Entanglement dynamics for two interacting spins
Marcel Novaes
We study the dynamical generation of entanglement for a very simple system: a pair of interacting spins, s1 and s2, in a constant magnetic field. Two different situations are consi…
Real trajectories in the semiclassical coherent state propagator
Marcel Novaes
The semiclassical approximation to the coherent state propagator requires complex classical trajectories in order to satisfy the associated boundary conditions, but finding these t…
A Uniform Approximation for the Coherent State Propagator using a Conjugate Application of the Bargmann Representation
A. D. Ribeiro, M. Novaes, M. A. M. de Aguiar
We propose a conjugate application of the Bargmann representation of quantum mechanics. Applying the Maslov method to the semiclassical connection formula between the two represent…
Semiclassical propagation of spin coherent states
M. Novaes
The semiclassical propagation of spin coherent states is considered in complex phase space. For two time-independent systems we find the appropriate classical trajectories and show…
Semiclassical propagation of coherent states using complex and real trajectories
M. Novaes, M. A. M. de Aguiar
We study the semiclassical propagation of coherent states in dimensions, which in general involves complex classical dynamics. Several simple approximations are derived that de…
