Solitary waves in a discrete nonlinear Dirac equation [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2015
In the present work, we introduce a discrete formulation of the nonlinear Dirac equation in the form of a discretization of the Gross-Neveu model. The motivation for this discrete model proposal is both computational (near the continuum limit) and theoretical (using the understanding of the anti-continuum limit of vanishing coupling).

Global Strong Solutions to Some Nonlinear Dirac Equations in Super-Critical Space

open access: yesAbstract and Applied Analysis, 2013
We study the initial value problem of some nonlinear Dirac equations which are Lmℝ critical. Corresponding to the structure of nonlinear terms, global strong solutions can be obtained in different Lebesgue spaces by using solution representation formula.

A SHOCK LAYER ARISING AS THE SOURCE TERM COLLAPSES IN THE P(X)-LAPLACIAN EQUATION

open access: yesПроблемы анализа, 2020
We study the Cauchy–Dirichlet problem for the p(x)-Laplacian equation with a regular finite nonlinear minor term. The minor term depends on a small parameter ε > 0 and, as ε → 0, converges weakly* to the expression incorporating the Dirac delta function,

Fluid-electromagnetic helicities and knotted solutions of the fluid-electromagnetic equations

open access: yesJournal of High Energy Physics, 2022
In this paper we consider an Euler fluid coupled to external electromagnetism. We prove that the Hopfion fluid-electromagnetic knot, carrying fluid and electromagnetic (EM) helicities, solves the fluid dynamical equations as well as the Abanov Wiegmann ...

Construction of the Pauli-Villars-regulated Dirac vacuum in electromagnetic fields [PDF]

open access: yes, 2012
Using the Pauli-Villars regularization and arguments from convex analysis, we construct solutions to the classical time-independent Maxwell equations in Dirac's vacuum, in the presence of small external electromagnetic sources. The vacuum is not an empty

Gauge Invariance of Nonlinear Klein-Gordon

open access: yesPositron, 2013
We have discussed the gauge invariance of nonlinear Klein-Gordon equation which describes the interaction of electromagnetic initially proposed by Hermann Weyl. The construction of nonlinear Klein-Gordon itself is formulated by two classical conservation

Perturbation method for particlelike solutions of Einstein-Dirac equations

open access: yes, 2009
The aim of this work is to prove by a perturbation method the existence of solutions of the coupled Einstein-Dirac equations for a static, spherically symmetric system of two fermions in a singlet spinor state. We relate the solutions of our equations to

Linear and nonlinear photonic Jackiw-Rebbi states in waveguide arrays [PDF]

open access: yes, 2017
We study analytically and numerically the optical analogue of the Jackiw-Rebbi states in quantum field theory. These solutions exist at the interface of two binary waveguide arrays which are described by two Dirac equations with opposite sign masses.

Spinor solitons in one-dimensional and planar nonlinear Dirac equations

open access: yesPartial Differential Equations in Applied Mathematics
This article investigates nonlinear Dirac equations (NLD) with cubic-type nonlinearities, that is, vector and scalar self-interaction nonlinearities. We present analytical solutions of gap-solitons, which are self-localised, moving or quiescent pulses ...
