Abstract: I shall describe the recent theoretical advances in the description of turbulence in different media.

An important point is how different the meaning of renormalization in turbulence is from what we used to know in the field theory.

For...

Abstract: Based on https://arxiv.org/abs/2408.11139(Link is external) (Link opens in new window) . In pure Einstein gravity, the amplitude for an arbitrary number of positive helicity gravitons to scatter is zero at tree-level. If a single negative...

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...
