Title: Foundation Models for Science: What happens if we train large (language) models on scientific data? - Shirley Ho
Mon, Sep 25, 2023, 4:30 pm5:30 pm

Abstract: In recent years, the fields of natural language processing and computer vision have been revolutionized by the success of large models pretrained with task-agnostic objectives on massive, diverse datasets. This has, in part, been driven by the use of self-supervised pretraining methods which allow models to utilize far more training…

Special Seminar:Josephson junction arrays as a platform for topological phases of matter|Omri Lesser (Weizmann Inst)|May 4 @3:30pm Joseph Henry Rm
Thu, May 4, 2023, 3:30 pm5:00 pm

The search for low-dimensional topological superconductivity is fueled by the promise of new and exotic physics, such as chiral superconductivity and non-Abelian anyons. However, the need to break time-reversal symmetry, usually by applying a relatively large external magnetic field, has hindered the realization of these novel phases of matter…

Condensed Matter:Instanton Density Operator in Lattice QCD from Higher Category Theory | Jingyuan Chen ,Tsinghua University (Beijing)|A06 5/1 @2PM
Mon, May 1, 2023, 2:30 pm3:30 pm

A long standing problem in lattice QCD is to construct an explicit instanton density operator on the lattice. We introduce such a construction, after suitably refining the lattice Yang-Mills action, so that it captures the continuum Yang-Mills theory better than the traditional lattice Yang-Mills action does. This refinement needed follows…

Special Seminar: (Machine) Learning of Dark Matter| Lina Necib (MIT)|Joseph Henry Rm @3PM
Fri, Apr 21, 2023, 3:00 pm4:30 pm

In this talk, I present different machine learning and data driven techniques that produce measurements of stellar kinematics around the Milky Way, and relate them to our understanding of Dark Matter. More specifically, I will discuss a data driven technique applied to Gaia DR3 combined with Apogee data to produce the circular velocity…

Special Seminar - From Quantum Circuits to Gravity inside the Black Hole - Ying Zhao, UCSB
Thu, Mar 2, 2023, 4:00 pm5:00 pm

Abstract:  Black holes have not just become laboratories for astronomers, but also present some of the deepest unsolved problems in theoretical physics. During the past decade scientists learned that concepts from quantum information play a key role in understanding fundamental problems in gravity. In this talk I will explain some recent…

Special Seminar - Towards a physics of learning and decision-making - Gautam Reddy - Harvard University
Wed, Feb 22, 2023, 2:00 pm3:00 pm

Abstract: Living systems sense their physical environment and process this information to interact back with the environment. This continual loop that iterates between sensing, computation and action drives the emergence of complex behaviors. Physics plays a key role in this sensorimotor loop by imposing constraints on all of its basic elements…

Special Seminar: "Designing quantum matter in two dimensions"
Wed, Jan 4, 2023, 11:00 am12:00 pm

Experimental condensed matter research is undergoing a revolution. Before, the need for 3D crystalline samples with a given structure and doping set stringent requirements for realization of the desired properties. Now, it is possible to create tunable 2D samples in the lab, overcoming the previous limitations and speeding up the research. Here…

Special Seminar: "Hofstadter states and re-entrant charge order in a semiconductor moiré lattice"
Tue, Jan 3, 2023, 11:00 am12:00 pm

Abstract: In this talk, I will present local electronic compressibility measurements on a twisted transition metal dichalcogenide heterobilayer, which reveal a rich phase diagram of Hofstadter states and novel electron crystalline orders. We show that this reflects the coexistence of both flat and dispersive moiré bands whose…

Special Seminar, Dicke Candidate Shengkai Li, Georgia Institute of Technology, "Field-mediated Interaction in Active Matter" December 3, 2021, Jadwin 481
Fri, Dec 3, 2021, 10:00 am10:00 am

Like most physical systems, in active matter, the characteristics of interaction play an important role. For example, the extent of attraction can switch a collective of particles from a homogeneous mixture to phase-separated clusters. Further, particle concavity in shape-changing active systems can change…
