Current-driven vortex dynamics in untwinned YBa2Cu3O7 superconducting single crystals

Current-driven vortex dynamics of type-II superconductors in the weak-pinning limit is investigated by quantitatively studying the current-dependent vortex dissipation of an untwinned YBa2Cu3O7 single crystal. For applied current densities (J ) substantially larger than the critical current density (Jc), non-linear resistive peaks appear below the thermodynamic firstorder vortex-lattice melting...

Quantum Phase Transitions and Vortex Dynamics in Superconducting Networks

Josephson-junction arrays are ideal model systems to study a variety of phenomena such as phase transitions, frustration effects, vortex dynamics and chaos. In this review, we focus on the quantum dynamical properties of lowcapacitance Josephson-junction arrays. The two characteristic energy scales in these systems are the Josephson energy, associated with the tunneling of Cooper pairs between ...

Spin and vortex dynamics and electromagnetic propagation in the spontaneous vortex phase

We study the spin and vortex dynamics in the spontaneous vortex phase of magnetic superconductors. Equations of motion are derived which incorporate the coupling between the superconducting and magnetic components, as well as coupling between spin and vortex motion. We show that coupling between the spin and vortex degrees of freedom leads to new dynamical phenomena in the spontaneous vortex ph...
