Large-c BCFT Entanglement Entropy with Deformed Boundaries from Emergent JT Gravity
Dominik Neuenfeld, Christopher Tellinger
We study the effect of boundary deformations on the von Neumann entropy of subregions in two-dimensional boundary conformal field theories (BCFTs) at zero and finite temperature. T…
The Flat-Space Limit of AdS Coupled to a Bath
Dominik Neuenfeld
We explain how to take a well-defined flat-space limit of brane models of AdS coupled to a non-gravitating bath. In the dual BCFT this amounts to a triple-scaling limit where both…
Real-Time Scattering in Ising Field Theory using Matrix Product States
Raghav G. Jha, Ashley Milsted, Dominik Neuenfeld +2
We study scattering in Ising Field Theory (IFT) using matrix product states and the time-dependent variational principle. IFT is a one-parameter family of strongly coupled non-inte…
Liouville gravity at the end of the world: Deformed defects in AdS/BCFT
Dominik Neuenfeld, Andrew Svesko, Watse Sybesma
We study shape deformations of two-dimensional end-of-the-world (ETW) branes, such as those in bottom-up models of two-dimensional holographic boundary conformal field theories (BC…
