Kane-Fisher weak link physics in the clean scratched-XY model
Gabriel Lemarié, Ilaria Maccari, Claudio Castellani
The nature of the superfluid-insulator transition in 1D has been much debated recently. In particular, to describe the strong disorder regime characterized by weak link proliferati…
Disordered XY model: effective medium theory and beyond
Ilaria Maccari, Lara Benfatto, Claudio Castellani
We study the effect of uncorrelated random disorder on the temperature dependence of the superfluid stiffness in the two-dimensional classical XY model. By means of a perturbative…
Melting of the vortex lattice through intermediate hexatic fluid in a-MoGe thin film
Indranil Roy, Surajit Dutta, Aditya N. Roy Choudhury +8
The hexatic fluid refers to a phase in between a solid and a liquid which has short range positional order but quasi-long range orientational order. In the celebrated theory of Ber…
BKT universality class in the presence of correlated disorder
Ilaria Maccari, Lara Benfatto, Claudio Castellani
The correct detection of the Berezinskii-Kosterlitz-Thouless (BKT) transition in quasi-two-dimensional superconductors still remains a controversial issue. Its main signatures, ind…
