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…
Jackiw-Teitelboim Gravity from the Karch-Randall Braneworld
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
In this letter, we show that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld. Notably the role of the dilaton in JT gravity is played by th…
Entanglement of Nambu Spinors and Bell Inequality Test Without Beam Splitters
Wei Luo, Hao Geng, D. Y. Xing +2
The identification of electronic entanglement in solids remains elusive so far, which is owed to the difficulty of implementing spinor-selective beam splitters with tunable polariz…
