The sound of quintessence: analogue Kiselev acoustic black holes
Luis C. N. Santos, H. S. Vieira, Franciele M. da Silva +1
In this work, we demonstrate that the geometry of a spherically symmetric black hole surrounded by a Kiselev anisotropic fluid can be effectively mimicked by an experimental setup…
Quasibound states of massive charged scalars around dilaton black holes in dimensions: Exact frequencies
H. S. Vieira
In this work, we investigate massive charged scalar perturbations in the background of three-dimensional dilaton black holes with a cosmological constant. We demonstrate that the w…
Vortices without inflow: bound spectra in horizonless rotational analogs
H. S. Vieira, Kyriakos Destounis
Analog gravity experiments are making remarkable strides in unveiling both the classical and quantum nature of black holes. By harnessing diverse states of matter, contemporary tab…
Perturbing the vortex: quasinormal and quasibound spectra of rotating acoustic geometries
H. S. Vieira, Kyriakos Destounis, Kostas D. Kokkotas
Strong-field gravity simulators are laboratory experiments that can investigate a wide range of both classical and quantum phenomena occurring in nature. In this work, we introduce…
