2D Dilaton-Maxwell Gravity as a Fixed Point of the Renormalization Group

open access: yes, 1993
A general model of dialton-Maxwell gravity in two dimensions is investigated. The corresponding one-loop effective action and the generalized $\beta$-functions are obtained. A set of models that are fixed points of the renormalization group equations are

On the frequency dependence of viscoelastic material characterization with intermittent-contact dynamic atomic force microscopy: avoiding mischaracterization across large frequency ranges

open access: yesBeilstein Journal of Nanotechnology, 2020
Atomic force microscopy (AFM) is a widely use technique to acquire topographical, mechanical, or electromagnetic properties of surfaces, as well as to induce surface modifications at the micrometer and nanometer scale. Viscoelastic materials, examples of

Duality, Generalized Global Symmetries and Jet Space Isometries

open access: yesUniverse, 2021
We revisit universal features of duality in linear and nonlinear relativistic scalar and Abelian 1-form theories with single or multiple fields, which exhibit ordinary or generalized global symmetries.

Charged Nielsen-Olesen vortices from a Generalized Abelian Chern-Simons-Higgs Theory [PDF]

open access: yes, 2013
We consider a generalization of abelian Chern-Simons-Higgs model by introducing a nonstandard kinetic term. In particular we show that the Bogomolnyi equations of the abelian Higgs theory may be obtained, being its solutions Nielsen-Olesen vortices with ...

Fundamental Solutions of the Equations of Classical and Generalized Heat Conduction Models

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
This article presents the mathematical formulations of transient heat conduction problems corresponding to the models of classical heat conduction using the Fourier law and generalized heat conduction based on the Cattaneo–Vernotta–Lykov law (Maxwell ...

Lifshitz effects on holographic p-wave superfluid

open access: yesPhysics Letters B, 2015
In the probe limit, we numerically build a holographic p-wave superfluid model in the four-dimensional Lifshitz black hole coupled to a Maxwell-complex vector field.

Self-dual Vortices in the Generalized Abelian Higgs Model with Independent Chern-Simons Interaction

open access: yes, 1992
Self-dual vortex solutions are studied in detail in the generalized abelian Higgs model with independent Chern-Simons interaction. For special choices of couplings, it reduces to a Maxwell-Higgs model with two scalar fields, a Chern-Simons-Higgs model ...

Stable Equilibrium Based on L\'evy Statistics: A Linear Boltzmann Equation Approach [PDF]

open access: yes, 2003
To obtain further insight on possible power law generalizations of Boltzmann equilibrium concepts, a stochastic collision model is investigated. We consider the dynamics of a tracer particle of mass $M$, undergoing elastic collisions with ideal gas ...

A new generalized fractional Maxwell model of dielectric relaxation

open access: yesChinese Journal of Physics, 2017
Abstract The polarization of dielectric materials in electric field lags behind the external field and the relaxation losses energy. In this paper, the relaxation characteristics of the fractional models established by using a fractional differential operator (cap-resistor) are analyzed.
