Quantum phase transitions and vortex dynamics in superconducting networks

R Fazio, H Van Der Zant - Physics Reports, 2001 - Elsevier
Josephson-junction arrays are ideal model systems to study a variety of phenomena such as
phase transitions, frustration effects, vortex dynamics and chaos. In this review, we focus on …

Quantum phase transitions

S Sachdev - Physics world, 1999 - iopscience.iop.org
NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

Quantum phase transitions in two dimensions: Experiments in Josephson-junction arrays

HSJ van der Zant, WJ Elion, LJ Geerligs, JE Mooij - Physical Review B, 1996 - APS

Magnus force in superfluids and superconductors

EB Sonin - Physical Review B, 1997 - APS
The forces on the vortex, transverse to its velocity, are considered. In addition to the
superfluid Magnus force from the condensate (superfluid component), there are transverse …
