Instantons revisited: dynamical tunnelling and resonant tunnelling
Tunnelling dynamical tunnelling resonant tunnelling instantons semiclassical methods Wick rotation complex time
2010/4/8
Starting from trace formulae for the tunnelling splittings (or decay rates) analytically continued in the complex time domain, we obtain explicit semiclassical expansions in terms of complex trajector...

Variational Ground State Approach for A Tunnelling Exciton Coupled to Phonons
Hamiltonian Ground state approximation Vacuum state
2010/4/9
In this paper a variational study of a tunnelling exciton (Frenkel exciton) coupled to an arbitrary number of phonon modes is presented. The results of our model are presented both for weak non-adiaba...
