Brookhaven Veterans Association
"Veterans Outreach Program"
11 am, Berkner Meeting Rooms C & D
Wednesday, October 2, 2013, 11:00 am
Hosted by: BERA Brookhaven Veterans Association
• If you have recently served in Iraq or Afghanistan, you may qualify for a service connected disability monthly cash payment if you experience Post Traumatic Stress Disorder. In the event that you do not at present suffer from PTSD, it may be a good idea to sign up for VA Healthcare should you start to experience any changes to your health status in the future. Veterans who served in other combat theatres who have PTSD but never signed up for VA benefits are eligible to do so. • If you take any medications on a regular basis, for any condition, you might have a zero copayment. This is also true for copayments for doctors' visits if you utilize the VA healthcare system. In no way would using the VA healthcare system for all or some conditions preclude your using your regular BNL health insurance. You are entitled to utilize the VA healthcare system as a result of your service to our country, and using it may qualify you for benefits that you do not have on your regular insurance plan. • Also, if you were exposed to Agent Orange during the Vietnam era and you have been diagnosed with diabetes or prostate cancer, you are eligible for a service connected disability in the form of a monthly cash payment. There are a number of other medical conditions for which you might also qualify for a service connected disability monthly cash payment. • The Veterans Administration ID card is considered an acceptable ID to prove you are a veteran for discounts at Home Depot, restaurants, and local merchants.

RIKEN/BNL Lunch Time Talk
"(Quasi) Nambu-Goldstone Fermion in QGP and Cold Atom System"
Presented by Daisuke Satow, RIKEN / BNL
12:30 pm, Physics, Building 510, Room 2-160
Thursday, October 3, 2013, 12:30 pm
Hosted by: Koji Kashiwa
It was suggested that supersymmetry (SUSY) is broken at finite temperature, and as a result, a Nambu-Goldstone fermion (goldstino) related to SUSY appears. Since dispersion relations of quarks and gluons are almost degenerate at extremely high temperature, quasi-zero energy quark excitation was suggested to exist though QCD does not have exact SUSY. As for the condensed matter system, a setup of cold atom system in which the Hamiltonian has SUSY was proposed, the goldstino was suggested to exist, and the dispersion relation of that mode at zero temperature was obtained recently.

Nuclear Physics & RIKEN Theory Seminar
"Resurgence theory, ghost instantons and analytical continuation of path integrals"
Presented by Gokce Basar, Stony Brook
2 pm, Small Seminar Room, Bldg. 510
Friday, October 4, 2013, 2:00 pm
Hosted by: Shu Lin
A general quantum mechanical or quantum field theoretical system in the path integral formulation has both real and complex saddles (instantons and ghost-instantons). Resurgent asymptotic analysis implies that both types of saddles contribute to physical observables, even if the complex saddles are not on the integration path i.e., the associated Stokes multipliers are zero. I show explicitly that instanton-anti-instanton and ghostâ€"anti-ghost saddles both affect the expansion around the perturbative vacuum via a self-dual model in which the analytic continuation of the partition function to negative values of coupling constant gives a pathological exponential growth, but a homotopically independent combination of integration cycles (Lefschetz thimbles) results in a sensible theory. These two choices of the integration cycles are tied with a quantum phase transition. The general set of ideas in this construction may provide new insights into non-perturbative QFT, string theory, quantum gravity, and the theory of quantum phase transitions.

C-AD Accelerator Physics Seminar
"Research on Alpha Emitters"
Presented by Dr. Ekaterina Dadachova, College of Medicine, Yeshiva University, NY
3:30 pm, Bldg 911B, Large Conf. Rm., Rm A202
Monday, October 7, 2013, 3:30 pm
"Alpha-emitters have been investigated for targeted therapy of cancer for several decades and some of the alpha-emitter based radiopharmaceuticals have been approved by FDA for clinical use or are in advanced stage clinical trials. In our laboratory we are investigating radioimmunotherapy of pancreatic cancer with 213Bismuth labeled antibodies to single stranded DNA. We have pioneered the use of alpha-emitters for radioimmunotherapy of infectious diseases including fungal, bacterial and viral (HIV) infections. Targeted alpha therapy is an effective and safe treatment modality for both cancer and infectious diseases."

"Application of the twist-3 framework to the high energy spin physics"
Presented by Shinsuke Yoshida, Nishina Center, RIKEN
12:30 pm, Physics, Building 510, Room 2-160
Thursday, October 17, 2013, 12:30 pm
Hosted by: Koji Kashiwa
: High energy hadron scattering is a powerful tool to investigate the internal structure of the hadrons. The perturbative QCD analysis have been successful in giving the quantitative description for many high energy processes and the knowledge of hadron structure based on the first principle. Recently some observables have shown the apparent disagreement with the conventional pQCD calculation. These novel observables have received much attention in recent decades and many theoretical works were proposed to solve the problems. In this talk, I introduce the twist-3 mechanism as the recent important progress of pQCD analysis. I especially discuss the application of the framework to the two unsolved problems, the single spin asymmetry and the proton spin problem.

Brookhaven Women In Science (BWIS) Event
"The truth and beauty in quasicrystals"
Presented by Marjorie Senechal, Smith College
4 pm, Berkner Hall Auditorium
Thursday, October 17, 2013, 4:00 pm
Hosted by: Vivian Stojanoff
The truth and beauty in quasicrystals Abstract: Like mosaics observed in our childhood kaleidoscope, quasicrystals show remarkable patterns that can not be repeated in a regular manner. Discovered in 1982 quasicrystals are very hard and break easily, like glass. Due to their unique properties they can be used to convert heat into electricity, in surface coatings for frying pans, or can be used in energy saving LED's. In this talk Senechal, Louise Wolf Kahn Professor Emerita in Mathematics and History of Science and Technology at Smith College, and Fellow of the American Mathematical Society, will discuss the beauty and applications of the patterns observed in artificial and natural quasicrystal structures.

Particle Physics Seminar
"Modeling Neutrino Quasielastic and Inelastic Scattering Using Electron Scattering Data"
Presented by Arie Bodek, University of Rochester
3 pm, Small Seminar Room, Bldg. 510
Thursday, October 24, 2013, 3:00 pm
Hosted by: David Jaffe
We show how electron scattering data from Jefferson Lab and SLAC is used to model Quasielastic and Inelastic neutrino charged current interactions on nuclear targets. The models which are currently implemented in the GENIE MC generator include: Bodek-Ritchie Fermi motion, Bodek-Yang modeling of inelastic neutrino interactions, and Bodek-Budd-Bradford-Avvakumov nucleon form factors. Most recently we have added the Bodek-Budd-Christy modeling of the transverse enhancement (Meson Exchange Currents) of quasielastic scattering on nuclear targets.

Physics Colloquium
"From unitary dynamics to statistical mechanics in isolated quantum systems"
Presented by Marcos Rigol, Pennsylvania State University
3:30 pm, Large Seminar Room, Bldg. 510
Tuesday, November 26, 2013, 3:30 pm
Hosted by: Rob Pisarski
Recently, experiments with ultracold gases have made it possible to study dynamics of (nearly) isolated many-body quantum systems. This has revived theoretical interest on this subject. In generic isolated systems, one expects nonequilibrium dynamics to result in thermalization: a relaxation to states where the values of macroscopic quantities are stationary, universal with respect to widely differing initial conditions, and predictable through the time-tested recipe of statistical mechanics. However, it is not obvious what feature of a many-body system makes quantum thermalization possible, in a sense analogous to that in which dynamical chaos makes classical thermalization possible. Underscoring that new rules could apply in the quantum case, experimental studies in one-dimensional systems have shown that statistical mechanics can provide wrong predictions for the outcomes of relaxation dynamics. Analyzing specific examples, we argue that generic isolated quantum systems do in fact relax to states where observables are well-described by statistical mechanical. Moreover, we show that time evolution itself plays a merely auxiliary role as thermalization happens at the level of individual eigenstates. We also discuss what happens at integrability points, where a different set of rules apply.
