Quasibound states of charged Dirac fields around Einstein-Euler-Heisenberg black holes
Nodirbek Anarboev, Javlonbek Khasanov, Javlon Rayimbaev +1
We study quasibound states of a massive charged Dirac field on the Einstein--Euler--Heisenberg (EEH) black hole, the extension of Reissner--Nordström (RN) by the leading weak-field…
Boundary-induced corrections to the response of an Unruh-DeWitt detector outside a compact star with Robin surface conditions
Nodirbek Anarboev, Javlonbek Khasanov, Javlon Rayimbaev +1
We formulate the finite-time response problem for a radially accelerated Unruh--DeWitt detector coupled to a real massless scalar field outside a static, spherically symmetric, hor…
Acceleration radiation, quasinormal modes and quasi-bound states in generic rotating regular black holes
Uktamjon Uktamov, Ali Övgün, Reggie C. Pantig +1
We study horizon-brightened acceleration radiation for a neutral scalar field in separable Kerr-like rotating metrics with nonlinear-electrodynamic mass profiles. The principal bra…
Regular black holes do not violate the first law of thermodynamics
Bobir Toshmatov, Bobomurat Ahmedov, Nozima Isamadinova +1
Regular black holes in general relativity coupled to nonlinear electrodynamics have been reported to exhibit an apparent mismatch in their thermodynamics: the temperature obtained…
Electromagnetic quasinormal modes of a Schwarzschild black hole in a superconducting plasma
Bobur Turimov, Akbar Davlataliev, Bobomurat Ahmedov +3
We formulate a generally covariant extension of London electrodynamics in four-dimensional curved spacetime and investigate the propagation of electromagnetic perturbations in a su…
Electrically charged regular black holes in higher dimensions: Maxwellian limit, branch point of the Lagrangian, and thermodynamics
Bobir Toshmatov, Bobomurat Ahmedov, Nozima Isamadinova +2
Electrically charged regular black holes in general relativity coupled to nonlinear electrodynamics are known to require a double-valued Lagrangian density , with a branch po…
Pulsar magnetospheres in dynamical Chern-Simons gravity: deathline conditions and polar-cap particle acceleration
Sherzod Sayfiyev, Bobomurat Ahmedov, Chengxun Yuan +3
The role of surface gravity in neutron stars (NSs) is considerable in the radiation mechanisms of the surrounding plasma magnetosphere near the star surface, as they are highly mag…
Perturbations and quasinormal modes of black holes in general relativity coupled to nonlinear electrodynamics
Uktamjon Uktamov, Bakhtiyor Narzilloev, Ibrar Hussain +2
We investigate the quasinormal spectra and time-domain evolution of scalar, electromagnetic, and gravitational perturbations of the Einstein-Bronnikov black hole in Einstein gravit…
Kerr-referenced analytical parametrization of rotating black holes in dynamical Chern-Simons gravity
Sardor Murodov, Bahodir Ahmedov, Bekzod Rahmatov +2
Rotating black holes in dynamical Chern-Simons gravity are known nonperturbatively mainly through numerical solutions, which limits their direct use in strong-field applications. W…
Weakly nonlinear strong-field signatures of spontaneously vectorized Einstein-vector-Gauss-Bonnet black holes near the Schwarzschild bifurcation
Sardor Murodov, Bekzod Rahmatov, Islom Egamberdiev +3
We study the static, spherically symmetric electric branch of spontaneously vectorized Einstein-vector-Gauss-Bonnet black holes close to its Schwarzschild bifurcation. A weakly non…
Massive neutral Dirac quasibound states in a Newman-Janis-generated rotating charged Kalb-Ramond black-hole geometry
Sardor Murodov, Olimjon Kholturayev, Bahodir Ahmedov +3
We study quasibound states of a massive neutral Dirac field in the Newman-Janis-generated rotating charged geometry used in Lorentz-violating Kalb-Ramond (KR) gravity. Rather than…
Probing Dark Matter and Phantom Field Effects on Neutrino Oscillations around Black Holes
Ikrom Ergashov, Bakhtiyor Narzilloev, Ibrar Hussain +1
This study investigates how dark matter in the background of the phantom field (DMPF) near a black hole influences neutrino flavor oscillations using a two-flavor model. It is foun…

We investigate horizon-brightened acceleration radiation (HBAR) and a strong-deflection expansion for the deflection angle of light rays scattered in the vicinity of a degenerate p…
