Negative Josephson coupling in the Kondo strong coupling limit
TLDR
In this article, it was shown that pair hopping through a Kondo singlet gives rise to a negative Josephson coupling, which supports the existence of staggered pair correlations in the strong coupling limit of a one dimensional Kondo lattice.Abstract:
We Show that pair hopping through a Kondo singlet give rise to a negative Josephson coupling. Thus, our calculation supports the existance of staggered pair correlations in the strong coupling limit of a one dimensional Kondo lattice.read more

TL;DR: In this paper, the work function of Ti3C2Tx can be increased by a UV-ozone treatment and decreased through a treatment with N2H4, which can be thus tuned in a range from 4.08 to 4.95 eV.
