The Josephson effect [1] represents perhaps the prototype of
macroscopic phase coherence and is at the basis of the most
widespread interferometer, i.e., the superconducting quantum
interference device (SQUID). Yet, in analogy to electric
interference, Maki and Griffin [2] predicted in 1965 that
thermal current flowing through a temperature-biased
Josephson tunnel junction is a...

Lee-Yang zeros are points in the complex plane of an
external field where the partition function vanishes and the
free energy diverges. In the thermodynamic limit, the
Lee-Yang zeros approach the real value of the field for
which a phase transition occurs. Lee-Yang zeros have been
investigated theoretically, but experimental observations of
Lee-Yang zeros remain scarce. Here, I describe...

Measurement of work done on a driven open quantum system
remains a major challenge in quantum thermodynamics. A
calorimetric detection method has been proposed by J. Pekola
and collaborators [1] as a feasible experimental scheme to
measure work and fluctuation relations in open quantum
systems. However, the detection requires a finite size for
the environment, which influences the system...
