Coherent control of binary chemical reactions

Obiettivo

Coherent control is a method to manipulate the dynamics of a system on a pure quantum level by utilizing the interference effects. It takes advantage of the coherent nature of the laser light and the wave nature of matter in order to actively direct the dynamics of the system towards the desired final state. Over the past decade coherent control employing femtosecond laser pulses has experimentally been demonstrated for a variety of molecular processes.
However, all these processes were unimolecular - no coherent control of any binary reaction has experimentally been proved yet. The main goal of the project is to investigate the possibility of femtosecond coherent control of a binary chemical reaction in the high temperature regime. We propose to combine synergistically the most advanced methods of the electronic structure theory, quantum dynamics in a laser field, and optimal control theory to present a comprehensive
study of nonadiabatic molecular reactive dynamics in laser fields generated by femtosecond shaped pulses, and to illustrate the possibility to control coherently the outcome of the reactive collisions. The theory will be applied to the reaction between a magnesium atom and a hydrogen molecule. This molecular system features the most important aspects that we would like to explore, such as photo-induced reactivity or nonadiabaticity. Due to the favourable electronic properties of magnesium atom and hydrogen molecule we expect a relatively simple manifold of relevant potential energy surfaces, which will significantly reduce the complexity of the theoretical model and enable to carry out very accurate quantum-chemical and dynamical calculations to draw quantitative conclusions about the dynamics and laser control. Our theoretical results will be confronted with several experimental findings already published, and with the new data from the planned experiment on coherent binary collisions carried out by Dr. Zohar Amitay’s group in Haifa.
