The Kramers escape rate of phase transitions for the 6-dimensional Gauss-Bonnet AdS black hole with triple phases

open access: yesPhysics Letters B
In this study, we obtain specific picture of the phase transitions for the 6-dimensional Gauss-Bonnet Anti-de Sitter (AdS) black hole with triple phases, using the generalized free energy we constructed and Kramers escape rate in stochastic motion. There

Thermodynamics of a Non-Stationary Black Hole Based on Generalized Uncertainty Principle

open access: yesJournal of Physics: Theories and Applications, 2017
In the general theory of relativity (GTR), black holes are defined as objects with very strong gravitational fields even light can not escape. Therefore, according to GTR black hole can be viewed as a non-thermodynamic object.

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Entanglement Entropy in Black Hole microstates [PDF]

open access: yes, 2022
We review the thermodynamic behaviour and paradoxes arising from a classical description of Black Holes. Then we interpret them as solutions of Supergravity, seen as the low effective energy of Superstring Theory.

Bridging Scales: Modeling Suppressed Bondi Accretion on Black Holes and Its Impact on Galaxy Growth

open access: yesThe Astrophysical Journal
The accretion and feedback processes governing supermassive black hole (SMBH) growth span an enormous range of spatial scales, from the Event Horizon to the circumgalactic medium.

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

open access: yesAdvanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Black holes in the gravity/gauge theory correspondence [PDF]

open access: yes, 2002
The AdS/CFT correspondence provides a microscopic description of black hole thermodynamics. In this thesis, I study the relation between the classical physics of black holes and this microscopic description.

Coupling between black hole and cosmological solutions to Einstein’s equations [PDF]

open access: yes, 2023
openIn general relativity black holes are described as vacuum axisymmetric solutions to Einstein's equations. Since they are vacuum solutions, they tend to flat Minkowski spacetime at spatial infinity.

Photon Ring Astrometry. I. A Simple Spin Measurement Technique for High-resolution Images of M87*

open access: yesThe Astrophysical Journal
The supermassive black hole M87* is a target for future horizon-scale imaging that will resolve the first lensed ( n  = 1) subimage of the photon ring.

Supersymmetric black hole non-uniqueness in five dimensions

open access: yesJournal of High Energy Physics, 2019
We present a systematic study of the moduli space of asymptotically flat, supersymmetric and biaxisymmetric black hole solutions to five-dimensional minimal supergravity.
