Several years ago, we developed a formulation of the time-dependent Schrodinger equation (TDSE) using complex-valued classical trajectories.
The method has a number of appealing features:
  1. it has a simple and rigorous derivation from the TDSE with a precisely formulated approximation; 
  2. it treats classically allowed and classically forbidden processes on the same footing;
  3. it allows the introduction of arbitrary time-dependent external fields into the dynamics seamlessly and rigorously.
This talk will have three parts: 
  1. A review of the method and previous applications, including to barrier transmission, bound state dynamics and nonadiabatic dynamics;
  2. Two new methodological advances that open the door to multidimensional systems and long time dynamics, respectively;
  3. Applications made possible by these new advances, including long time wavepacket revivals and preliminary results on strong field attosecond tunneling ionization.
