Molecular Spectroscopy and Quantum Dynamics

After reviewing molecular quantum dynamics induced by the interaction with electromagnetic field and the most common semiclassical approximations to quantum dynamics, we explain details of the thawed Gaussian approximation and its variants. Next, we discuss the time-dependent approach to steady-state and time-resolved electronic spectroscopy ...

Quantum Molecular Dynamics Computing

First-principles molecular dynamics (FPMD) codes are used by biologists, chemists, and physicists to calculate interactions between atoms and molecules. These codes are based on quantum mechanics modeling and many elements of these computations are proportional to the square or cube of the system size. Thus, with traditional algorithms, the ...
