Supersymmetry of FRW barotropic cosmologies
(2006)
"Barotropic FRW cosmologies are presented from the standpoint of nonrelativis-tic supersymmetry. First, we reduce the barotropic FRW system of diferential equations to simple harmonic oscillator diferential equations. ...
Traveling kinks in cubic nonlinear Ginzburg-Landau equations
(2012)
"Nonlinear cubic Euler-Lagrange equations of motion in the traveling variable are usually derived from Ginzburg-Landau free energy functionals frequently encountered in several fields of physics. Many authors considered ...
