|Raju Venugopalan Awarded Prestigious Humboldt Research Award|
Raju Venugopalan, an adjunct professor at Stony Brook University and a senior physicist at the U.S. Department of Energy’s Brookhaven National Laboratory, has been awarded a Humboldt Research Award for his remarkable achievements in theoretical nuclear physics. This prestigious international award — issued by the Alexander von Humboldt Foundation in Bonn, Germany — comes with a prize of €60,000 (nearly $70,000 U.S.) and the opportunity to collaborate with German researchers at Heidelberg University and elsewhere. Venugopalan joins 13 other Brookhaven National Laboratory physicists who have received this award since 1974.
“This is a great honor and I’m delighted to be in the company of other Humboldt winners over the past years,” Venugopalan said. “This award gives me a wonderful opportunity to build on and establish new collaborations with my colleagues in Germany, where I’ve been on sabbatical at the Institute for Theoretical Physics at Heidelberg University for the past year. I look forward to widening and deepening these connections.”
Venugopalan’s work is focused on developing theories to explain and predict the behavior of extreme forms of nuclear matter-including the several-trillion-degree soup of quarks and gluons, known as quark-gluon plasma (QGP), generated in energetic particle collisions at colliders like Brookhaven Lab’s Relativistic Heavy Ion Collider and Europe’s Large Hadron Collider He’s also explored the behavior of matter at the opposite temperature extreme, namely in ultra-cold atomic gases.

Chemistry and Physics Prof. Jin Wang and Physics Graduate Student Zhedong Zhang published "Origin of long-lived quantum coherence and excitation dynamics in pigment-protein complexes" in the Scientific Reports.
Nonequilibrium quantum statistical dynamics is of fundamental importance and critical for understanding of the energy and charge transports. The recent development of renewable energy demands the improvement of efficiency of energy and charge transports in materials. The widespread interests in exploring the quantum nature in solar cells and the antenna systems have been triggered by the experimental investigations of excitonic dynamics in a wide variety of systems, e.g., semiconductors, organic molecules, light harvesting complexes, natural and synthetic photosynthetic complexes. Even with the current knowledge of electronic structure in antenna and the advances in spectroscopy that uncovered the long-lived quantum coherence in fluctuating environment, the full understanding of the role of coherence and the mechanism of excitation energy transfer has still remained elusive.
In this study, a mechanism for a long standing issue of the origin of long-survived quantum coherence (e.g., light-harvesting complexes) for efficient energy transfer was uncovered in a general scenario. The bare electrons are surrounded by nuclear vibrational modes, which leads to the strong exciton-vibron coupling. The new composite called polaron gives rise to the screening and leads to much weaker interactions with the environments. The decoherence will then be significantly suppressed and the long-lived quantum coherence emerges. The nonequilibriumness from detailed balance breaking and coherence can funnel the downhill migration of excitons. The survival of quantum coherence is long enough to significantly improve the energy transfer efficiency under the breakdown of time-reversal symmetry. This result suggesting a mechanism of slowing down the dephasing is of importance for energy/charge transports and quantum information/computing.

|Researchers Receive INCITE Award to Study Stellar Explosions|
A project led by SBU Department of Physics and Astronomy professors Michael Zingale and Alan Calder has been awarded 45 million “processor hours” on the Titan Cray XK7, billed by host Oak Ridge National Laboratory as “the nation’s most powerful supercomputer for open science” (theoretical peak performance: 27,000 trillion calculations per second, or 27 petaflops).
Zingale and Calder – along with two SBU graduate students Donald Willcox and Maria Barrios as well as co-investigators from Oak Ridge, Lawrence Berkeley National Laboratory, the University of California, Los Alamo National Laboratory and the University of Tennessee – will spend their petaflops recreating complex astronomical events like X-ray bursts and white-dwarf explosions.
The idea is to gather clues needed to solve a host of astrophysics problems, with a particular focus on stellar explosions powered by fusion reactions.

|Sally Dawson received J.J. Sakurai Prize|
Brookhaven Lab particle physics theorist and Stony Brook University Adjunct Professor Sally Dawson has been named a recipient of the 2017 J.J. Sakurai Prize for Theoretical Particle Physics. Dawson and her co-recipients-Gordon L. Kane of the University of Michigan, Howard E. Haber of the University of California, Santa Cruz, and John F. Gunion of the University of California, Davis-are long-term and ongoing colleagues. They were cited for their "instrumental contributions to the theory of the properties, reactions, and signatures of the Higgs boson." They will receive the award, which consists of $10,000 to be shared and certificates citing their achievements, at a ceremony during an APS meeting themed "Quarks 2 Cosmos" on Sunday, January 29, 2017, in Washington, D.C.
Dawson is best known for developing mathematical models to explain and predict the processes by which Higgs particles are produced.
"You never would have found the Higgs if you didn't know what you were looking for," Dawson explained to further highlight the importance of the theory work. "The searches were based on years of calculations and the detectors were designed to find this thing based on that theoretical work, which is still ongoing," Dawson said. Today, Dawson and her colleagues are collaborating to more accurately predict the production and decay processes for Higgs particles at the LHC.

|2016 Nobel Prize in Physics|
The 2016 Nobel Prize in Physics "for theoretical discoveries of topological phase transitions and topological phases of matter" was awarded to David J. Thouless (University of Washington), F. Duncan M. Haldane (Princeton University), and J. Michael Kosterlitz (Brown University).
The use of topology in condensed matter physics goes back to studies of topological defects (vortices) in superfluid helium and solitons in polyacetylene in the seventies. The field boomed in the eighties after the discovery of Quantum Hall Effect by von Klitzing in 1980. By now the field of topological phases of matter is well established and is developing very quickly. This year's Nobel Prize recognizes major achievements and the importance of this field in modern physics.
Research on topological phases of matter is represented in the Department by Lukasz Fidkowski, Tzu-Chieh Wei and Alexander Abanov. One of the distinguishing features of studies in topological phases of matter is the constant collaboration of physicists representing very different disciplines such as condensed matter proper, nuclear theory, string theory, quantum information research, and mathematical physics. All these directions are well represented in the Department of Physics and Astronomy at Stony Brook University. The active research inspired by 2016 Nobel Prize winners at the Department is being done on geometry of Quantum Hall states, classification of topological phases of matter, transport in Weyl semimetals, entanglement and quantum computation, matrix product states, topological effects in QCD, and holographic approach to condensed matter physics as well as experimental studies of graphene and cold atoms.

|$10M Simons Collaboration on the Non-Perturbative Bootstrap|
Leonardo Rastelli of the YITP and the Department of Physics and Astronomy will lead a groundbreaking "Collaboration on the Non-Perturbative Bootstrap" as Director for a new grant that includes fourteen other principal investigators at institutions in the United States, Canada and Europe.
On August 25th, the Simons Foundation announced the establishment of the "Simons Collaboration on the Non-perturbative Bootstrap", with total funding of $10M over four years. Quantum Field Theory (QFT) is the language of modern theoretical physics. Quantum fields describe our knowledge of nature at the shortest distances, accessible by high energy accelerators, and also in phenomena like superconductivity, states of matter that can be created in the laboratory. A critical challenge for theoretical physics is to chart and understand the “space” of all possible QFTs, including strongly interacting models that are difficult to study by conventional methods. The Collaboration will bring to bear new theoretical tools, some developed here at the YITP, to address this question. The starting point is the astonishing discovery that the space of QFTs can be determined by using only general principles: symmetries and quantum mechanics. By analyzing the full implications of these general principles, one can make sharp predictions for physical observables without resorting to approximations. This strategy is called the bootstrap. New developments within the past few years suggest that the time is right for a concerted effort to open a new window on nature at its most fundamental. The Foundation considers the Collaboration as "the beginning of a much larger enterprise, crossing the traditional boundaries" in physics, mathematics and computer science.

|2016 Ettore Majorana Gold Medal for the Discovery of Supergravity|
Distinguished Professor Peter van Nieuwenhuizen of Stony Brook's C.N. Yang Institute for Theoretical Physics and the Department of Physics and Astronomy received the 2016 Ettore Majorana Gold Medal along with co-recipients Daniel Z. Freedman of Stanford and Sergio Ferrara of CERN for their role in the discovery of supergravity 40 years ago.
Supergravity is one of Stony Brook's greatest contributions to science. It generalized Einstein's theory of gravity by incorporating the then-novel idea of supersymmetry. The combination of these powerful ideas by Ferrara, Freedman and van Nieuwenhuizen showed that gravity may be unified with other forces in nature, and that in fact, this unification will predict as-yet unseen particles and forces between them.
