Research GroupQuantum Theory Project (Chemical Physics)
Research InterestResearch interests include: Development of novel, rigorous, computationally tractable theory of molecular energetics and dynamics.
- Explicitly time-dependent theory beyond the adiabatic approximation for the study of molecular processes and atomic collisions
- Application of such theory to the study of elementary chemical reactions, such as electron transfer (intra - and intermolecular), energy transfer, and rearrangements
- Application to first principles calculations of rate constants for elementary gas phase reactions
- Application to the interaction of molecular systems with external fields, such as intense laser fields
- Application to the study of optical and conduction properties of polymeric systems
- Development and application of Green's function or propagator methods to the theoretical study of molecular spectroscopy
