Thermodynamics, thermodynamic geometry, and the shadow of a Bardeen black hole surrounded by a Kiselev fluid: the role of regularity, asymptotics, and observational self-consistency

Hoang Van Quyet

We reconsider the Bardeen black hole surrounded by a Kiselev fluid, obtained by adding a Kiselev term to the Ayon-Beato-Garcia-Bardeen metric. Contrary to claims in the literature,…

Fold-Point Scaling and Phenomenological Cascade Closures in Regular Black Hole Spacetimes

Hoang Van Quyet

Semiclassical analyses of regular black holes suggest that inner-horizon instabilities can drive the trapped region to evaporate faster than the Hawking time and seed a transient a…

Synchrotron and Inverse-Compton Signatures of Black to White Hole Explosions: Weibel-Mediated External Shocks in the Interstellar Medium

Hoang Van Quyet

We study the non-thermal electromagnetic counterpart expected when the relativistic, near-isotropic ejecta of a black-to-white hole transition sweep up the interstellar medium (ISM…

Holographic Pressure and Extensivity of Rotating Black Holes at Finite Cutoff

Hoang Van Quyet

We investigate the quasi-local thermodynamics of rotating Kerr-AdS black holes enclosed by a finite timelike boundary (cavity). Extending recent work on static systems, we define t…

Critical Temperatures of Excited Holographic Superconductors in Born--Infeld Electrodynamics on a Reissner--Nordström--AdS Background

Hoang Van Quyet

We study the ground state (GS) and the two lowest excited states (ES1, ES2) of a probe holographic superconductor with Born-Infeld (BI) electrodynamics on a charged Reissner-Nordst…

Phase structure of a holographic topological superconductor beyond the probe limit

Hoang Van Quyet

We investigate tricritical phase transitions in a holographic model of topological superconductivity using Einstein-Maxwell gravity coupled with a charged scalar field in Anti-de S…
