We present a comprehensive investigation of the Berezinskii-Kosterlitz-Thouless transition
in ultrathin strongly disordered NbN films. Measurements of resistance, current-voltage …

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

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 …

The phase diagram of hole-doped high critical temperature superconductors as a function of
doping and temperature has been intensively studied with chemical variation of doping …

The nature of the superconducting transition in highly underdoped thick films of La 2− x Sr x
CuO 4 (x= 0.07 and 0.08) has been investigated using the in-plane transport measurements …

When materials' characteristic dimensions are reduced to the nanoscale regime, their
mechanical properties will vary significantly to that of their bulk counterparts. Recently low …

Occurrence of the Berezinskii-Kosterlitz-Thouless (BKT) transition is investigated by
superfluid density measurements for two-dimensional (2D) disordered NbN films with …

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

The Berezinskii-Kosterlitz-Thouless (BKT) transition in two-dimensional superconductors is
usually expected to be protected against disorder. However, its fingerprints in a real system …

Nonlinearity of IV characteristics below the transition temperature T c gets strongly affected
by the coupling channels between the superconducting planes in highly anisotropic …
