Topological shadows and complexity of islands in multiboundary wormholes
Aranya Bhattacharya, Anindya Chanda, Sabyasachi Maulik +2
Recently, remarkable progress in recovering the Page curve of an evaporating black hole (BH) in Jackiw-Teitelboim gravity has been achieved through use of Quantum Extremal surfaces…
Temperature and Chemical Potential Dependence of the Parity Anomaly in Quantum Anomalous Hall Insulators
C. Tutschku, F. S. Nogueira, C. Northe +2
The low-energy physics of two-dimensional Quantum Anomalous Hall insulators like (Hg,Mn)Te quantum wells or magnetically doped (Bi,Sb)Te thin films can be effectively described by…
Holographic RG Flows for Kondo-like Impurities
Johanna Erdmenger, Charles Melby-Thompson, Christian Northe
Boundary, defect, and interface RG flows, as exemplified by the famous Kondo model, play a significant role in the theory of quantum fields. We study in detail the holographic dual…
Holographic Subregion Complexity from Kinematic Space
Raimond Abt, Johanna Erdmenger, Marius Gerbershagen +2
We consider the computation of volumes contained in a spatial slice of AdS in terms of observables in a dual CFT. Our main tool is kinematic space, defined either from the bulk…
