Towards laser control of open quantum systems: memory effects

Abstract: Laser control of Open Quantum Systems (OQS) is a challenging issue as compared to its counterpart in isolated small size molecules, basically due to very large numbers of degrees of freedom to be accounted for. Such a control aims at appropriately optimizing decoherence processes of a central two-level system (a given vibrational mode, for instance) towards its environmental bath (including, for instance, all other normal modes). A variety of applications could potentially be envisioned, either to preserve the… Show more

“…different initial and target states). The field-free energy gap is 0.33 eV and the optimal fields induce different Stark shifts in a range of about 0.25-0.65 eV, so that the instantaneous resonance frequency ω 0 (t) moves with respect to the spectral density peaks, with its expected consequences on non-Markovianity [29,30]. Obviously, different initial states, with different field-free energy gaps (characterizing heterojunction models with different inner-fragment distances [38]) will result into different control parameters, but still with transposable strategies and generic enough results.…”

“…Other non-Markovianity signatures refer to a re-amplification of the volume of accessible states during the decay process [11], the detection of a negative canonical decay rate [12,13], or a non-monotonous time evolution of the system von Neumann entropy [14]. Even more importantly, the role of transitory information back flow in externally controlled dynamics remains an open issue and an active research area [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”
