Vibrational effects on quantum diffusion in kicked rotors.

Published 2006 .
Written in English.

About the Book

The vibrational effects on the coherent control of quantum diffusion are investigated in kicked rotors. In particular, the model employed is a vibro-rotating diatomic molecule, where the vibrations are described by a harmonic potential. The main control scenario under study is periodic field reversal, although initial state coherence effects are also briefly examined. Quantum diffusion is monitored through the kick-averaged rotational energy as a function of the initial vibrational state and the quantum parameter tau (related to the kicking period) for different molecules. It is found that quantum diffusion is highly sensitive to changes in the aforementioned variables. Furthermore, the results obtained support the idea that enhancement or suppression of quantum diffusion, in the periodic field reversal scenario, is related to quantum resonances rather than a vibro-rotational energy transfer mechanism.
