Non-Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films. [PDF]

Adv Mater
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Reliability of the Ginzburg–Landau Theory in the BCS-BEC Crossover by Including Gaussian Fluctuations for 3D Attractive Fermions

Condensed Matter, 2021
We calculate the parameters of the Ginzburg–Landau (GL) equation of a three-dimensional attractive Fermi gas around the superfluid critical temperature.

Solving Nonlinear Fractional Models in Superconductivity Using the q-Homotopy Analysis Transform Method

Journal of Mathematics, 2023
The Ginzburg–Landau (GL) equation and the Ginzburg–Landau couple system are important models in the study of superconductivity and superfluidity. This study describes the q-homotopy analysis transform method (q-HATM) as a powerful technique for solving ...

Asymptotic behavior of random coupled Ginzburg–Landau equation driven by colored noise on unbounded domains

Advances in Difference Equations, 2021
In this paper, a random coupled Ginzburg–Landau equation driven by colored noise on unbounded domains is considered, in which the nonlinear term satisfies a local Lipschitz condition.

Ginzburg-Landau effective action for a fluctuating holographic superconductor

Journal of High Energy Physics, 2021
Under holographic prescription for Schwinger-Keldysh closed time contour for non-equilibrium system, we consider fluctuation effect of the order parameter in a holographic superconductor model.

Instability of Ginzburg-Landau Vortices on Manifolds [PDF]

, 2011
We investigate two settings of Ginzburg-Landau posed on a manifold where vortices are unstable. The first is an instability result for critical points with vortices of the Ginzburg-Landau energy posed on a simply connected, compact, closed 2-manifold ...

Small Landau-Ginzburg theories

Journal of High Energy Physics, 2019
We classify (0,2) Landau-Ginzburg theories that can flow to compact IR fixed points with equal left and right central charges strictly bounded by 3. Our result is a (0,2) generalization of the ADE classification of (2,2) Landau-Ginzburg theories that ...

Ginzburg-Landau Approach to Holographic Superconductivity [PDF]

, 2014
We construct a family of minimal phenomenological models for holographic superconductors in d=4+1 AdS spacetime and study the effect of scalar and gauge field fluctuations. By making a Ginzburg-Landau interpretation of the dual field theory, we determine

On the Analyticity for the Generalized Quadratic Derivative Complex Ginzburg-Landau Equation

Abstract and Applied Analysis, 2014
We study the analytic property of the (generalized) quadratic derivative Ginzburg-Landau equation (1/2⩽α⩽1) in any spatial dimension n⩾1 with rough initial data.
