We study the phase diagram of vortex matter in disordered type-II superconductors. We performed numerical simulations in the London Langevin approximation, using a new realistic representation of the disorder. At low magnetic fields we find a disenta

We study the physical properties of an $s$-wave--normal-metal--$d$-wave junction in terms of the Andreev bound-state solutions to the Bogoliubov--de Gennes equation in the normal-metal layer. The phase dependence of bound states with different orient

We present a microscopic study of the quantum fluctuations of the superconducting order parameter in thin homogeneous superconducting wires at all temperatures below T{sub c}. The rate of quantum phase-slip processes determines the resistance R(T) of

In a type II superconductor the gap variation in the core of a vortex line induces a local charge modulation. Accounting for metallic screening, we determine the line charge of individual vortices and calculate the electric field distribution in the

A superconductor connected to a normal metal by a tunnel junction induces a superconducting pair amplitude in the normal side. This proximity effect is profoundly modified by the Coulomb interaction: charging effects caused by the small capacitance o

We study numerically and experimentally the dynamics of driven vortex matter. Our London-Langevin simulations find that the critical current exhibits a peak both across the Bragg glass to vortex glass transition and across the melting line. The peak
We study the influence of a tunable dissipative environment on the dynamics of Josephson junction arrays near the superconductor-insulator transition. The experimental realization of the environment is a two dimensional electron gas coupled capacitiv

We study the response of two-dimensional Josephson-junction arrays and granular films of superconducting material near the superconductor-insulator transition. Close to the transition the system is described by a Ginzburg-Landau-Wilson free energy fu

We study dynamic properties of thin films near the superconductor - insulator transition. We formulate the problem in a phase representation. The key new feature of our model is the assumption of a {\it local} ohmic dissipative mechanism. Coarse grai

We present a microscopic derivation of the equation of motion for a vortex in a superconductor. A coherent view on vortex dynamics is obtained, in which {\it both} hydrodynamics {\it and} the vortex core contribute to the forces acting on a vortex. T
