Enhanced Correlations in Hawking Radiation from Near-Extremal Collapse
Suzanne Bintanja, Seolhwa Kim, Per Kraus
We consider the formation of a near-extremal Reissner-Nordstrom black hole by collapse, and show how to compute correlations in the outgoing Hawking radiation due to enhanced gravi…

Higher structure of non-invertible symmetries from Lagrangian descriptions
Seolhwa Kim, Orr Sela, Zhengdi Sun
The symmetry structure of a quantum field theory is determined not only by the topological defects that implement the symmetry and their fusion rules, but also by the topological n…

Codimension one defects in free scalar field theory
Seolhwa Kim, Per Kraus, Zhengdi Sun
We study various aspects of codimension one defects in free scalar field theory, with particular emphasis on line defects in two-dimensions. These defects are generically non-confo…
