Superconductor-insulator transition in Josephson junction chains by quantum Monte-Carlo
D. M. Basko, F. Pfeiffer, P. Adamus +2
We study the zero-temperature phase diagram of a dissipationless and disorder-free Josephson junction chain. Namely, we determine the critical Josephson energy below which the chai…
Critical properties of loop percolation models with optimization constraints
Frank O. Pfeiffer, Heiko Rieger
We study loop percolation models in two and in three space dimensions, in which configurations of occupied bonds are forced to form closed loop. We show that the uncorrelated occup…
Superconductor-to-Normal Phase Transition in a Vortex Glass Model: Numerical Evidence for a New Percolation Universality Class
Frank O. Pfeiffer, Heiko Rieger
The three-dimensional strongly screened vortex-glass model is studied numerically using methods from combinatorial optimization. We focus on the effect of disorder strength on the…
Dislocations in the ground state of the solid-on-solid model on a disordered substrate
Frank O. Pfeiffer, Heiko Rieger
We investigate the effects of topological defects (dislocations) to the ground state of the solid-on-solid (SOS) model on a simple cubic disordered substrate utilizing the min-cost…
Numerical study of the strongly screened vortex glass model in an external field
F. Pfeiffer, H. Rieger
The vortex glass model for a disordered high-T_c superconductor in an external magnetic field is studied in the strong screening limit. With exact ground state (i.e. T=0) calculati…
