Dyonic Kerr-Sen Black Hole's Resonant Scattering: Absorption and Superradiance

S. Katewongveerachart, D. Senjaya

We analytically investigate scalar superradiant scattering in the rotating dyonic Kerr-Sen black hole of Einstein-Maxwell-Dilaton-Axion theory. Starting from the separable Klein-Go…

The Spectroscopy of the 2+1 Dimensional Analog Black Hole in Photon-Fluid Model

David Senjaya, Supakchai Ponglertsakul

In this paper, we explore quasibound states (QBS), scalar cloud, Hawking radiation, superradiance, and greybody factor of relativistic massive phonon modes in a photon-fluid rotati…

Scalar Instabilities Inside The Extremal Dyonic Kerr-Sen Black Hole: Novel Exact Solutions and Chronology Protection Conjecture

David Senjaya, Teephatai Bunyaratavej, Piyabut Burikham

We investigate the stability of test scalar fields in the region inside the extremal Dyonic Kerr-Sen black hole (DKSBH) horizon, where closed timelike curves exist. We successfully…

The Spectroscopy of Kerr-Einstein-Maxwell-Dilaton-Axion: Exact Quasibound States, Scalar Cloud, Horizon's Boson Statistics and Superradiance

David Senjaya, Supakchai Ponglertsakul

In the present study, we investigate the quasibound states, scalar cloud and superradiance of relativistic scalar fields bound to a rotating black hole in Einstein-Maxwell-Dilaton-…

Revisiting Chronology Protection Conjecture in The Dyonic Kerr-Sen Black Hole Spacetime

Teephatai Bunyaratavej, Piyabut Burikham, David Senjaya

The Chronology Protection Conjecture (CPC) was first introduced by Hawking after his semi-classical investigation to the behaviour of a spacetime with closed timelike curves (CTCs)…

The extremal Reissner-Nordström black holes: an exact charged scalar quasiresonance

David Senjaya, Supakchai Ponglertsakul

In this letter, we present a novel exact scalar quasibound states solutions in the extremal Reissner-Norström black hole background. We start with the construction of the governing…
