Tp. Spiller et al., ON WEAK LINKS FED WITH IRREVERSIBLE CURRENTS, Nuovo cimento della Societa italiana di fisica. B, Relativity, classical and statistical physics, 110(2), 1995, pp. 125-131
We briefly discuss the usual time-reversible descriptions for displace
ment- and real-current-fed small-capacitance weak links. Many real lab
oratory current sources deliver charge in an intrinsically irreversibl
e fashion. We propose a phenomenological description of a weak link fe
d by such a source, and contrast its behaviour with the reversible pic
ture, using a simple example.
