The main aspects of the theory of phase transitions in two-dimensional degenerate systems
(Berezinskii–Kosterlitz–Thouless, or BKT, transitions) are reviewed in detail, including the …

What causes Cooper pairs to form in unconventional superconductors is often elusive
because experimental signatures that connect to a specific pairing mechanism are rare …

Two-dimensional superconductivity is primarily realized in atomically thin layers through
extreme exfoliation, epitaxial growth, or interfacial gating. Apart from their technical …

We developed novel techniques to fabricate atomically thin Bi 2.1 Sr 1.9 CaCu 2.0 O 8+ δ
van der Waals heterostructures down to two unit cells while maintaining a transition …

The Berezinskii-Kosterlitz-Thouless (BKT) transition is the paradigmatic example of a
topological phase transition without symmetry breaking, where a quasiordered phase …

Modern theories of melting of two-dimensional systems are discussed that are mainly based
on the concepts of the Berezinskii–Kosterlitz–Thouless (BKT) theory of phase transitions in …

In the past decades, considerable efforts have been made to understand the critical features
of both classical and quantum long-range (LR) interacting models. The case of the …

We report on the discovery and transport study of the superconducting ground state present
at the (111) LaAlO 3/SrTiO 3 (LAO/STO) interface. The superconducting transition is …

We investigate the effect of various fluctuation mechanisms on the DC resistance in
superconducting (SC) devices based on epitaxial titanium nitride (TiN) films. The samples …

The Berezinskii-Kosterlitz-Thouless (BKT) mechanism describes universal vortex unbinding
in many two-dimensional systems, including the paradigmatic XY model. However, most of …
