Title: Position-dependent mass scalar field theory, curved spacetime and asymptotic Weyl symmetry
Abstract:
We investigate a class of (1+1)-dimensional inhomogeneous—position-dependent mass—scalar field theories that can be classically converted to field theories on curved spacetime. This conversion enables us to quantize such inhomogeneous field theories by using the Hadamard method. Employing locally Hadamard states, we compute renormalized two-point functions and covariantly conserved energy-momentum tensors, uncovering interesting consequences: Unruh-like effect in bubble wall expansion at zero temperature. Furthermore, we uncover an approximate asymptotic Weyl symmetry, whose anomaly can be interpreted as arising from the boundary term under the variation. These results establish a coherent framework for quantizing and extracting meaningful physics from position-dependent mass field theories and their curved-spacetime counterparts.

Title: Towards Quantum Black Hole Microstates
Abstract:
I will review the recent surge of interest in finding quantum microstates of black holes, under the name of black hole cohomologies or fortuity. I will go over the progress in the 4d N=4 Super-Yang-Mills with gauge groups SU(2), SU(3) and SU(4), introduce related studies in other theories such as the ABJ(M) theory, and discuss possible applications of this subject. The talk will be based on works by myself as well as by many others.
