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 …

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 …

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

A Josephson radiation threshold detector (JRTD) that is based on the threshold behaviour of
a current bias Josephson junction (CBJJ) is designed and fabricated for infrared radiation …

The Josephson junction, as a threshold detector, is studied in the presence of noise and a
weak external signal in the framework of the pendulum model. A range of parameters …

The direct effect of an axion field on Josephson junctions is analyzed through the
consequences on the effective potential barrier that prevents the junction from switching …

In the realm of physics, a pivotal moment occurred six decades ago when Brian Josephson
made a groundbreaking prediction, setting in motion a series of events that would eventually …

A bstract This study investigated the hybridization between an axion and plasmon polariton,
attributed to the coupling achieved by combining modified electrodynamics and …

We propose a new experimental technique to generate and detect axions in the lab with a
good experimental sensitivity over a broad axion mass range. The scheme relies on using …

We numerically investigate the behavior of a Josephson traveling wave parametric amplifier
assuming a current-phase relation with a second--harmonic contribution. We find that …
