The black hole information paradox has been an important problem in quantum gravity. In the study of evaporating black hole, it has been proposed that the holographic map between the semi-classical effective description in bulk and the fundamental description in boundary cannot be isometric. In this work, we would like to study the reflected entropy in an evaporating black hole model through...
The QCD phase diagram is essential for understanding strongly interacting matter under extreme conditions, with important implications for cosmology, neutron stars, and heavy-ion experiments. We present a novel holographic QCD model utilizing neural ordinary differential equations (ODEs) to map the QCD phase diagram under magnetic field $B$, baryon chemical potential $\mu_B$, and temperature...
In this talk I will give a new interpretation for the bulk extremal surface homologous to a boundary time-like interval, as the gravitational anomalous part of an entanglement entropy. This entanglement entropy is exactly the one associated to the space-like interval that shares the same causal development with the time-like one.
This talk will report an experimental simulation of bulk entanglement entropy (BEE) and boundary-boundary correlation function (BBCF) of scalar fields in two types of hyperbolic lattices, serving as the discretized regularizations of spatial geometries of pure AdS2+1 spacetime and AdS2+1 black hole, respectively. We experimentally confirm that BEE exhibits universal logarithmic scaling with...
