Quasinormal modes of a quantum inspired black hole in four dimensions with cosmological constant
R. D. B. Fontana, Jeferson de Oliveira, B. Eslam Panah +1
We study the scalar and Dirac perturbations of quantum-corrected black holes with cosmological constant. Using two different methods (WKB and double-null characteristic integration…
Causal structure of black holes immersed in a Chaplygin-like dark fluid environment: Horizons and singularities
Rodrigo Dal Bosco Fontana, Jeferson de Oliveira
In the present work, we study the causal structure of spherically symmetric black holes immersed in a Chaplygin-like dark fluid, emphasizing the impact of the fluid parameters on c…
Gauge-covariant Raychaudhuri dynamics for spin-nondegenerate Lorentz-violating congruences
A. A. Araújo Filho, A. F. Santos, J. A. A. S. Reis +2
We investigate the Raychaudhuri dynamics of charged spin-nondegenerate Lorentz-violating particle congruences under minimal electromagnetic coupling. The coupling is introduced thr…
Thermoforesis from generalized Caldeira-Leggett models
Daniel Valente, Maurício Matos, Thiago Werlang
The standard Caldeira-Leggett model addresses the problem of Brownian motion in a thermal equilibrium environment. Here, we look for generalizations of the Caldeira-Leggett model t…
Dissipative adaptation in a driven spin-boson model within the path-integral formalism
Elisa Iahn Goettems, Ricardo J. S. Afonso, Diogo O. Soares-Pinto +1
We investigate the dissipative adaptation hypothesis in a quantum regime using a system-reservoir approach. This hypothesis proposes that self-organization arises from a system's a…
Tuning of exciton type by environmental screening
Igor L. C. Lima, M. V. Milošević, F. M. Peeters +1
We theoretically investigate the binding energy and electron-hole (e-h) overlap of excitonic states confined at the interface between two-dimensional materials with type-II band al…
