Propagation of Wave Packets for Systems Presenting Codimension 1 Crossings (2001.07484v3)
Published 21 Jan 2020 in math.AP, math-ph, and math.MP
Abstract: We analyze the propagation of coherent states through general systems of pseudodifferential form associated with Hamiltonian presenting codimension one eigen-value crossings. In particular, we calculate precisely the non adiabatic effects of the crossing in terms of a transition operator.
