Superconducting detectors have become an important tool in experimental astroparticle
physics, which seeks to provide a fundamental understanding of the Universe. In particular …

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 …

We review three different approaches to investigate the non-equilibrium stochastic dynamics
of a Josephson junction affected by Lévy-distributed current fluctuations. First, we study the …

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 the linear regime, thermoelectric effects between two conductors are possible only in the
presence of an explicit breaking of the electron-hole symmetry. We consider a tunnel …

The model of two coupled quantum pendula is studied and its suitability to describe
Josephson junctions interacting with axions is analysed. It is shown that some physical …

We propose a scheme for the detection of microwave-induced photons through a current-
biased Josephson junction, from the point of view of the statistical decision theory. Our …

We investigate an optimal scheme for the detection of single microwave photons by a
Josephson junction through the analysis of its switching times distribution. The proposed …

The recent developments in quantum technologies, as well as advanced detection
experiments, have raised the need to detect extremely weak signals in the microwave …

We propose to characterize Lévy-distributed stochastic fluctuations through the
measurement of the average voltage drop across a current-biased Josephson junction. We …
