Engineering Higgs dynamics by spectral singularities
H. P. Ojeda Collado, Nicolò Defenu, José Lorenzana
We generalize the dynamical phase diagram of a Bardeen-Cooper-Schrieffer condensate, considering attractive to repulsive, i.e., critical quenches (CQ) and a non-constant density of…
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…
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…
Impurities and electronic localization in graphene bilayers
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro
We analyze the electronic properties of bilayer graphene with Bernal stacking and a low concentration of adatoms. Assuming that the host bilayer lies on top of a substrate, we cons…
