Biophysics Seminar speaker Vernita Gordon, UT Austin “Soft-matter mechanics in the initiation and robustness of bacterial biofilms.”

HET Seminar | Steve Gubser, Princeton University | "p-adic AdS/CFT"

Fri, Dec 2, 2016, 1:45 pm to 2:45 pm
I will give a first-principles introduction to p-adic numbers and p-adic AdS/CFT. p-adic numbers are an alternative to the real numbers, and they have a hierarchical structure which lends itself naturally to a holographic construction. The bulk dual to a p-adic boundary is the so-called Bruhat-Tits tree, an infinite regular graph.

Gravity Group Seminar, François Boulanger (Institut d'Astrophysique Spatiale, Orsay, France)

Fri, Dec 2, 2016, 12:00 pm to 1:30 pm

TITLE The interstellar B-fields crossing primordial CMB B-modes ABSTRACT Planck, as well as balloon and ground based experiments, have measured the polarization of the sky at sub-mm and mm wavelengths with unprecedented sensitivity. The data analysis involves research in cosmology and Galactic astrophysics, which might lead to a major discovery...

Hamilton Colloquium Series: Shivaji Sondhi, Princeton; "Statistical Mechanics, Localization and Periodically Driven Quantum Systems"

Thu, Dec 1, 2016, 4:00 pm to 5:00 pm

The statistical mechanics of equilibrium systems is characterized by two fundamental ideas: that closed systems approach a late time thermal state and that of phase structure wherein such late time states exhibit singular changes as various parameters characterizing the system are changed.

Physics Group Meeting | Greg Moore, Rutgers University | "Quantum Mechanics with Noncommutative Amplitudes"

Wed, Nov 30, 2016, 1:45 pm to 2:45 pm
I will fill in a few details concerning part three of my talk at Natifest.

Pheno & Vino Seminar, Francis-Yan Cyr-Racine, Harvard, "ETHOS - From dark particle physics to the matter distribution of the Universe and beyond"

Tue, Nov 29, 2016, 4:00 pm to 5:30 pm
The fundamental properties of dark matter can affect structure formation in our Universe in subtle ways. Unfortunately, many dark matter theories make similar predictions for how structure assembles on large and small scales, leading to a large degeneracy in model space.

HET Seminar | Igal Arav, Tel Aviv University | "Non-Relativistic Scale Anomalies and Geometry"

Tue, Nov 29, 2016, 1:30 pm to 2:30 pm
I will discuss the coupling of non-relativistic field theories to curved spacetime, and develop a framework for analyzing the possible structure of non-relativistic (Lifshitz) scale anomalies using a cohomological formulation of the Wess-Zumino consistency condition.

HET Seminar | Jaume Gomis, Perimeter Institute | “Correlation Functions in Superconformal Field Theories”

Mon, Nov 28, 2016, 2:30 pm to 3:30 pm
We discuss the exact determination of correlation functions of local operators in four-dimensional N=2 superconformal field theories.

Biophysics Seminar speaker Eric Siggia, Rockefeller U.

Mon, Nov 28, 2016, 12:00 pm to 1:00 pm
“Evolution as prediction: temperature compensated circadian clocks and how to change a fly into a mosquito".
Lunch @ 11:45, seminar 12-1:00.

HET Seminar | Bogdan Stoica, Brandeis University | "Tensor networks, p-adic fields, and algebraic curves: arithmetic and the AdS3/CFT2 correspondence"

Mon, Nov 21, 2016, 2:30 pm to 3:30 pm
One of the many remarkable properties of conformal field theory in two dimensions is its connection to algebraic geometry. Since every compact Riemann surface is a projective algebraic curve, many constructions of interest in physics (which a priori depend on the analytic structure of the spacetime) can be formulated in purely algebraic language.

Condensed Matter Seminar, Andrea Liu, U. Penn, "Jamming: A tale of two rigidities"

Mon, Nov 21, 2016, 1:15 pm to 2:15 pm
When we first learn the physics of solids, we are taught the theory of perfect crystals. Only later do we learn that in the real world, all solids are imperfect. The perfect crystal is invaluable because we can describe real solids by perturbing around this extreme limit by adding defects.

Biophysics Seminar speaker Ido Golding, Baylor College of Medicine "Deciphering the stochastic kinetics of gene regulation".

HET Seminar | Clay Cordova, Member, School of Natural Sciences, IAS | “Anomalies of 6d SCFTs”

Gravity Group Seminar, Stephan Schlamminger (NIST)

Fri, Nov 18, 2016, 12:00 pm to 1:30 pm

TITLE Measurements of the gravitational constant – why is a precise measurement so difficult? ABSTRACT In this presentation, I will summarize measurements of the Newtonian constant of gravitation, big G, that have been carried out in the last 30 years. I will describe key techniques that were used by researchers around the world to determine G...

Hamilton Colloquium Series: F. Duncan M. Haldane, Princeton; "Topological Quantum Matter"

Thu, Nov 17, 2016, 4:00 pm to 5:30 pm

The laws of quantum mechanics have been known for nearly a century, and have passed every test that has been made of them. But knowing them does not mean that we understand all that they permit.

Astroparticle Seminar: A.Chavarria-UChicago “A high-resolution CMOS imaging detector for the search of neutrinoless double beta decay in Se-82"

Wed, Nov 16, 2016, 2:00 pm to Wed, Nov 9, 2016, 3:00 pm
Abstract: The detection of neutrinoless double beta decay is the only known avenue to establish that neutrinos are Majorana fermions, as opposed to Dirac fermions.

Astroparticle Seminar: A.Chavarria-UChicago “A high-resolution CMOS imaging detector for the search of neutrinoless double beta decay in Se-82”

Math Physics Seminar, Vincent Vargas, ENS, "Ward and Belavin-Polyakov-Zamolodchikov (BPZ) identities for Liouville quantum field theory on the Riemann

Tue, Nov 15, 2016, 4:30 pm to 5:30 pm
The foundations of modern conformal field theory (CFT) were introduced in a 1984 seminal paper by Belavin, Polyakov and Zamolodchikov (BPZ). Though the CFT formalism is widespread in the physics literature, it remains a challenge for mathematicians to make sense out of it.

Pheno & Vino Seminar, David Pinner, Princeton University, "Unification and New Particles at the LHC"

Tue, Nov 15, 2016, 4:00 pm to 5:30 pm
Precision gauge coupling unification is one of the primary quantitative successes of low energy or split supersymmetry. Preserving this success puts severe restrictions on possible matter and gauge sectors that might appear at collider-accessible energies.

Senthil Todadri, Massachusetts Institute of Technology - "Symmetry Enriched Emergent U(1) Gauge Theories"

Mon, Nov 14, 2016, 2:30 pm to 4:00 pm
Phases of quantum many particle systems can have low energy effective field theoretic descriptions in terms of gauge theories in their deconfined phase.
