Two-dimensional Fireballs as a Lagrangian Ermakov System
Fernando Haas
The equations of motion for the variance of strictly one-dimensional or two-dimensional non-relativistic fireballs are derived, from the hydrodynamic equations for an ideal, struct…
Dynamics of antiproton plasma in a time-dependent harmonic trap
Luiz Gustavo F. Soares, Fernando Haas
An antiproton plasma confined in a quasi-1D device is described in terms of a self-consistent fluid formulation using a variational approach. Unlike previous treatments, the use of…
New nonlinear structures in a degenerate one-dimensional electron gas
S. Ghosh, N. Chakrabarti, F. Haas
The collective dynamics of nonlinear electron waves in an one-dimensional degenerate electron gas is treated using the Lagrangian fluid approach. A new class of solutions with a no…
Wave dispersion derived from the square-root Klein-Gordon-Poisson system
Fernando Haas
Recently there has been great interest around quantum relativistic models for plasmas. In particular striking advances have been obtained by means of the Klein-Gordon-Maxwell syste…
Time-Dependent Gaussian Solution for the Kostin Equation around Classical Trajectories
F. Haas, J. M. F. Bassalo, D. G. da Silva +2
The structure of time-dependent Gaussian solutions for the Kostin equation in dissipative quantum mechanics is analyzed. Expanding the generic external potential near the center of…
Variational Method for the Three-Dimensional Many-Electron Dynamics of Semiconductor Quantum Wells
F. Haas
The three-dimensional nonlinear dynamics of an electron gas in a semiconductor quantum well is analyzed in terms of a self-consistent fluid formulation and a variational approach.…
