Fluxoids behavior in superconducting ladders

The optimal rubbling number of ladders, prisms and Möbius-ladders

A pebbling move on a graph removes two pebbles at a vertex and adds one pebble at an adjacent vertex. Rubbling is a version of pebbling where an additional move is allowed. In this new move, one pebble each is removed at vertices v and w adjacent to a vertex u, and an extra pebble is added at vertex u. A vertex is reachable from a pebble distribution if it is possible to move a pebble to that v...

Critical Behavior of Layered Superconducting Films in Parallel Magnetic Field

The equilibrium magnetization for layered superconducting films that experience a nonzero component, H‖, of magnetic field applied parallel to the layers is computed at temperatures and at perpendicular field components in the vicinity of the decoupling transition. A fermion analogy is exploited for this purpose, whereby it is found that the parallel magnetization shows an anomalous H ‖ tail at...

Explanation of magnetic behavior in Ru-based superconducting ferromagnets

Josephson behavior of phase-slip lines in wide superconducting strips.

Phase-slip lines can be viewed as dynamically created Josephson junctions in a homogeneous superconducting film. In contrast to phase-slip centers, phase-slip lines occur in wide superconducting strips, where the order parameter may vary in two dimensions. We investigated phase-slip lines in two different materials using several methods. We observed Shapiro steps under microwave radiation, whic...
