Long-time signatures of short-time dynamics in decaying quantum-chaotic systems
T. Gorin, D. F. Martinez, H. Schomerus
We analyze the decay of classically chaotic quantum systems in the presence of fast ballistic escape routes on the Ehrenfest time scale. For a continuous excitation process, the fo…
Localization properties of driven disordered one-dimensional systems
Dario F. Martinez, Rafael A. Molina
We generalize the definition of localization length to disordered systems driven by a time-periodic potential using a Floquet-Green function formalism. We study its dependence on t…
Delocalization induced by low-frequency driving in disordered superlattices
Dario F. Martinez, Rafael A. Molina
We study the localization properties of disordered semiconductor superlattices driven by ac-fields. The localization length of the electrons in the superlattice increases when the…
High-order Harmonic Generation and Dynamic Localization in a driven two-level system, a non-perturbative solution using the Floquet-Green formalism
D. F. Martinez
We apply the Floquet-Green operator formalism to the case of a harmonically-driven two-level system. We derive exact expressions for the quasi-energies and the components of the Fl…
Transmission Properties of the oscillating delta-function potential
D. F. Martinez, L. E. Reichl
We derive an exact expression for the transmission amplitude of a particle moving through a harmonically driven delta-function potential by using the method of continued-fractions…
