Screw photon-like (3+1)-solitons in extended electrodynamics

Screw Photon-like (3+1)-Solitons in Extended Electrodynamics

This paper aims to present explicit photon-like (3+1) spatially finite soliton solutions of screw type to the vacuum field equations of Extended Electrodynamics (EED) in relativistic formulation. We begin with emphasizing the need for spatially finite soliton modelling of microobjects. Then we briefly comment the properties of solitons and photons and recall some facts from EED. Making use of t...

Ultra- Relativistic Solitons with Opposing Behaviors in Photon Gas Plasma

We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...

Photon-number squeezing in circuit quantum electrodynamics.

A superconducting single-electron transistor (SSET) coupled to an anharmonic oscillator, e.g., a Josephson junction-L-C circuit, can drive the latter to a nonequilibrium photon-number distribution. By biasing the SSET at the Josephson quasiparticle cycle, cooling of the oscillator as well as a laserlike enhancement of the photon number can be achieved. Here, we show that the cutoff in the quasi...

Special Session 31: Nonlinear Waves and Solitons

The strongly coupled nonlinear Schr odinger equations are studied numerically to gain insight into an increasingly complex family of collision interactions. Speci cally, the case of apparent repulsion between soliton solutions are considered in terms of phase velocity, relative shift, and apparent trajectory. Both elastic and inelastic collisions are discussed. −→∞ ∞←− anisotropic e ects on por...
