Journal Article
Pulse-driven quantum dynamics beyond the impulsive regime (15 pages)
TL;DR: In this paper, the Kolmogorov-Arnold-Moser (KARM) method is compared with other time-dependent perturbation methods, and it is shown that the KARM method performs better owing to both the superexponential character of correction terms and the possibility to optimize the accuracy of a given level of approximation.
Journal ArticleDOI
Collective strong coupling in a plasmonic nanocavity.
TL;DR: This work describes in detail collective strong coupling to a plasmonic nanocavity and observes that the Rabi splitting can strongly deviate from the standard NeΔΩ1 law.
Journal ArticleDOI
Coherent destruction of tunneling in a six-dimensional model of NHD2: a computational study using the multi-configuration time-dependent Hartree method.
TL;DR: The multi-configuration time-dependent Hartree method is used to solve the time- dependent Schrödinger equation for a six-dimensional model of the molecule in interaction with an adiabatically turned on monochromatic laser field, in order to confirm the results obtained from this analysis.
Journal ArticleDOI
Optimized time-dependent perturbation theory for pulse-driven quantum dynamics in atomic or molecular systems
TL;DR: In this article, a time-dependent perturbative approach adapted to the treatment of intense pulsed interactions is presented. But it is only applicable to the case of superconvergent techniques.
Journal ArticleDOI
Adiabatic evolution for systems with infinitely many eigenvalue crossings
TL;DR: In this article, an adiabatic theorem adapted to models that present an instantaneous eigenvalue experiencing an infinite number of crossings with the rest of the spectrum was formulated and an upper bound on the leading correction terms with respect to the adiabiatic limit was given.
