Nonlinear Dirac Equations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
We construct nonlinear extensions of Dirac's relativistic electron equation that preserve its other desirable properties such as locality, separability, conservation of probability and Poincaré invariance.

Nonlinear Dirac Equations, Monotonicity Formulas and Liouville Theorems. [PDF]

open access: yesCommun Math Phys, 2019
Abstract We study the qualitative behavior of nonlinear Dirac equations arising in quantum field theory on complete Riemannian manifolds. In particular, we derive monotonicity formulas and Liouville theorems for solutions of these equations. Finally, we extend our analysis to Dirac-harmonic maps with curvature term.

Local and global well-posedness for nonlinear Dirac type equations [PDF]

open access: yes, 2012
We investigate the local and global well-posedness of a variety of nonlinear Dirac type equations with null structure on R1+1. In particular, we prove global existence in L2 for a nonlinear Dirac equation known as the Thirring model. Local existence in

Nonlinear Dirac equation for graphene [PDF]

open access: yesKeldysh Institute Preprints, 2016
The possibility of introducing a nonlinear correction to the Dirac equation for graphene in order to adequately describe collective electronic phenomena is considered. In contrast to the other papers on this topic the interaction term includes the sum of the spinor components’ squares instead of their difference.

Constraining Non-linear Dirac Equations with Neutrino Oscillations [PDF]

open access: yesEPJ Web of Conferences, 2019
Considering the phenomenological studies of non-linear quantum models, we use an axiomatic approach to modify the Dirac Lagrangian. We apply constraints such as Hermiticity, locality, universality, etc to obtain various generic modified energy dispersion

Numerical methods for nonlinear Dirac equation [PDF]

open access: yesJournal of Computational Physics, 2013
This paper presents a review of the current state-of-the-art of numerical methods for nonlinear Dirac (NLD) equation. Several methods are extendedly proposed for the (1+1)-dimensional NLD equation with the scalar and vector self-interaction and analyzed in the way of the accuracy and the time reversibility as well as the conservation of the discrete ...
