We study the ground state and low energy excitations of vortices pinned to columnar defects in superconductors, taking into account the long–range interaction between the fluxons. We consider the “underfilled” situation in the Bose glass phase, where each flux line is attached to one of the defects, while some pins remain unoccupied. By exploiting an analogy with disordered semiconductors, we calculate the spatial configurations in the ground state, as well as the distribution of pinning…

Monte Carlo simulation of the crossover from Bose glass to Bragg glass phase in layered BSCCO with columnar defects
Monte Carlo simulations of layered BSCCO samples are used to investigate the behavior of vortex matter at low fields, particularly in connection with the possible occurrence of a Bragg glass (BrG)
Dynamic Approach to the Ground State of a Vortex System with Random Pinning
We study the ground state of a two-dimensional vortex system with random pinnings by cooling the vortex system to zero temperature. The peak of structure factor S(k) of vortices increases with vortex

Slow dynamics in glassy systems
Abstract We describe similarities in the features of various glassy systems where interactions and randomness compete. For example, Coulomb glasses have a gap in their single-particle density of
