Magnetic breakdown of cyclotron orbits in systems with Rashba and Dresselhaus spin-orbit coupling
A. A. Reynoso, Gonzalo Usaj, C. A. Balseiro
We study the effect of the interplay between the Rashba and the Dresselhaus spin-orbit couplings on the transverse electron focusing in two-dimensional electron gases. Depending on…
Anomalous Josephson Current in Junctions with Spin-Polarizing Quantum Point Contacts
A. A. Reynoso, Gonzalo Usaj, C. A. Balseiro +2
We consider a ballistic Josephson junction with a quantum point contact in a two-dimensional electron gas with Rashba spin-orbit coupling. The point contact acts as a spin filter w…
Casimir effect with dynamical matter on thin mirrors
C. D. Fosco, F. C. Lombardo, F. D. Mazzitelli
We calculate the Casimir energy for scalar and gauge fields in interaction with zero-width mirrors, including quantum effects due to the matter fields inside the mirrors. We consid…
Contact switching as a control strategy for epidemic outbreaks
Sebastian Risau-Gusman, Damian H. Zanette
We study the effects of switching social contacts as a strategy to control epidemic outbreaks. Connections between susceptible and infective individuals can be broken by either ind…
Variational approach to vortex penetration and vortex interaction
Alexander D. Hernández, Arturo López
A variational calculation for vortex penetration is presented. Variational trial functions for the Meissner state are combined with variational functions for a vortex near the surf…
Dimensional reduction as a method to obtain dual theories for massive spin two in arbitray dimensions
A. Khoudeir, R. Montemayor, Luis F. Urrutia
Using the parent Lagrangian method together with a dimensional reduction from to dimensions we construct dual theories for massive spin two fields in arbitrary dimensio…
