Nonlinear Cnoidal Waves and Formation of Patterns and Coherent Structures in Intense Charged Particle Beams
Stephan I. Tzenov, Anton A. Volodin
The longitudinal dynamics of an intense high energy beam moving in a resonator cavity has been studied in some detail. Through the method of separation of variables and its obvious…
Quantum Description of Free Electron Laser Radiation and Nonlinear Amplitude Equations
Stephan I. Tzenov, Zhichu Chen
A relativistic quantum mechanical model to describe the quantum FEL dynamics has been developed. Neglecting the spin of electrons in the impacting beam, this model is based on the…
Dispersion Properties, Nonlinear Waves and Birefringence in Classical Nonlinear Electrodynamics
Stephan I. Tzenov, Klaus M. Spohr, Kazuo A. Tanaka
Using the very basic physics principles, we have studied the implications of quantum corrections to classical electrodynamics and the propagation of electromagnetic waves and pulse…
Relativistic Nonlinear Whistler Waves in Cold Magnetized Plasmas
Stephan I. Tzenov
Starting from the Vlasov-Maxwell equations describing the dynamics of various species in a quasi-neutral plasma immersed in an external solenoidal magnetic field and utilizing a te…
Nonlinear Waves and Coherent Structures in Quasi-neutral Plasmas Excited by External Electromagnetic Radiation
Stephan I. Tzenov
Starting from the Vlasov-Maxwell equations describing the dynamics of various species in a quasi-neutral plasma, an exact relativistic hydrodynamic closure for a special type of wa…
Nonlinear Waves and Coherent Structures in the Quantum Single-Wave Model
Stephan I. Tzenov, Kiril B. Marinov
Starting from the von Neumann-Maxwell equations for the Wigner quasi-probability distribution and for the self-consistent electric field, the quantum analog of the classical single…
Nonlinear Density Waves in the Single-Wave Model
Kiril B. Marinov, Stephan I. Tzenov
The single-wave model equations are transformed to an exact hydrodynamic closure by using a class of solutions to the Vlasov equation corresponding to the waterbag model. The warm…
Whistleron Gas in Magnetized Plasmas
Salvatore De Martino, Mariarosaria Falanga, Stephan I. Tzenov
We have studied the nonlinear dynamics of whistler waves in magnetized plasmas. Since plasmas and beam-plasma systems considered here are assumed to be weakly collisional, the poin…
