Dynamical phases transitions in periodically driven Bardeen-Cooper-Schrieffer systems
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro +2
We present a systematic study of the dynamical phase diagram of a periodically driven BCS system as a function of drive strength and frequency. Three different driving mechanism ar…
Bridge in micron-sized Bi2Sr2CaCu2O8+y sample act as converging lens for vortices
Joaquín Puig, Néstor René Cejas Bolecek, Jazmín Aragón Sánchez +3
We report on direct imaging of vortex matter nucleated in micron-sized Bi2Sr2CaCu2O8+y superconducting samples that incidentally present a bridge structure. We find that when nucle…
Emergent parametric resonances and time-crystal phases in driven BCS systems
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro +2
We study the out-of-equilibrium dynamics of a Bardeen-Cooper-Schrieffer condensate subject to a periodic drive. We demonstrate that the combined effect of drive and interactions re…
2D superconductidy driven by interfacial electron-phonon coupling at the BaPbO/BaBiO bilayer
S. Di Napoli, C. Helman, A. M. Llois +1
The recent discovery of 2D superconductivity at the interface of BaPbO (BPO) and BaBiO (BBO) has motivated us to study in depth the electronic and structural properties and…
Josephson coupling in high-T superconducting junctions using ultra-thin BaTiO barriers
H. Navarro, M. Sirena, Jeehoon Kim +1
We study the electrical transport of vertically-stacked Josephson tunnel junctions using GdBaCuO electrodes and a BaTiO barrier with thicknesses between 1 nm an…
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…
