Ginzburg-Landau theory of noncentrosymmetric superconductors

, 2007
The data of temperature dependent superfluid density $n_s(T)$ in Li$_2$Pd$_3$B and Li$_2$Pt$_3$B [Yuan {\it et al.}, \phrl97, 017006 (2006)] show that a sudden change of the slope of $n_s (T)$ occur at slightly lower than the critical temperature ...

Different length scales for order parameters in two-gap superconductors : extended Ginzburg-Landau theory [PDF]

, 2011
Using the Ginzburg-Landau theory extended to the next-to-leading order we determine numerically the healing lengths of the two order parameters at the two-gap superconductor/normal metal interface.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Enhanced Ferroelectricity in Hf1−XZrXO2 Thin Films Through Ultrathin Mo Electrode Layer and Microwave Annealing

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 4, April 2026.
Uniform volumetric heating via microwave annealing combined with an ultrathin Mo interlayer enables low‐temperature crystallization of thin HZO films. Interfacial degradation and dead‐layer formation are suppressed, resulting in enlarged ferroelectric domains, uniform switching behavior, and a high remanent polarization of 45.2 μC/cm2 at 200°C.

Anisotropy of the upper critical field in MgB2: the two-gap Ginzburg-Landau theory

, 2005
The upper critical field in MgB2 is investigated in the framework of the two-gap Ginzburg-Landau theory. A variational solution of linearized Ginzburg-Landau equations agrees well with the Landau level expansion and demonstrates that spatial ...

Graph potentials and topological quantum field theories

Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract We introduce a new functional equation in birational geometry, whose solutions can be used to construct two‐dimensional topological quantum field theories (2d TQFTs), infinite‐dimensional in many interesting examples. The solutions of the equation give rise to a hierarchy of graph potentials, which, in the simplest setup, are Laurent ...

Classical {\it vs.}\ Landau-Ginzburg Geometry of Compactification

, 1992
We consider superstring compactifications where both the classical description, in terms of a Calabi-Yau manifold, and also the quantum theory is known in terms of a Landau-Ginzburg orbifold model.

Novel Lifshitz point for chiral transition in the magnetic field

Physics Letters B, 2015
Based on the generalized Ginzburg–Landau theory, chiral phase transition is discussed in the presence of magnetic field. Considering the chiral density wave we show that chiral anomaly gives rise to an inhomogeneous chiral phase for nonzero quark-number ...

Ginzburg-Landau description of a class of non-unitary minimal models

Journal of High Energy Physics
It has been proposed that the Ginzburg-Landau description of the non-unitary conformal minimal model M (3, 8) is provided by the Euclidean theory of two real scalar fields with third-order interactions that have imaginary coefficients.
