Reducing vortex density in superconductors using the ratchet effect
Choongseop Lee, Boldizsar Janko, Imre Derenyi +1
A serious obstacle that impedes the application of low and high temperature superconductor (SC) devices is the presence of trapped flux. Flux lines or vortices are induced by field…

Ratchet Effect in Surface Electromigration: Smoothing Surfaces by an ac Field
Imre Derenyi, Choongseop Lee, Albert-Laszlo Barabasi
We demonstrate that for surfaces that have a nonzero Schwoebel barrier the application of an ac field parallel to the surface induces a net electro- migration current that points i…
