What is the semiclassical limit of non-Hermitian time evolution ?
à 11h en salle C. Brot
In recent work with E.M. Graefe we studied the semiclassical limit of non-Hermitian time evolution using coherent states and found that, contrary to what one would expect, the classical dynamics which emerges is not the complexified Hamiltonian one. Instead a combination between a Hamiltonian and a gradient vector field governs the dynamics. In this talk we will describe the geometry underlying the semicalssical limit and illustrate it with some examples.
