The role of tunneling in the ionization of atoms by ultrashort and intense laser pulses
Gabriel M. Lando
Classically allowed transport is shown to compete with quantum tunneling during the ionization of atoms by ultrashort and intense laser pulses, despite Keldysh parameters smaller t…
Complexified phase spaces, initial value representations, and the accuracy of semiclassical propagation
Gabriel M. Lando
Using phase-space complexification, an Initial Value Representation (IVR) for the semiclassical propagator in position space is obtained as a composition of inverse Segal-Bargmann…
Quantum-Chaotic Evolution Reproduced from Effective Integrable Trajectories
Gabriel M. Lando, Alfredo M. Ozorio de Almeida
Classically integrable approximants are here constructed for a family of predominantly chaotic periodic systems by means of the Baker-Hausdorff-Campbell formula. We compare the evo…
Semiclassical evolution in phase space for a softly chaotic system
Gabriel M. Lando, Alfredo M. Ozorio de Almeida
An initial coherent state is propagated exactly by a kicked quantum Hamiltonian and its associated classical stroboscopic map. The classical trajectories within the initial state a…
Quantum revival patterns from classical phase-space trajectories
Gabriel M. Lando, Raúl O. Vallejos, Gert-Ludwig Ingold +1
A general semiclassical method in phase space based on the final value representation of the Wigner function is considered that bypasses caustics and the need to root-search for cl…
