accretion disks play in many environments, this research program will have profound implications across many branches of astrophysics. The combination of local expertise at the NBI, including the Computational Astrophysics Group, the Center for Star and Planet Formation, and the Dark Cosmology Centre, offer an unparalleled multidisciplinary environment to carry out my research program.", says Martin Pessah.
Martin Pessah received his first degree in Astronomy at the University of La Plata, Argentina. He obtained his PhD in Theoretical Astrophysics in 2007 at the University of Arizona. He was later a member of the prestigious Institute for Advanced Study at Princeton. In 2010, he became an Assistant Professor at the NBIA, with the goal of building a Theoretical Astrophysics group.

Christina Thoene publishes paper in Nature
In what is probably NBIA's first science paper in the prestigeous journal 'Nature', frequent NBIA visiting scientist Christina Thoene is first author on a paper that describes an unusual stellar death on Christmas Day 2010. A gamma-ray burst was observed by the Swift satellite on that day, and the subsequent evolution of thie star that caused this burst was monitored. Such gamma-ray bursts are the most powerful explosions in the universe. They result from a stellar explosion where a portion of the stellar material collapses into a black hole, while the remainder is shot out into the universe. In the process, the dying star rotates very quickly and a disc of incidental material forms around the newly formed black hole. The gamma-ray outburst typically lasts only a few minutes. The gamma-ray burst that was observed on the 25th of December 2010 lasted more than half an hour. This is longer than most gamma-ray bursts previously observed and at the same time it behaved very strangely. What Christina Thoene had found was nothing less than an entirely new kind of stellar death. This became obvious in the following days, when the object was followed closely. The tell-tale signs of this new kind of stellar death is the subesequent thermal -- blackbody -- radiation. Perhaps the reason why it has not been observed for other stars earlier may be the necessity of the star to be so close that the faint thermal radiation can be detected.
Emil Bjerrum-Bohr is elected member of Young Academy at Royal Academy of Sciences and Letters
NBIA scientist Emil Bjerrum-Bohr becomes member of the prestigious Young Academy at the Royal Academy of Sciences and Letters.

The purpose of the the Young Academy is to strengthen basic research and cross-disciplinarian exchange, to build bridges between sciences and society and to give some of Denmark's brightest young researchers a voice in the public debate.
Gordon Baym shares 2011 Eugene Feenburg Memorial Medal
Former NBIA Board member and Adjunct Professor at the Niels Bohr Institute Gordon Baym will share the 2011 Eugene Feenburg Memorial Medal with Leonid Keldysh. Baym was cited "for the self-consistent conserving approach to many-body perturbation theory that provided a solid platform for perturbative expansions, and for his novel applications of quantum many-body methods to nuclear physics, astrophysics, highly condensed matter, and atomic physics." He will receive the award at a special ceremony during the 16th Recent Progress in Many-Body Physics international conference in Bariloche, Argentina in late November.
NBIA post-doc Andres Reynoso receives an honorable mention as part of the J.J Giambiagi 2011 Award

NBIA scientist Emil Bjerrum-Bohr receives prestigious Junior Group Leader grant from the Lundbeck Foundation
Emil Bjerrum-Bohr has been awarded 10 million kroner by the Lundbeck Foundation to establish his own research group at the NBIA and the Discovery Center.
The Lundbeck Foundation’s award of 10 million kroner will be given over a period of 5 years, and it will be possible to create three new postdoc positions and one PhD position. This grant from the Lundbeck Foundation will allow him to establish and lead his own research group, the Amplitude Computation Group (CAMP), at the NBIA and the Discovery Center.
“My project is pioneering work with the goal of creating stronger connections between experimental and theoretical physics. With large experimental facilities like the LHC-accelerator at CERN, we are entering a new era of research, where particle physics must be understood on far smaller distances and at higher energy densities. The aim of the project is to find new methods for making accurate predictions of which particles will be formed in proton collisions at CERN. In particle physics these predictions are called scattering amplitudes. However, these new methods may also lead to an entirely new understanding of physics. That’s where it gets really exciting!”, explains Emil Bjerrum-Bohr.
Emil Bjerrum-Bohr received his PhD from the Niels Bohr Institute in 2004. He has had a successful international scientific career first in Great Britain and later in the U.S. at the Institute for Advanced Studies in Princeton. In 2009 he returned to Denmark to assume a newly established research position as Knud Højgaard Assistant Professor in particle physics at the NBIA.

NBIA Board member Herbert Spohn receives the Dannie Heinemann Prize
New member of the NBIA Board, Professor Herbert Spohn of the Technical University of Munich receives the 2011 Dannie Heinemann Prize for Mathematical Physics. Herbert Spohn receives the prize “For his seminal contributions to nonequilibrium statistical mechanics as exemplified by his exact solutions of growth models and stationary states of open systems. Combining mathematical rigor with physical insight his work elucidates the transition from microscopic to macroscopic behavior.”.
The prestigious Heinemann Prize was established in 1959 by the Heineman Foundation for Research, Educational, Charitable, and Scientific Purposes, Inc., and is administered jointly by the American Physical Society and the American Institute of Physics.
Herbert Spohn received his undergraduate education in Physics at the Technical University of Stuttgart and his Ph.D. degree in 1975 from the Ludwig-Maximilians-Universitat at Munchen. He was postdoc at Yeshiva University and Rutgers University with Joel Lebowitz and at Princeton University with Elliott Lieb. In 1982 he joined as associate professor the group of Herbert Wagner at the LMU. Since 1998 he is full professor at Zentrum Mathematik and Physik Department of the Technical University at Munchen. He has been visiting member at the IHES, Paris, and at the Institute for Advanced Studies. Herbert Spohn is most widely known through his work on interacting stochastic particle systems, in particular driven lattice gases, and his study of universal probability distributions for growth processes as connected to line ensembles and random matrix theory. He strived for a deeper understanding of how macroscopic laws emerge from the underlying motion of atoms. Spohn was awarded with the Max Planck Research Award, jointly with Lebowitz. He chaired the International Association of Mathematical Physics. He joined the NBIA Board in June 2010.
Chris Pethick receives the Hans A. Bethe Prize
The Executive Board of the American Physical Society has announced that the Hans A. Bethe Prize will be awarded to Chris Pethick “For fundamental contributions to the understanding of nuclear matter at very high densities, the structure of neutron stars, their cooling, and the related neutrino processes and astrophysical phenomena.”
The Hans A. Bethe Prize was established to recognize outstanding work in theory, experiment or observation in the areas of astrophysics, nuclear physics, nuclear astrophysics, or closely related fields. The Bethe Prize will be presented at the APS April 2011 meeting, at a special Ceremonial session.
Chris Pethick has had an essentially lifelong interest in neutron stars. A famous paper from 1970 that he wrote together with Gordon Baym and Hans Bethe resulted from a chance encounter at Nordita when they were all three in Copenhagen for longer-term visits. This was at a time when astrophysicists needed for the first time to understand in detail matter at nuclear densities. Their work formed the basis for much subsequent work and continues to be cited today. Later Chris in collaboration with others developed equations of state for matter in collapsing stars. He has also made fundamental contributions to the understanding of neutrino processes in dense matter and the cooling of neutron stars. He continues to play a very active role in the field, as is illustrated by a paper on neutron star structure that will appear in Physical Review Letters in October.
