1. Real time quantum dynamics in systems with many degrees of freedom ACS PRF Grant # AC6 PI: Eli Pollak, Chemical Physics Dept. Weizmann Institute of Science
New semiclassical initial value methods were invented for solution of electronic transitions in complex media. First examples with up to 100 degrees of freedom are for the spin boson problem:
thermal bath f2 f2 D e f1 f1
thermal bath
Time dependent population in
an asymmetric spin boson problem.
semiclassical zero-th order and 1-st
Order solution gives exact answer.
Solution feasible due to new f
formulation developed under this
grant.
