An extended Ginzburg-Landau description for superconductors

open access: yes, 2005
We give a straightforward generalization of the Ginzburg-Landau theory for superconductors where the scalar phase field is replaced by an antisymmetric Kalb-Ramond field. While the standard properties of superconductors are recovered for temperatures not

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

open access: yesAdvanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Article Review: Anomalous Meissner Effect in Multiband Superconductors

open access: yesAl-Kitab Journal for Pure Sciences
As a material transitions below its critical temperature, a defining characteristic of superconductivity is the Meissner effect, which is the removal of magnetic fields from the material.
