Metastability and Transient Effects in Vortex Matter Near a Decoupling Transition
C. J. Olson, C. Reichhardt, R. T. Scalettar +2
We examine metastable and transient effects both above and below the first-order decoupling line in a 3D simulation of magnetically interacting pancake vortices. We observe pronoun…
Effective temperature in driven vortex lattices with random pinning
Alejandro B. Kolton, Raphael Exartier, Leticia Cugliandolo +2
We study numerically correlation and response functions in non-equilibrium driven vortex lattices with random pinning. From a generalized fluctuation-dissipation relation we calcul…
Mode-locking in driven vortex lattices with transverse ac-drive and random pinning
Alejandro B. Kolton, Daniel Dominguez, Niels Gronbech-Jensen
We find mode-locking steps in simulated current-voltage characteristics of driven vortex lattices with {\it random} pinning when an applied ac-current is {\it perpendicular} to the…
Phase-locking of driven vortex lattices with transverse ac-force and periodic pinning
Charles Reichhardt, Alejandro B. Kolton, Daniel Dominguez +1
For a vortex lattice moving in a periodic array we show analytically and numerically that a new type of phase locking occurs in the presence of a longitudinal dc driving force and…
Complex Dynamical Flow Phases and Pinning in Superconductors with Rectangular Pinning Arrays
C. Reichhardt, G. T. Zimanyi, N. Gronbech-Jensen
We examine vortex pinning and dynamics in thin-film superconductors interacting with square and rectangular pinning arrays for varied vortex densities including densities significa…
Disordering Transitions in Vortex Matter: Peak Effect and Phase Diagram
C. J. Olson, C. Reichhardt, R. T. Scalettar +2
Using numerical simulations of magnetically interacting vortices in disordered layered superconductors we obtain the static vortex phase diagram as a function of magnetic field and…
Critical Currents and Vortex States at Fractional Matching Fields in Superconductors with Periodic Pinning
Charles Reichhardt, Niels Gronbech-Jensen
We study vortex states and dynamics in 2D superconductors with periodic pinning at fractional sub-matching fields using numerical simulations. For square pinning arrays we show tha…
Collective Multi-Vortex States in Periodic Arrays of Traps
Charles Reichhardt, Niels Gronbech-Jensen
We examine the vortex states in a 2D superconductor interacting with a square array of pinning sites. As a function of pinning size or strength we find a series of novel phases inc…
Driven vortices in 3D layered superconductors: Dynamical ordering along the c-axis
A. B. Kolton, D. Dominguez, C. J. Olson +1
We study a 3D model of driven vortices in weakly coupled layered superconductors with strong pinning. Above the critical force , we find a plastic flow regime in which pancake…
Static and dynamic coupling transitions of vortex lattices in disordered anisotropic superconductors
C. J. Olson, G. T. Zimanyi, A. B. Kolton +1
We use three-dimensional molecular dynamics simulations of magnetically interacting pancake vortices to study vortex matter in disordered, highly anisotropic materials such as BSCC…
Vortex Pinning and Dynamics in Layerd Superconductors with Periodic Pinning Arrays
Charles Reichhardt, Cynthia J. Olson, Niels Gronbech-Jensen
We examine vortex dynamics and pinning in layered superconductors using three-dimensional molecular dyanmics simulations of magnetically interacting pancake vortices. Our model tre…
Depinning and dynamic phases in driven three-dimensional vortex lattices in anisotropic superconductors
C. J. Olson, N. Gronbech-Jensen
We use three-dimensional molecular dynamics simulations of magnetically interacting pancake vortices to study the dynamic phases of vortex lattices in highly anisotropic materials…
Phase-Locking of Vortex Lattices Interacting with Periodic Pinning
Charles Reichhardt, Richard T. Scalettar, Gergely T. Zimanyi +1
We examine Shapiro steps for vortex lattices interacting with periodic pinning arrays driven by AC and DC currents. The vortex flow occurs by the motion of the interstitial vortice…
The Effect of Splayed Pins on Vortex Creep and Critical Currents
C. J. Olson, R. T. Scalettar, G. T. Zimanyi
We study the effects of splayed columnar pins on the vortex motion using realistic London Langevin simulations. At low currents vortex creep is strongly suppressed, whereas the cri…
