Abstract: We have performed extensive transport experiments on a 4-nm-thick aluminum (Al) superconducting film grown on a GaAs substrate by molecular beam epitaxy (MBE). Non-linear current-voltage (I-V) measurements on such a MBE-grown superconducting nanofilm show thatV~I3,… read more here.

DOI: 10.1103/physrevlett.127.156801
Abstract: The Berezinskii-Kosterlitz-Thouless (BKT) transition is the paradigmatic example of a topological phase transition without symmetry breaking, where a quasiordered phase, characterized by a power-law scaling of the correlation functions at low temperature, is disrupted by… read more here.

DOI: 10.1103/physrevlett.128.250402
Abstract: We probe local phase fluctuations of trapped two-dimensional Bose gases using matter-wave interferometry. This enables us to measure the phase correlation function, which changes from an algebraic to an exponential decay when the system crosses… read more here.

DOI: 10.1103/physrevlett.130.086704
Abstract: We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk material [Cu(pz)_{2}(2-HOpy)_{2}](PF_{6})_{2}. At zero field, a transition to long-range order occurs at 1.38 K, caused by… read more here.

DOI: 10.3390/ma14216294
Abstract: In this study, we measure the in-plane transport properties of high-quality Ba(Fe0.914Co0.086)2As2 single crystals. Signatures of vortex unbinding Berezinskii–Kosterlitz–Thouless (BKT) transition are shown from both the conventional approach and the Fisher–Fisher–Huse dynamic scaling analysis, in… read more here.
