We propose cyclic refrigeration in solid state, employing a gas of magnetic field vortices in a
type-II superconductor—also known as fluxons—as the cooling agent. Refrigeration cycles …

Ratchets formed from spatially asymmetric confining potentials can rectify an oscillatory
driving force and generate directed motion. Such devices can probe the fundamental nature …

With advances in fabrication technologies it is now possible to create precisely controlled
geometries and pinning landscapes for vortex matter in type-II superconductors. Here we …

We study the dynamics of vortices in an asymmetric (ie, consisting of triangular cells) ring
channel driven by an external ac current I in a Corbino setup. The asymmetric potential …

We numerically study superconducting vortices confined by an array of asymmetric funnels.
For driving in the easy direction, we find peaks in the depinning force at commensurate …

We look at three different kinds of systems, requiring quantum to classical description. The
first system is a quantum harmonic oscillator in general Gaussian states undergoing …

We study the rectification of vortex motion in an asymmetric ring channel in a Corbino setup.
With an applied ac current, the motion of vortices in the channel is rectified by the …

Vortex pinning in superconductors with artificially introduced pinning arrays provides a
controllable method for studying periodic systems moving in the presence of a periodic …
