    Physics Colloquium

    "Nature vs. Nurture in Complex (and Not-So-Complex) Systems"

    Presented by Daniel Stein, NYU

    3:30 pm, Large Seminar Room, Bldg. 510

    Tuesday, April 24, 2018, 3:30 pm

    Hosted by: Rob Pisarski

    Understanding the dynamical behavior of many-particle systems following a deep quench is a central issue in both statistical mechanics and complex systems theory. One of the basic questions centers on the issue of predictability: given a system with a random initial state evolving through a well-defined stochastic dynamics, how much of the information contained in the state at future times depends on the initial condition (``nature'') and how much on the dynamical realization (``nurture'')? We discuss this question and present both old and new results for both homogeneous and random systems in low and high dimension.

    Nuclear Theory/RIKEN Seminar

    "Exploring the QCD phase structure with functional methods"

    Presented by Bernd-Jochen Schaefer, University of Giessen

    2 pm, Building 510, CFNS Seminar Room 2-38

    Friday, April 27, 2018, 2:00 pm

    Hosted by: Chun Shen

    QCD at finite temperature and moderate densities predicts a phase transition from a chiral symmetry broken hadronic phase to a chirally restored deconfined quark-gluon plasma phase. In this talk I report on recent progress achieved basically with functional renormalization group (FRG) methods to reveal the QCD phase structure. Two and three quark flavor FRG investigations are confronted to results obtained with effective chiral low-energy models. The importance of quantum and thermal fluctuations is demonstrated and their consequences for the experimental signatures to detect possible critical endpoints in the phase diagram are discussed.

    Physics Colloquium

    "The Cosmic Microwave Background and How It Keeps on Revealing More about the Universe"

    Presented by Suzanne Staggs, Princeton

    3:30 pm, Large Seminar Room, Bldg. 510

    Tuesday, May 8, 2018, 3:30 pm

    Hosted by: Andrei Nomerotski

    In the 50+ years since its discovery, the cosmic microwave background (CMB) has yielded surprisingly detailed and precise information about the form, content and dynamics of the early universe. High angular resolution maps, and polarization data at all angular scales, are the focus of current and next-generation instruments. I will describe what we already know about the universe from the CMB, and lay the ground for future revelations from the CMB, with special emphasis on the Atacama Cosmology Telescope (ACT). ACT is a special-purpose 6m telescope situated at 17,000 ft in the dry Atacama Desert of northern Chile, at a latitude of 23 degrees South. ACT's millimeter-wave detectors measure both polarization and intensity at very fine angular scales (arcminutes). I will describe the ACT instrument and its data in the context of other ongoing and proposed CMB projects, their scientific impact, and the potential discovery space. I will include a brief description of the upcoming Simons Observatory.

    Nuclear Physics Seminar

    "TMD evolution as a double-scale evolution"

    Presented by Alexey Vladimirov, Universitat Regensburg

    11 am, Small Seminar Room, Bldg. 510

    Tuesday, May 15, 2018, 11:00 am

    Hosted by: Oleg Eyser

    Transverse momentum dependent (TMD) distributions depend on the pair of scaling parameters and their evolution is given by a pair of coupled equations. I present the analysis of the TMD evolution equations and their solution with the emphasis on their two-dimensional structure. It results in a new viewpoint on TMD evolution, both from the technical and interpretation sides. I formulate the non-perturbative definition of zeta-prescription and introduce the notion of optimal TMD distribution. I demonstrate that the updated form of TMD evolution produces lesser theoretical uncertainty and improves agreement with the data.
