Theory of coherent quantum phase-slips in Josephson junction chains with periodic spatial modulations
Aleksandr E. Svetogorov, Masahiko Taguchi, Yasuhiro Tokura +2
We study coherent quantum phase-slips which lift the ground state degeneracy in a Josephson junction ring, pierced by a magnetic flux of the magnitude equal to half of a flux quant…

Resonant persistent currents for ultracold bosons on a lattice ring
Geva Arwas, Doron Cohen, Frank Hekking +1
We consider a one-dimensional bosonic gas on a ring lattice, in the presence of a localized barrier, and under the effect of an artificial gauge field. By means of exact diagonaliz…
