Vavilov-Cherenkov radiation for parallel motion in three-dimensional topological insulators

O. J. Franca, Stefan Yoshi Buhmann

Our study delves into the modifications observed in Vavilov-Cherenkov radiation when its generating charged particle moves parallel to an interface formed by two generic magnetoele…

Modification of transition radiation by three-dimensional topological insulators

O. J. Franca, Stefan Yoshi Buhmann

We study how transition radiation is modified by the presence of a generic magnetoelectric medium with a special focus on topological insulators. To this end, we use the Green's fu…

Radiation from a dipole perpendicular to the interface between two planar semi-infinite magnetoelectric media

O. J. Franca, Luis F. Urrutia

We consider two semi-infinite magnetoelectric media with constant dielectric permittivity separated by a planar interface, whose electromagnetic response is described by non-dynami…

Lorentz violating scalar Casimir effect for a -dimensional sphere

A. Martín-Ruiz, C. A. Escobar, A. M. Escobar-Ruiz +1

We investigate the Casimir effect, due to the confinement of a scalar field in a -dimensional sphere, with Lorentz symmetry breaking. The Lorentz-violating part of the theory is…

A non-perturbative approach to the scalar Casimir effect with Lorentz symmetry violation

C. A. Escobar, A. Martín-Ruiz, O. J. Franca +1

We determine the effect of Lorentz invariance violation in the vacuum energy and stress between two parallel plates separated by a distance , in the presence of a massive real s…

Optical intersubband properties of a core-shell semiconductor-topological insulator quantum dot described by -Electrodynamics

Jorge David Castaño-Yepes, O. J. Franca, C. F. Ramirez-Gutierrez +1

The optical properties of a spherical topological insulator embedded concentrically in a single-electron system consisting of a core-shell GaAs quantum dot are analyzed, when the s…

Reversed electromagnetic Vavilov-Čerenkov radiation in naturally existing magnetoelectric media

O. J. Franca, L. F. Urrutia, Omar Rodríguez-Tzompantzi

We consider two semi-infinite magnetoelecteric media separated by a planar interface whose electromagnetic response is described by axion-electrodynamics. The time dependent Green'…

Explicit spacetime symmetry breaking in matter: the reversed Vavilov-Čerenkov radiation

O. J. Franca, L. F. Urrutia, Omar Rodríguez-Tzompantzi

We show that reversed Vavilov-Čerenkov radiation occurs simultaneously with the forward output in naturally existing materials when an electric charge moves with a constant velocit…

Emergent electrodynamics from the Nambu model for spontaneous Lorentz symmetry breaking

O. J. Franca, R. Montemayor, L. F. Urrutia

After imposing the Gauss law constraint as an initial condition upon the Hilbert space of the Nambu model, in all its generic realizations, we recover QED in the corresponding non-…
