CFT and Lattice Correlators Near an RG Domain Wall between Minimal Models
Cameron V. Cogburn, A. Liam Fitzpatrick, Hao Geng
Conformal interfaces separating two conformal field theories (CFTs) provide maps between different CFTs, and naturally exist in nature as domain walls between different phases. One…
Constraining braneworlds with entanglement entropy
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
We propose swampland criteria for braneworlds viewed as effective field theories of defects coupled to semiclassical gravity. We do this by exploiting their holographic interpretat…
Revisiting Recent Progress in the Karch-Randall Braneworld
Hao Geng
Motivated by the study of entanglement island in the Karch-Randall braneworld, it has been conjectured and proven in general that entanglement island is not consistent with long-ra…
BCFT in a Black Hole Background: An Analytical Holographic Model
Hao Geng, Lisa Randall, Erik Swanson
We study the entanglement phase structure of a holographic boundary conformal field theory (BCFT) in a two-dimensional black hole background. The bulk dual is the AdS black str…
Nonreciprocal Charge and Spin Transport Induced by Non-Hermitian Skin Effect in Mesoscopic Heterojunctions
H. Geng, J. Y. Wei, M. H. Zou +3
The pursuit of the non-Hermitian skin effect (NHSE) in various physical systems is of great research interest. Compared with recent progress in non-electronic systems, the implemen…
Aspects of AdS Quantum Gravity and the Karch-Randall Braneworld
Hao Geng
In this paper, we use the Karch-Randall braneworld to study theories of quantum gravity in two dimensional (nearly) anti-de Sitter space (AdS). We focus on effective gravitatio…
