Princeton 2018: CMB-S4 Workshop

Thu, Sep 6, 2018, 8:00 am to Sat, Sep 8, 2018, 4:00 pm

Registration will be held in McDonnell Hall (A -Level)

FPO - David Zajac "Single Electron Spin Qubits In Silicon Quantum Dots"

FPO - Po-Shen Hsin - "Symmetries, Anomalies and Duality in Chern-Simons Matter Theories"

Wed, Aug 29, 2018, 2:00 pm

This thesis investigates the properties of quantum field theory with Chern-Simons interaction in three spacetime dimension. We focus on their symmetries and anomalies. We find many theories exhibit the phenomenon of duality - different field theories describe the same long-distance physics, and we will explore its consequence.

Atomic Physics Seminar | Luigi De Marco, U of Colorado | "Fermi Degenerate Polar Molecules: Controlling Chemistry with Quantum Statistics" | Jadwin 303

Mon, Aug 27, 2018, 1:00 pm

Ultracold polar molecules have long been heralded as ideal candidates for exploring a plethora of exotic phenomena in molecular and many-body physics. These include the study of chemistry in the quantum regime, the emulation of strongly-interacting spin models, the production of topological phases, and the exploration of fundamental symmetries...

FPO - Shai Chester - "Bootstrapping M-theory"

Mon, Aug 13, 2018, 2:00 pm

M-theory is a quantum theory of gravity in 11 dimensions that could possibly describe our world. Unfortunately, it is difficult to study and little is known about it beyond a few quantities that are protected by supersymmetry.

FPO - Zachary Sethna - “Probability, Entropy, and Adaptive Immune System Repertoires”

Mon, Aug 13, 2018, 10:00 am

The adaptive immune system, composed of white blood cells called lymphocytes (B and T cells) that circulate in the lymph and blood, is a precision tool that tags and removes foreign peptides. Such peptides, also called antigens or epitopes, are identified by a specific binding to elements of a library or repertoire of unique proteins called...

FPO - Siddharth Mishra Sharma - "Extragalactic Searches for Dark Matter Annihilation"

Fri, Aug 10, 2018, 11:00 am

We are at the dawn of a data-driven era in astrophysics and cosmology. A large number of ongoing and forthcoming experiments combined with an increasingly open approach to data availability offer great potential in unlocking some of the deepest mysteries of the Universe.

FPO - Daniel J. Strouse - "OPTIMIZATION OF MUTUAL INFORMATION IN LEARNING: EXPLORATIONS IN SCIENCE"

Thu, Aug 9, 2018, 2:00 pm

This thesis explores three applications of information theory in machine learning, all involving the optimization of information flow in some learning problem. In Chapter 2, we introduce a method for extracting the most informative bits that one signal contains about another.

FPO - Gustavo Turiaci - "Black Holes and Chaos"

Thu, Aug 2, 2018, 9:30 am

We study some aspects of quantum chaos and its relation to scattering near the black hole event horizon, in the context of gauge/gravity dualities. Chaos is an important ingredient related to the onset of thermalization. A signal of chaos is given by the behavior of out-of-time-ordered correlators (OTOC) and exponential growth of commutators....

FPO - Yuntao Bai - "Positive Geometry of the S-Matrix"

Wed, Aug 1, 2018, 2:00 pm

The search for a theory of the S-Matrix has revealed unprecedented structures underlying amplitudes. In this text, we present a new framework for understanding a class of amplitudes that includes Yang-Mills, Non-linear Sigma Model, the bi-adjoint cubic scalar, planar N=4 super Yang-Mills, and more.

FPO - Xin Xiang "Cherenkov Related Backgrounds in DarkSide-50 Experiment"

Tue, Jul 31, 2018, 11:00 am

Weakly Interacting Massive Particles (WIMPs) remain the most popular dark matter candidate as of 2018. DarkSide-50 is a dark matter direct detection experiment at Gran Sasso National Laboratory in Italy. The primary mission of DarkSide-50 is to detect the nuclear recoil signals created by WIMPs scattering off Argon nuclei in a background-free...

FPO - Kevin T. Crowley - "In Search of Inflation: Tools for Cosmic Microwave Background Polarimetry"

Fri, Jul 27, 2018, 10:00 am

The pursuit of knowledge of the early universe via the properties of the cosmic mi­crowave background ( CMB) is now being guided by the need to perform measure­ments of large-scale polarization patterns at a part in 100 million.

FPO - William Coulton - “Cosmology from the bispectrum”

Fri, Jul 6, 2018, 2:00 pm

With a suite of current and up-coming experiments set to provide us the with exquisite measurements of the sky in a wide range of frequencies, we are posed with the problem of how to maximally utilize these data sets. Historically two-point function measurements have been the tool of choice, and they have been highly effective.

FPO - Chengliang Zhu - “Study of Argon Electroluminescence Light Yield using Data from DarkSide-50”

Thu, Jul 5, 2018, 2:00 pm

Abstract

Since the secondary scintillation signals of dual phase Time Projection Chamber (TPC) detectors are produced through noble gas electroluminescence, a comprehensive understanding of electroluminescence is essential for the design and simulation of a future detector.
