Dynamic Model and Phase Transitions for Liquid Helium

, 2008
This article presents a phenomenological dynamic phase transition theory -- modeling and analysis -- for superfluids. As we know, although the time-dependent Ginzburg-Landau model has been successfully used in superconductivity, and the classical ...

Landau ordering phase transitions beyond the Landau paradigm

Physical Review Research, 2020
Continuous phase transitions associated with the onset of a spontaneously broken symmetry are thought to be successfully described by the Landau-Ginzburg-Wilson-Fisher theory of fluctuating order parameters.

The supercurrent diode effect and nonreciprocal paraconductivity due to the chiral structure of nanotubes

Nature Communications, 2023
The phenomenon that critical supercurrents along opposite directions become unequal is called the supercurrent diode effect (SDE). It has been observed in various systems and can often be understood by combining spin-orbit coupling and Zeeman field ...

Topological Landau-Ginzburg Theory for Vortices in Superfluid $^4$He

, 1993
We propose a new Landau-Ginzburg theory for arbitrarily shaped vortex strings in superfluid $^4$He. The theory contains a topological term and directly describes vortex dynamics.

Spin Order in Paired Quantum Hall States [PDF]

, 2007
We consider quantum Hall states at even-denominator filling fractions, especially $\nu=5/2$, in the limit of small Zeeman energy. Assuming that a paired quantum Hall state forms, we study spin ordering and its interplay with pairing.

Vortex motion and the Hall effect in type-II superconductors: A time-dependent Ginzburg-Landau theory approach. [PDF]

Physical Review B (Condensed Matter), 1992
Vortex motion in type-II superconductors is studied starting from a variant of the time-dependent Ginzburg-Landau equations, in which the order-parameter relaxation time is taken to be complex.

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Towards Ginzburg–Landau Bogomolny Approach and a Perturbative Description of Superconducting Structures

Quantum Reports
The Bogomolny approach to the Ginzburg–Landau equations in the context of strong and semi-strong necessary conditions is formulated for various superconducting structures in a quasi-one-dimensional description, considering both flat and curved geometries.

Oscillatory magneto-convection under magnetic field modulation

Alexandria Engineering Journal, 2018
In this paper we investigate an oscillatory mode of nonlinear magneto-convection under time dependant magnetic field. The time dependant magnetic field consists steady and oscillatory parts.

Critical Exponents of the Superconducting Phase Transition

, 1995
We study the critical exponents of the superconducting phase transition in the context of renormalization group theory starting from a dual formulation of the Ginzburg-Landau theory. The dual formulation describes a loop gas of Abrikosov flux tubes which
