Ginzburg-Landau theory of the superheating field anisotropy of layered superconductors [PDF]

, 2016
We investigate the effects of material anisotropy on the superheating field of layered superconductors. We provide an intuitive argument both for the existence of a superheating field, and its dependence on anisotropy, for $\ensuremath{\kappa ...

Writing and deleting skyrmions with electric fields in a multiferroic heterostructure

Physical Review Research, 2021
Magnetic skyrmions are topological spin textures that can be used as information carriers for the next-generation information storage and processing. The electric-field controlling of skyrmions in such devices is essential but remains technologically ...

Zeeman field induced topological phase transitions in triplet superconductors [PDF]

, 2014
We develop a general Ginzburg-Landau theory which describes the effect of a Zeeman field on the superconducting order parameter in triplet superconductors.

Ginzburg-Landau theory of type II superconductors in magnetic field [PDF]

, 2009
Thermodynamics of type II superconductors in electromagnetic field based on the Ginzburg - Landau theory is presented. The Abrikosov flux lattice solution is derived using an expansion in a parameter characterizing the "distance" to the superconductor ...

Ginzburg-Landau theory of a trapped Fermi gas with a BEC-BCS crossover

, 2009
The Ginzburg-Landau theory of a trapped Fermi gas with a BEC-BCS crossover is derived by the path-integral method. In addition to the standard Ginzburg-Landau equation, a second equation describing the total atom density is obtained.

Supersymmetric Chern-Simons Theory and Supersymmetric Quantum Hall Liquid [PDF]

, 2006
We develop a supersymmetric extension of Chern-Simons theory and Chern-Simons-Landau-Ginzburg theory for supersymmetric quantum Hall liquid. Supersymmetric counterparts of topological and gauge structures peculiar to the Chern-Simons theory are inspected

(0,2) Landau-Ginzburg Theory

, 1993
A large class of (0,2) Calabi-Yau $\sigma$-models and Landau-Ginzburg orbifolds are shown to arise as different ``phases'' of supersymmetric gauge theories. We find a phenomenon in the Landau-Ginzburg phase which may enable one to understand which Calabi-
