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…
