Abstract: Can we regularize chiral global symmetries and their anomalies on a lattice with a finite dimensional Hilbert space? We discuss how the vector and axial U(1) symmetries of a massless Dirac fermion in 1+1d are realized in the conventional...

Abstract: On-shell methods have found a new application to local observables such as asymptotic radiation fields and gravitational waveforms. While these observables are invariant under small gauge transformations, they are known to depend on a...

Abstract: Energy and information are deeply connected in quantum field theory and quantum gravity. I will describe an explicit protocol for an observer outside a black hole to send in quantum information at zero energy cost. This clarifies what sort...

Abstract: On general grounds one expects that global symmetries are absent in quantum gravity. We discuss some aspects of this issue, focusing on the recently proposed Swampland Cobordism Conjecture, and related conjectures connected with...

Abstract: There is a surprising parallel between infinite temperature DSSYK and large N QCD which I will explain. The parallel may have much to tell us about the conjectured duality between DSSYK and JT de Sitter space. 

Abstract: I will describe the relationship between the Schur indices of 4d N=2 SQFTs of class S and the quantization of Chern-Simons theory with complex gauge group.

This will be a relaxed, informal gathering with only 2–3 talks each day, allowing ample time for in-depth discussions and collaborative exploration.

With recent developments in the field, we hope this meeting will serve as a valuable opportunity to...
