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,…
Relativistic Superfluids in Curved Spacetime
Kristian Hauser A. Villegas
Superfluids under an intense gravitational field are typically found in compact stellar cores. Most treatments of these superfluids, however, are done using a flat spacetime backgr…
Lattice gauge theory and gluon color-confinement in curved spacetime
Kristian Hauser Villegas, Jose Perico Esguerra
The lattice gauge theory for curved spacetime is formulated. A discretized action is derived for both gluon and quark fields which reduces to the generally covariant form in the co…
Entanglement spectrum and number fluctuations in the spin-partitioned BCS ground state
Xavier M. Puspus, Kristian Hauser Villegas, Francis N. C. Paraan
We study entanglement between the spin components of the Bardeen-Cooper-Schrieffer (BCS) ground state by calculating the full entanglement spectrum and the corresponding von Neuman…
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…
