RESEARCH INTERESTS

Currently, I am also exploring a general analytical technique for solving time-dependent operator equations through a succession of unitary integrations. Applications to laser-atom interactions and to the Bloch-Liouville equation for a (2j+1)-level system in time-dependent fields are of particular interest, along with current topics in nuclear magnetic resonance and quantum bits. The method has also been extended to dissipation and decoherence which is of great interest in quantum information and quantum computing.
