In order to understand the emergence of superconductivity it is useful to study the reverse
process and identify the various pathways that lead to its destruction. One way is to increase …

Abstract Within the Bardeen–Cooper–Schrieffer (BCS) theory, superconductivity is entirely
governed by the pairing energy scale, which gives rise to the superconducting energy gap …

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

The magnetic-field-dependent critical current I c (B) of a Josephson junction is determined
by the screening currents in its electrodes. In macroscopic junctions, a local vector potential …

Superconductor-insulator transition (SIT) driven by disorder and transverse magnetic field
has been investigated in ultrathin MoN films by means of transport measurements and …

Recent experiments strongly indicate deep connections between transports of strange metal
and high T c superconductors. For instance, it is known that the dependence of the zero …

Continuous quantum phase transitions are widely assumed and frequently observed in
various systems of quantum particles or spins. Their characteristic trait is a second-order …

We image local superfluid density in single crystals of Pd-intercalated ErTe 3 below the
superconducting critical temperature T c, well below the onset temperature T CDW of …

We studied the role of reduced dimensionality and disorder in the superconducting
properties of wafer-scale aluminum (Al) nanofilms. This new generation of ultrathin films …

We find transport and spectroscopic signatures that are consistent with a magnetic field
induced transition from a vortex liquid to Bose metal in a two-dimensional amorphous …
