Nambu-Type Generalization of the Dirac Equation [PDF]

open access: yes, 1996
Nonlinear generalization of the Dirac equation extending the standard paradigm of nonlinear Hamiltonians is discussed. ``Faster-than-light telegraphs" are absent for all theories formulated within the new framework.

Integration of the negative order Nonlinear Schr¨odinger Equation with self-consistent source

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
This paper focuses on the integrability properties of the negative-order nonlinear Schro¨dinger equation with a source. The source consists of the combination of the eigenfunctions of the corresponding spectral problem for the Dirac system which has not

A New Super Extension of Dirac Hierarchy

open access: yesAbstract and Applied Analysis, 2014
We derive a new super extension of the Dirac hierarchy associated with a 3×3 matrix super spectral problem with the help of the zero-curvature equation. Super trace identity is used to furnish the super Hamiltonian structures for the resulting nonlinear

Uniformly accurate numerical schemes for the nonlinear Dirac equation in the nonrelativistic limit regime [PDF]

open access: yes, 2016
We apply the two-scale formulation approach to propose uniformly accurate (UA) schemes for solving the nonlinear Dirac equation in the nonrelativistic limit regime.

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

The Dirac equation as a linear tensor equation for one component

open access: yesEuropean Physical Journal C: Particles and Fields
The Dirac equation is one of the most fundamental equations of modern physics. It is a spinor equation, but some tensor equivalents of the equation were proposed previously.

Integration of the Loaded Negative Order Nonlinear Schrodinger Equation in the Class of Periodic Functions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
In this paper, we consider the loaded negative order nonlinear Schrodinger equation (NSE) in the class of periodic functions. It is shown that the loaded negative order nonlinear Schrodinger equation can be integrated by the inverse spectral problem ...

Singular traveling wave solutions for Boussinesq equation with power law nonlinearity and dual dispersion

open access: yesAdvances in Difference Equations, 2019
In this paper we study the Boussinesq equation with power law nonlinearity and dual dispersion which arises in fluid dynamics. A particular kind of product of distributions is introduced and applied to solve non-smooth solutions of this equation.

Third-order nonlinear Hall effect in two-dimensional Dirac systems

open access: yesNew Journal of Physics, 2023
We theoretically investigate the third-order nonlinear Hall effect by employing the quantum kinetic equation and present an analytic formula for the third-order harmonic conductivity, where the intraband and the mixed inter-band contributions caused by ...

Nonlinear Dirac equations and nonlinear gauge transformations

open access: yes, 2003
Nonlinear Dirac equations (NLDE) are derived through a group N^2 of nonlinear (gauge) transformation acting in the corresponding state space. The construction generalises a construction for nonlinear Schr dinger equations. To relate N^2 with physically motivated principles we assume: locality (i.e. it contains no explicit derivative and no derivatives
