Decoherence in quantum cavities: Environmental erasure of carpet-type structures

Quantum carpets in a leaky box: Poincaré's recurrences in the continuous spectrum

“…However, tunneling alone is not capable of producing complete decoherence. Nevertheless, the presented simple, solvable model shares many features of the effective decoherence models [24][25][26], or more elaborate numerical investigations [27][28][29]. An additional advantage is that all physical quantities, such as the energies and lifetimes of resonant states that are are functions of V o , have a clear physical interpretation.…”

“…There are proposals to use the distortion of quantum carpets to study decoherence processes [24][25][26]. The presented model can also be used for that purpose.…”

“…The derived model has effectively only one free parameter controlling the strength of decoherence, instead of the abstract parameter used in Refs. [24][25][26].…”
