Developments in the Coherent Control of Collisional Processes

Experimental and theoretical studies of the Coherent Control of unimolecular processes has seen spectacular growth over the last two decades. By contrast, Coherent Control of collisional processes remains a significant challenge. We describe: (1) the entanglement requirement for fixed energy scattering that makes controlled collisional experiments difficult, (2) demonstrate a viable theoretical proposal for control of collision induced ionization, and (3) introduce a time dependent approach that provides a new direction that bypasses entanglement requirements for collisional control. Applications to attosecond scenarios are computationally examined and shown to provide excellent control in the particular cases examined.
