Multiconfigurational quantum propagation with trajectory-guided generalized coherent states
Adriano Grigolo, Thiago F. Viscondi, Marcus A. M. de Aguiar
A generalized version of the coupled coherent states method for coherent states of arbitrary Lie groups is developed. In contrast to the original formulation, which is restricted t…
Semiclassical Propagator in the Generalized Coherent-State Representation
Thiago F. Viscondi, Adriano Grigolo, Marcus A. M. de Aguiar
A detailed derivation of the semiclassical propagator in the generalized coherent-state representation is performed by applying the saddle-point method to a path integral over the…
Topological structures in the Husimi flow
Matheus Veronez, Marcus A. M. de Aguiar
We study the topological properties of the quantum phase space current in the Husimi representation, focusing on the dynamical differences, induced by these properties, between the…
Phase space flow in the Husimi representation
M. Veronez, M. A. M. de Aguiar
We derive a continuity equation for the Husimi function evolving under a general non-hermitian Hamiltonian and identify the phase space flow associated with it. For the case of uni…
Evaluation of the semiclassical coherent state propagator in the presence of phase space caustics
A D Ribeiro, M A M de Aguiar
A uniform approximation for the coherent state propagator, valid in the vicinity of phase space caustics, was recently obtained using the Maslov method combined with a dual represe…
Semiclassical Husimi functions for spin systems
Marcel Novaes, Marcus A. M. de Aguiar
We derive a semiclassical approximation to the Husimi functions of stationary states of spin systems. We rederive the Bohr-Sommerfeld quantization for spin by locating the poles of…
Semiclassical Approximations in Phase Space with Coherent States
M. Baranger, M. A. M. de Aguiar, F. Keck +2
We present a complete derivation of the semiclassical limit of the coherent state propagator in one dimension, starting from path integrals in phase space. We show that the arbitra…
