Pulse-driven near-resonant quantum adiabatic dynamics: lifting of quasi-degeneracy
L. P. Yatsenko, S. Guerin, H. R. Jauslin
We study the quantum dynamics of a two-level system driven by a pulse that starts near-resonant for small amplitudes, yielding nonadiabatic evolution, and induces an adiabatic evol…
Quantum averaging and resonances: two-level atom in a one-mode quantized field
M. Amniat-Talab, S. Guerin, H. R. Jauslin
We construct a non-perturbative approach based on quantum averaging combined with resonant transformations to detect the resonances of a given Hamiltonian and to treat them. This a…
Optimized time-dependent perturbation theory for pulse-driven quantum dynamics in atomic or molecular systems
D. Daems, S. Guérin, H. R. Jauslin +2
We present a time-dependent perturbative approach adapted to the treatment of intense pulsed interactions. We show there is a freedom in choosing secular terms and use it to optimi…
Reaching optimally oriented molecular states by laser kicks
D. Sugny, A. Keller, O. Atabek +4
We present a strategy for post-pulse orientation aiming both at efficiency and maximal duration within a rotational period. We first identify the optimally oriented states which fu…
Unitary time-dependent superconvergent technique for pulse-driven quantum dynamics
D. Daems, A. Keller, S. Guérin +2
We present a superconvergent Kolmogorov-Arnold-Moser type of perturbation theory for time-dependent Hamiltonians. It is strictly unitary upon truncation at an arbitrary order and n…
