Spectral fingerprints of the non-linear dynamics of driven superconductors with dissipation
H. P. Ojeda Collado, Gonzalo Usaj, José Lorenzana +1
We study the out-of-equilibrium dynamics of a BCS superconductor in the presence of a periodic drive with a frequency larger than the equilibrium superconducting gap and an e…
Multi-orbital tight binding model for cavity-polariton lattices
Franco Mangussi, Marijana Milićević, Isabelle Sagnes +6
In this work we present a tight-binding model that allows to describe with a minimal amount of parameters the band structure of exciton-polariton lattices. This model based on …
Anomalous Goos-Hänchen shift in the Floquet scattering of Dirac fermions
A. Huamán, Gonzalo Usaj
We study the inelastic scattering of two-dimensional massless Dirac fermions by an inhomogeneous time-dependent driving field. As a physical realization we consider a monolayer gra…
Topological phase diagram of a three-terminal Josephson junction: From the conventional to the Majorana regime
Lucila Peralta Gavensky, Gonzalo Usaj, Carlos A. Balseiro
We study the evolution of averaged transconductances in three-terminal Josephson junctions when the superconducting leads are led throughout a topological phase transition from an…
Impurity states and Localization in Bilayer Graphene: the Low Impurity Concentration Regime
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro
We study the problem of non-magnetic impurities adsorbed on bilayer graphene in the diluted regime. We analyze the impurity spectral densities for various concentrations and gate f…
Fate of dynamical phases of a BCS superconductor beyond the dissipationless regimen
H. P. Ojeda Collado, Gonzalo Usaj, José Lorenzana +1
The BCS model of an isolated superconductor initially prepared in a nonequilibrium state, predicts the existence of interesting dynamical phenomena in the time-dependent order para…
