Circulation and operational sparsity of analogue Hawking radiation in rotating acoustic horizons
Fernando M. Belchior, Joao A. A. S. Reis, Edilberto O. Silva
Temporal sparsity compares the mean interval between emitted quanta with a characteristic single-quantum timescale. We study this operational quantity for the rotating draining-bat…
Thermodynamics and emergent thermomechanical response of a quantum ring with nonminimal spin--orbit coupling
João A. A. S. Reis, L. Lisboa-Santos, Edilberto O. Silva
We investigate the thermodynamic and emergent thermomechanical properties of fermions confined to a one-dimensional quantum ring with effective spin--orbit interactions induced by…

Edilberto O. Silva, João A. A. S. Reis, Faizuddin Ahmed
We construct a consistent anti-de Sitter completion of the static and spherically symmetric black-hole solution sourced by the Palatini-inspired nonlinear electrodynamics \(Y^n\) m…
Geometric Phases and Persistent Spin Currents from nonminimal couplings
Edilberto O. Silva, João A. A. S. Reis, L. Lisboa-Santos
We investigate a class of nonminimal derivative couplings between fermions and electromagnetic fields that generate Rashba-like spin--orbit interactions in one-dimensional quantum…
