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…
Initial value representation for the SU(n) semiclassical propagator
Thiago F. Viscondi, Marcus A. M. de Aguiar
The semiclassical propagator in the representation of SU(n) coherent states is characterized by isolated classical trajectories subjected to boundary conditions in a doubled phase…
Dynamics of a Bose-Einstein condensate in a symmetric triple-well trap
T. F. Viscondi, K. Furuya
We present a complete analysis of the dynamics of a Bose-Einstein condensate trapped in a symmetric triple-well potential. Our classical analogue treatment, based on a time-depende…
Phase Transition, Entanglement and Squeezing in a Triple-Well Condensate
T. F. Viscondi, K. Furuya, M. C. de Oliveira
We provide an in-depth characterization of a three modes Bose-Einstein condensate trapped in a symmetric circular triple well potential. We analyze how a subsystem independent meas…
Generalized Purity and Quantum Phase Transition for Bose-Einstein condensates in a Symmetric Double Well
Thiago F. Viscondi, K. Furuya, M. C. de Oliveira
The generalized purity is employed for investigating the process of coherence loss and delocalization of the Q-function in the Bloch sphere of a two-mode Bose-Einstein condensate i…
