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...
Abstract: The large-scale structure of our
Universe is well described by a model in which matter is
predominantly Cold Dark Matter (CDM). While CDM was initially
thought to have trouble reproducing the small scales of our
Universe (dwarf galaxies...
