The major task of detecting axions or axion-like particles has two challenges. On the one
hand, the ultimate sensitivity is required, down to the energy of a single microwave photon of …

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

An aluminium Josephson junction (JJ), with a critical current suppressed by a factor of three
compared with the maximal value calculated from the gap, is experimentally investigated for …

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 …

We discuss fluctuations near the second-order phase transition where the free energy has
an additional non-Hermitian term. The spectrum of the fluctuations changes when the odd …

The increased capabilities of coupling more and more materials through functional
interfaces are paving the way to a series of exciting experiments and extremely advanced …

Here, we experimentally test the applicability of an aluminium Josephson junction of a few
micrometers size as a single photon counter in the microwave frequency range. We have …

In superconductor-topological insulator-superconductor hybrid junctions, the barrier edge
states are expected to be protected against backscattering, to generate unconventional …

We have used Bi 2 Se 3 nanoribbons, grown by catalyst-free physical vapor deposition to
fabricate high quality Josephson junctions with Al superconducting electrodes. In our …

The interfacial coupling of two materials with different ordered phases, such as a
superconductor (S) and a ferromagnet (F), is driving new fundamental physics and …
