Magnetoelectric effect of a conducting sphere near a planar topological insulator
A. Martín-Ruiz, Omar Rodríguez-Tzompantzi, J. R. Maze +1
When time-reversal symmetry is broken on its surface, topological insulators exhibit a magnetoelectric response which is described by axion electrodynamics. A direct consequence of…
Quantum phase transition of two-level atoms interacting with a finite radiation field
L. F. Quezada, A. Martín-Ruiz, A. Frank
We introduce a group-theoretical extension of the Dicke model which describes an ensemble of two-level atoms interacting with a finite radiation field. The latter is described by a…
Gravitational Searches for Lorentz Violation with Ultracold Neutrons
C. A. Escobar, A. Martín-Ruiz
We investigate the consequences of Lorentz violation (as expressed within the gravity sector of the Standard-Model Extension) for gravitational quantum states of ultracold neutrons…
