Fragile-to-strong glass transition in two-dimensional vortex liquids
Ilaria Maccari, Lara Benfatto, Claudio Castellani +2
The fragile-to-strong glass transition is a fascinating phenomenon that still presents many theoretical and experimental challenges. A major one is how to tune the fragility of a g…
Transport signatures of fragile-glass dynamics in the melting of the two-dimensional vortex lattice
Ilaria Maccari, Bal K. Pokharel, Jasminka Terzic +8
In two-dimensional (2D) systems, the melting from a solid to an isotropic liquid can occur via an intermediate phase that retains orientational order. However, in 2D superconductin…
Uniformly frustrated XY model: strengthening of the vortex lattice by intrinsic disorder
Ilaria Maccari, Lara Benfatto, Claudio Castellani
In superconducting films, the role of intrinsic disorder is typically to compete with superconductivity by fragmenting the global phase coherence and lowering the superfluid densit…
Interplay of spin waves and vortices in the 2D XY model at small vortex-core energy
Ilaria Maccari, Nicolò Defenu, Lara Benfatto +2
The Berezinskii-Kosterlitz-Thouless (BKT) mechanism describes universal vortex unbinding in many two-dimensional systems, including the paradigmatic XY model. However, most of thes…
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…
