Energy-momentum-squared gravity: charged quark star solutions with unified interacting matter
Ayan Banerjee, Bobur Turimov, Javlon Rayimbaev +3
We investigate the equilibrium structure of electrically charged quark stars within the framework of energy-momentum-squared gravity (EMSG), adopting a unified interacting quark-ma…
Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution
Bekir Can Lütfüoğlu, Mardon Abdullaev, Javlon Rayimbaev +2
We study axial gravitational perturbations of the neutral regular black hole generated by a non-local, T-duality-inspired zero-point length and the associated gravitational self-en…
Lorentz-Covariant Spectral Bounds from Thermal Quantum Field Theory
Alisher Sanetullaev, Sarbinaz Bazarbaeva, Marhabo Beymamatova +1
We derive rigorous Lorentz-covariant bounds on relaxation spectra directly from the analytic structure of retarded Green's functions in thermal quantum field theory, using only cau…
Lorentz-Covariant Spectral Bounds from Thermal Quantum Field Theory: Retarded Green's Functions, Kubo Relations, and Holographic Constraints
Alisher Sanetullaev, Sarbinaz Bazarbaeva, Marhabo Beymamatova +1
We extend the recently established framework of Lorentz-covariant relaxation bounds from linearized classical kinetic and rheological theories to the full quantum setting of therma…
Eikonal Ringing, Shadows, Lensing, Grey-Body Factors, and Binding Energy of Asymptotically Flat Regular Black Holes in Phantom Dirac-Born-Infeld Gravity
Mardon Abdullaev, Gumisbek Allambergenov, Diyorbek Rashidov +2
We develop a geodesic-optics description of eikonal quasinormal ringing, blackhole shadows, strong lensing, grey-body factors (GBFs), and the binding energy of massive particles fo…
Uniqueness for an inverse problem of determining order and temporal factor of the source for time-fractional evolution equations
Ravshan Ashurov, Masahiro Yamamoto
This paper addresses the inverse problem of simultaneously recovering the fractional order and the time-dependent source factor in the Cauchy problem…
