Overactivated transport in the localized phase of the superconductor-insulator transition
V. Humbert, M. Ortũno, A. M. Somoza +3
Beyond a critical disorder, two-dimensional (2D) superconductors become insulating. In this Superconductor-Insulator Transition (SIT), the nature of the insulator is still controve…
Unbinding transition in semi-infinite two-dimensional localized systems
A. M. Somoza, P. Le Doussal, M. Ortuno
We consider a two-dimensional strongly localized system defined in a half-space and whose transfer integral in the edge can be different than in the bulk. We predict an unbinding t…
Phase diagram of weak-magnetic-field quantum Hall transition quantified from classical percolation
M. Ortuño, A. M. Somoza, V. V. Mkhitaryan +1
We consider magnetotransport in high-mobility 2D electron gas in a non-quantizing magnetic field. We employ a weakly chiral network model to test numerically the prediction of the…
Nonlinear conductivity of two-dimensional Coulomb glasses
M. Caravaca, A. M. Somoza, M. Ortuño
We have studied the nonlinear conductivity of two-dimensional Coulomb glasses. We have used a Monte Carlo algorithm to simulate the dynamic of the system under an applied electric…
Conductance fluctuations in the localized regime
A. M. Somoza, J. Prior, M. Ortuno
We have studied numerically the fluctuations of the conductance, , in two-dimensional, three-dimensional and four-dimensional disordered non-interacting systems. We have checked…
