We invite you to attend a talk presented by Dr. Hiba Assi, a candidate for a visiting physics professor position. Abstract: Deeper theoretical understanding of vortex matter in disordered type-II superconductors is crucial for material optimization for technological applications. We model magnetic flux lines in the London limit as interacting elastic lines subject to uncorrelated point defects or extended columnar disorder, and then simulate their dynamics utilizing a Langevin Molecular Dynamics algorithm. We disentangle the effects of the competing repulsive vortex-vortex interactions and pinning following magnetic field or temperature quenches. We discovered some universal features and others that depend on the type of disorder. *Research supported by the U.S. Department of Energy, Office of Basic Energy Sciences, Division of Materials Sciences and Engineering under Award DE-FG02-09ER46613.
