Quantum and higher curvature corrections to the anti-de Sitter black hole
Kristian Hauser A. Villegas, Reginald Christian Bernardo
Black holes exert quantum pressure coming from the nonlocal gravity correction. We investigate this nonlocal correction for black holes in anti-de Sitter (AdS) spacetime and its du…
Anomalous Higgs oscillations mediated by Berry curvature and quantum metric
Kristian Hauser A. Villegas, Bo Yang
Higgs spectroscopy, the study of Higgs bosons of a superconductor, is an emerging field in studying superconductivity. Here we show that the Berry curvature and the quantum metric…
Bose-Einstein condensate-mediated superconductivity in graphene
M. Sun, A. V. Parafilo, K. H. A. Villegas +2
We propose a mechanism for robust BCS-like superconductivity in graphene placed in the vicinity of a Bose-Einstein condensate. Electrons in the graphene interact with the excitatio…
Bogolon-mediated electron scattering in graphene in hybrid Bose-Fermi systems
Meng Sun, K. H. A. Villegas, V. M. Kovalev +1
We report on an unconventional mechanism of electron scattering in graphene in hybrid Bose- Fermi systems. We study energy-dependent electron relaxation time, accounting for the pr…
Blackhole evaporation model without information loss
Kristian Hauser A. Villegas
A simple model of a blackhole evaporation without information loss is given. In this model, the blackhole is \textit{not} in a specific mass eigenstate as it evaporates but rather,…
Non-stationary solutions driven by thermodynamic power in the white-noise Langevin model
Mikhail P. Solon, Kristian Hauser Villegas, J. P. Esguerra
The average thermodynamic power of a time-dependent external potential in the white-noise Langevin model is derived using a Green's function solution. The power appears as a drivin…
