Proper-Time Approach in Asymptotic Safety via Black Hole Quasinormal Modes and Grey-body Factors
Bekir Can Lütfüoğlu, Erdinç Ulaş Saka, Abubakir Shermatov +3
We study the quasinormal mode spectrum and grey-body factors of black holes in an effectively quantum-corrected spacetime, focusing on the influence of near-horizon modifications o…
Gravitational quasinormal modes of Dymnikova black holes
Bekir Can Lütfüoğlu, Erdinç Ulaş Saka, Abubakir Shermatov +3
We investigate gravitational quasinormal modes of the Dymnikova black hole, a regular spacetime in which the central singularity is replaced by a de Sitter core. This geometry, ori…
Causal Viscous Fluids and Non-Singular Cosmological Bounces
L. Yildiz, D. Kayki, E. Gudekli
We investigate the realization of non-singular bouncing cosmologies driven by causal bulk-viscous fluids within General Relativity, gravity, and Loop Quantum Cosmology. Buil…
Non-Hermitian Gravitational Wave Scattering
Burak Pekduran, Mustafa Sarısaman, Ekrem Aydıner
In this study, the non-Hermitian scattering of gravitational waves is examined, and their behavior at spectral singularities is discussed. We investigate the non-Hermitian properti…
Gravitational waves in massive Horndeski theory with a potential
Hatice Özer, Özgür Delice
We investigate gravitational waves with an arbitrary potential within the framework of linearized Horndeski theory. We show that the minimum of the potential can play the role of a…
Displacement Memory Effect from Supersymmetry
Erdal Catak, Mahmut Elbistan, Mustafa Mullahasanoglu
We explain the recent results on the displacement memory effect (DME) of plane gravitational waves using supersymmetric quantum mechanics. This novel approach stems from that both…
