This dissertation explores various generalizations of global symmetries and ’t Hooft anomalies. Chapter two is based on work with Po-Shen Hsin and Nathan Seiberg [1]. It is dedicated to the study of one-form global symmetries in three and four dimensions. We investigate their physical implications, classify their ’t Hooft anomalies and analyze...

### FPO - Ho Tat Lam - "On Symmetries, Anomalies and Their Generalizations"

### FPO - Sarah Marie Bruno - "Focal Plane Development for Observations of the Cosmic Microwave Background with the Simons Observatory"

A promising avenue for studying the origin and evolution of the universe is to measure the Cosmic Microwave Background (CMB), the thermal radiation remaining from the Big Bang after billions of years of expansion. Today, this remnant takes the form of an extraordinarily uniform thermal blackbody of ~2.7 K in temperature.

### FPO - Fedor Popov - "New Developments in Vector, Matrix and Tensor Quantum Field Theories"

### FPO - Javier Roulet - "The Binary Black Holes of LIGO and Virgo"

Over the last six years, the LIGO and Virgo gravitational wave detectors have revolutionized gravitational wave astronomy by discovering the first compact binary mergers. There is much to learn about how these systems form in nature, and these discoveries have allowed to start characterizing the astrophysical population of binary black holes....

### FPO - Elmer Guardado-Sanchez - "Exploring many-body quantum dynamics with Rydberg-dressed fermions and tilted Hubbard systems"

Ultracold atomic gases in optical lattices are an ideal platform for studying quantum many-body physics. The long timescales and isolated nature of these systems makes them particularly suited for exploring the dynamics of nearly closed quantum systems and their relaxation towards thermal equilibrium.

### FPO - Ziming Ji - "Non-Archimedean and Non-local Physics”

Physics defined on real manifolds and equipped with locality has achieved many successes theoretically as well as in describing our universe. Nevertheless, from a mathematical point of view, it is not as privileged. This thesis explores the possibility of non-Archimedean and non-local physics by studying a range of discrete and continuous...

### Summer Research Talk Series for Undergraduates

The EDI committee for undergraduate recruitment is starting up our summer research talk series aimed at undergraduates. The goal of this series is to have graduate students and post-docs give accessible talks about their research and how they got involved in their particular field.

### Special Condensed Matter Seminar - Yichen Huang, MIT, "Entanglement dynamics from random product states at long times"

We study the entanglement dynamics of quantum many-body systems at long times.

### FPO - Benjamin Weiner - "The Physics of Spatial Differentiation in Living Systems"

Living systems exhibit spatial differentiation at every scale, from the functional compartments within cells to the biogeography of multi-species communities.

### EDI initiative "All Hands" meeting

All working groups will present ~5-10 minutes of updates on their ongoing projects. We're looking forward to seeing you all then!

(Zoom link will be sent via departmental email and the EDI Slack channel.)

### Condensed Matter Zoom Seminar | Srinivas Raghu, Stanford | "Lattice constructions of a web of dualities in 3 spacetime dimensions"

Duality transformations have played a major role in our modern understanding of quantum phenomena. In 3 spacetime dimensions, familiar examples of duality transformations include 1) Goldstone modes of the XY model being dual to a photon, and 2) dualities involving statistical transmutation. It has become clear recently that both of these...

### Reunion event - Blasts from the Past: PU Physics Highlights 2016-2021

Abstract:

### FPO - Average Phan - "Swarm Intelligence in Natural and Synthetic Lives"

Real world phenomenon are inherently nonlinear and complex in a way that usually cannot be understood from first principle. Yet intelligence behaviors appear in biological systems, which are shaped by billions years of evolution, to solve natural challenges.

### Condensed Matter Zoom Seminar | Andrea Young, UCSB | "Orbital magnetism in graphene heterostructures"

I will describe experiments probing magnetic states based on the spontaneous alignment of electron orbitals.
