Forced oscillations for singular dynamical systems with an application to the restricted three body problem
We consider forced dynamical systems with two degrees of freedom having singular potentials and we prove existence of infinitely many classical (noncollision) periodic solutions. These solutions have a prescribed rotation ...
Initial thermalization of photoexcited carriers in GaAs studied by femtosecond luminescence spectroscopy
(AMERICAN PHYSICAL SOC, 1991)
Relaxation of a nonequilibrium distribution of electrons and holes in GaAs following femtosecond photoexcitation is investigated via spectrally and time-resolved luminescence. A rapid onset of luminescence over a broad ...
