Classical trajectories: A powerful tool for solving tunneling problems

Sels, Dries; Brosens, Fons; Magnus, Wim - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 1, pp. 78-81

In the realm of Ehrenfest’s theorem, classical trajectories obeying Newton’s laws have been proven useful to construct explicit solutions to the time-dependent Wigner–Liouville equation. Whereas previous works have particularly focused on the initial distribution function as a vehicle...
