Events Archive

Many innate behaviors are the result of multiple sensorimotor programs that are dynamically coordinated to produce higher-order behaviors such as courtship or architecture. Extended phenotypes such as architecture are especially useful for ethological study because the structure itself is a physical record of behavioral intent.

One might expect high-temperature transport to be incoherent and diffusive. However, many experimentally relevant one-dimensional systems, such as the Heisenberg and Hubbard models, feature long-lived quasiparticles that give rise to anomalous transport.

 I will show that every three-dimensional N=4 superconformal field theory on the squashed sphere contains a set of protected operators whose correlation functions are governed by a one-dimensional theory.

Noble Liquid Time Projection Chambers are ubiquitously used in the field of rare events searches such neutrinoless double beta decay or dark matter. A detailed understanding of light and charge transport in liquid xenon or liquid argon is of the utmost importance when modeling the performance of these experiments.

To date, LHC searches have provided no definitive evidence for physics beyond the Standard Model (BSM). What if we’re looking in the wrong place? Long-lived particles (LLPs) arise from a variety of well-motivated BSM theories.

Connecting theoretical models for exotic quantum states to real materials is a key goal in quantum materials synthesis.  Two-dimensional model systems have been proposed to host a wide variety of exotic phases- historically a number of techniques have been used to realize these including thin film growth and mechanical exfoliation.  We describe...

Abstract:

Guided by the principles of effective field theory, I will discuss three consecutive avenues to constrain physics beyond General Relativity with black-hole observations.
