Abstract: In this talk, I will present recent developments in the study of Conformal Field Theories (CFTs) at finite temperature. The motivation for this work is different applications to holography, black holes in AdS as well as statistical physics...

Abstract: When electrons are forced to interact strongly with each other, some of the most exotic electronic phases and novel quasiparticles may emerge. A key approach to force electrons to strongly interact with one another is to confine them to...

Abstract: Non-invertible categorical symmetries have emerged as a powerful tool to uncover new beyond-Landau quantum phases and phase transitions. The general theory of such phases and transitions has been studied systematically primarily in (1+1)d...

Abstract: In the AdS/CFT correspondence, it is of great importance to understand the emergence of bulk geometry from quantum mechanical degrees of freedom on the boundary. Volumes of spatial subregions are key quantities characterizing the bulk...

Abstract: I will present a general Monte Carlo approach to the calculation of Feynman diagrams relevant to perturbative problems in collider physics, hot and dense QCD, non-relativistic many-body systems and classical physics.

Abstract: We consider quantum electrodynamics in 2+1 dimensions (QED3) with N matter fields and Chern-Simons level k. For small values of k and N, this theory describes various experimentally relevant systems in condensed matter, and is also...

Abstract: Astrophysical black holes are known to be rotating. Within classical General Relativity, the simplest spacetime solution (the Kerr solution) describing a rotating black hole reveals a traversable passage through an inner horizon – which in...

Abstract: Tensor network states are new kinds of variational wavefunctions that help us to understand quantum phases and phase transitions beyond Landau paradigm. In this talk, I will first review the major development of tensor network simulation...

Abstract: I will introduce a new 2d gravity/matrix integral duality. The bulk theory is a two-dimensional string theory defined by coupling two copies of Liouville CFT with central charges c = 13 ± is on the worldsheet. We call this string theory...
