Aharonov–Bohm Effect for Cooper Pairs in Kerr Spacetime: Gravitomagnetic Phase Shifts From Frame Dragging

Annalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The unification of quantum mechanics and general relativity remains a central problem in fundamental physics. Here, we study the gravitomagnetic Aharonov–Bohm (AB) effect for Cooper pairs in Kerr spacetime. Frame‐dragging by a rotating black hole (BH) generates an effective vector potential through the off‐diagonal metric term gtϕ$g_{t\phi }$,

Mesoscale Domain Evolution Mechanism during Alternating Current (AC) Poling of Relaxor Ferroelectrics

Advanced Functional Materials, Volume 36, Issue 56, 13 July 2026.
Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...

Effective Hamiltonian and generalized Ginzburg–Landau theory

, 1991
We propose an effective Hamiltonian for the Ginzburg–Landau theory of a superconductor at rest. This yields the ordinary, and a time-dependent generalized Ginzburg–Landau theory.

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.

Order of superconductive phase transition

Condensed Matter Physics, 2005
On the occasion of Reinhard Folk's 60th birthday, I give a brief review of the theoretical progress in understanding the critical properties of superconductors. I point out the theoretical difficulties in finding a second-order transition in the Ginzburg-

Numerical studies of superfluids and superconductors [PDF]

, 2001
In this thesis we demonstrate the power of the Gross-Pitaevskii and the time-dependent Ginzburg-Landau equations by numerically solving them for various fundamental problems related to superfluidity and superconductivity.

Landau-Ginzburg string vacua

, 1994
We investigate a class of (2,2) supersymmetric string vacua which may be represented as Landau--Ginzburg theories with a quasihomogeneous potential which has an isolated singularity at the origin. There are at least three thousand distinct models in this

Higher-matter and Landau-Ginzburg theory of higher-group symmetries

SciPost Physics
Higher-matter is defined by higher-representation of a symmetry algebra, such as the $p$-form symmetries, higher-group symmetries or higher-categorical symmetries.
