Origin of the superconductor-insulator transition in disordered two-dimensional films
Alexander Weitzel, Lea Pfaffinger, Animesh Panda +8
Theory predicts the superconductor-to-insulator transition (SIT) to emerge from the competition between Anderson localization, which tends to localize single-particle wavefunctions…
Crossover and Critical Behavior in the Layered XY Model
Roman Kracht, Andrea Trombettoni, Ilaria Maccari +1
Motivated by the interplay between 2D and 3D scaling signatures observed in unconventional layered superconductors, we present a systematic Monte Carlo study of the three-dimension…
Tuning macroscopic phase frustration in multiorbital superconductors
Ilaria Maccari, Aline Ramires
Time-reversal symmetry-breaking (TRSB) superconductivity has been reported in a growing number of materials. In some cases, TRSB arises naturally from chiral superconductivity, but…
BKT phase transition in nanoporous films of superconducting NbN
A. Verma, R. Vedin, J. Jesudasan +3
We present a study of the Berezinskii-Kosterlitz-Thouless (BKT) transition in mildly disordered NbN nanoporous (NP) films. The measured superfluid stiffness, Js, is found to be muc…
