Time Like Geodesics of Regular Black Holes with Scalar Hair
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We investigate timelike geodesics in asymptotically flat regular black holes supported by a phantom scalar field characterized by a scalar charge . This parameter removes the ce…
Anomalous Decay Rate and Greybody Factors for Regular Black Holes with Scalar Hair
Ramón Bécar, P. A. González, Eleftherios Papantonopoulos +1
We study the propagation of massive scalar fields in the background of asymptotically flat regular black holes supported by a phantom scalar field with a scalar charge . This pa…
Lyapunov Exponents and Phase Transitions in Four-Dimensional AdS Black Holes with a Nonlinear Electrodynamics Source
Ramón Bécar, P. A. González, Felipe Moncada +1
We investigate the relationship between dynamical instability and thermodynamic phase transitions in four-dimensional Anti--de Sitter black holes in Einstein gravity coupled to a n…
Efficient Experimental Qudit State Estimation via Point Tomography
D. MartÃnez, L. Pereira, K. Sawada +7
Point tomography is a new approach to the problem of state estimation, which is arguably the most efficient and simple method for modern high-precision quantum information experime…
