We study the metastability and decay of multiply charged superflow in a ring-shaped atomic
Bose-Einstein condensate. Supercurrent corresponding to a giant vortex with topological …

We experimentally investigate the stochastic phase dynamics of planar Josephson junctions
(JJs) and superconducting quantum interference devices (SQUIDs) defined in epitaxial …

Coherent passage of Cooper pairs in a Josephson junction (JJ) above the liquid nitrogen
temperature has been the first impressive revolutionary effect induced by high critical …

Superconducting nanocircuits, which are usually fabricated from superconductor films, are
the core of superconducting electronic devices. While emerging transition-metal …

Superconducting nanowire single-photon detectors (SNSPDs) are receiving the interest of
the scientific and industrial communities due to their unparallel high performances in the …

The investigation of the switching-current probability distribution of a Josephson junction is a
conventional tool to gain information on the dynamics of the phase slips as a function of the …

The importance of modulations is elevated to an unprecedented level, due to the delicate
conditions required to bring out exotic phenomena in quantum materials, such as …

Key questions for any superconductor include: what is its maximum dissipation‐free
electrical current (its 'critical current') and can this be used to extract fundamental …

We report on measurements of the switching current distributions on two-dimensional
superconducting NbTiN strips that are 5 nm thick and 80 nm wide. We observe that the width …

Superconducting circuits with nonlinear elements such as Josephson tunnel junctions or
kinetic inductance nanowires are the workhorse for microwave quantum and …
