Modeling small-angle scattering data of porous and/or bicontinuous structures in <i>n</i> dimensions. [PDF]
J Appl CrystallogrA small‐angle scattering fitting function is derived for porous materials with arbitrary fractal dimension. It includes a correlation peak and a power law at higher q.Fractal structures are often observed in small‐angle scattering experiments where a simple power law q−α describes the scattering intensity over many orders of magnitude.

Mean string field theory: Landau-Ginzburg theory for 1-form symmetries
SciPost Physics, 2022 By analogy with the Landau-Ginzburg theory of ordinary zero-form symmetries, we introduce and develop a Landau-Ginzburg theory of one-form global symmetries, which we call mean string field theory.

Microscopic derivation of Ginzburg-Landau theories for hierarchical quantum Hall states
SciPost Physics, 2020 We propose a Ginzburg-Landau theory for a large and important part of the abelian quantum Hall hierarchy, including the prominently observed Jain sequences.

Excited States of “Elementary” Particles in Gauge-Higgs Theories [PDF]
EPJ Web of Conferences, 2022 We show that the gauge and scalar fields which surround static ions in the Ginzburg-Landau model of superconductivity have a spectrum of excitations which are potentially observable.

Superconductors with a Topological Gap
Condensed Matter, 2023 I review a new superconductivity mechanism in which the gap is opened through a topological mechanism and not through the Landau mechanism of spontaneous symmetry breaking.

Dual Variational Formulations for a Large Class of Non-Convex Models in the Calculus of Variations
Mathematics, 2022 This article develops dual variational formulations for a large class of models in variational optimization. The results are established through basic tools of functional analysis, convex analysis and duality theory.

Two-Dimensional Discommensurations: An Extension to McMillan’s Ginzburg–Landau Theory
Condensed Matter, 2023 Charge density waves (CDWs) profoundly affect the electronic properties of materials and have an intricate interplay with other collective states, like superconductivity and magnetism.

On fluxes in the 19 Landau-Ginzburg model
Journal of High Energy Physics, 2023 In this paper we present a large class of flux backgrounds and solve the shortest vector problem in type IIB string theory on an orientifold of the 19 Landau-Ginzburg model.

The equation of state for metal-doped ferroelectrics within the Weiss model
Journal of Advanced Dielectrics, 2022 This paper presents a theoretical model for describing the thermodynamic properties of doped ferroelectric crystals based on a modified Weiss mean-field approach.
