Weakly localised bosons
D. Das, S. Doniach
In this paper, we argue that, in 2-d, the weak localisation of bosons, which occurs on the insulating side of the superconductor-insulator transition, is characterised by $ρ\sim ln…

Dynamical Phase Transition in a Driven Disordered Vortex Lattice
Seungoh Ryu, M. Hellerqvist, S. Doniach +2
Using Langevin dynamics, we have investigated the dynamics of vortices in a disordered two dimensional superconductor subjected to a uniform driving current. The results provide di…

Field-driven topological glass transition in a model flux line lattice
Seungoh Ryu, A. Kapitulnik, S. Doniach
We show that the flux line lattice in a model layered HTSC becomes unstable above a critical magnetic field with respect to a plastic deformation via penetration of pairs of point-…
