Gauge-covariant Raychaudhuri dynamics for spin-nondegenerate Lorentz-violating congruences
A. A. Araújo Filho, A. F. Santos, J. A. A. S. Reis +2
The paper derives a gauge‑covariant form of the Raychaudhuri equation for charged particle congruences with Lorentz‑violating dispersion relations, showing how electromagnetic fiel…
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…
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…
Electromagnetic dynamics and geometric transport in spin-nondegenerate SME particles
A. A. Araújo Filho, A. F. Santos, J. A. A. S. Reis +2
We investigate the electromagnetic dynamics of spin-nondegenerate classical particle models arising from Lorentz-violating sectors of the Standard-Model Extension, focusing on the…
Fermions in -dimensions modified by nonminimal coupling and its applications to condensed matter physics
J. A. A. S. Reis, L. Lisboa-Santos, Fabiano M. Andrade +2
Fermions in two-dimensional space, commonly called -dimensional fermions, exhibit intriguing and distinctive characteristics that distinguish them from their higher-dimensio…
