Suppression of non-equilibrium quasiparticle transport in flat band superconductors
Ville A. J. Pyykkönen, Sebastiano Peotta, Päivi Törmä
We study non-equilibrium transport through a superconducting flat-band lattice in a two-terminal setup with the Schwinger-Keldysh method. We find that quasiparticle transport is su…
Superconductivity, generalized random phase approximation and linear scaling methods
Sebastiano Peotta
The superfluid weight is an important observable of superconducting materials since it is related to the London penetration depth of the Meissner effect. It can be computed from th…
Universal suppression of superfluid weight by disorder independent of quantum geometry and band dispersion
Alexander Lau, Sebastiano Peotta, Dmitry I. Pikulin +2
Motivated by the experimental progress in controlling the properties of the energy bands in superconductors, significant theoretical efforts have been devoted to study the effect o…
Dynamical quantum phase transitions in strongly correlated two-dimensional spin lattices following a quench
Fredrik Brange, Sebastiano Peotta, Christian Flindt +1
Dynamical quantum phase transitions are at the forefront of current efforts to understand quantum matter out of equilibrium. Except for a few exactly solvable models, predictions o…
