I will explain the relation between the Euclidean path integral over near-extremal black hole geometries and its dimensional reduction to 2D Jackiw-Teitelboim gravity. I will focus mostly on the case of 3D gravity and a particular application to pure 3D gravity.

In conformal field theory, in contrast to gapped theories, S-matrix is not well-defined. Similarly, various inclusive observables which make sense in a gapped theory, such as "energy squared" calorimeters, suffer from IR divergences in CFTs.

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

We propose a new test of strong-field general relativity (GR) based on the universal interferometric signature of the black hole photon ring. The photon ring is a narrow ring-shaped feature, predicted by GR but not yet observed, that appears on images of sources near a black hole.

A search is conducted for scalar top quarks decaying in the Full Run II dataset for the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) of 137.2\fbinv collected at a center of mass energy of √s = 14 TeV.

Abstract Quantum spin liquids(QSL) have fascinated physicists for nearly half a century since Anderson first introduced this concept with his resonating-valence-bond(RVB) idea in 1973. Although many progresses had been made, more challenges emerge from both theoretical and experimental perspectives.

This dissertation focuses on the generation of certain special disordered systems, as well as general tools that have been developed to characterize their microstructures. Particular attention is devoted to disordered hyperuniform systems, which are ex- otic amorphous states of matter that lie between crystals and liquids.
