Are quantum trajectories suitable for semiclassical approximations?
Alfredo M. Ozorio de Almeida
The quantum trajectories in the de Broglie-Bohm formulation of quantum mechanics depend on an additional quantum potential derived from the full wave solution of Schrödinger's equa…
Energy transition density of driven chaotic systems: A compound trace formula
Alfredo M. Ozorio de Almeida
Oscillations in the probability density of quantum transitions of the eigenstates of a chaotic Hamiltonian within classically narrow energy ranges have been shown to depend on clos…
Quantum revival patterns from classical phase-space trajectories
Gabriel M. Lando, Raúl O. Vallejos, Gert-Ludwig Ingold +1
A general semiclassical method in phase space based on the final value representation of the Wigner function is considered that bypasses caustics and the need to root-search for cl…
Markovian evolution of Gaussian states in the semiclassical limit
O. Brodier, A. M. Ozorio de Almeida
We derive an approximate Gaussian solution of the Lindblad equation in the semiclassical limit, given a general Hamiltonian and linear coupling with the environment. The theory is…
Quantum baker maps with controlled-NOT coupling
Raul O. Vallejos, P. R. del Santoro, A. M. Ozorio de Almeida
The characteristic stretching and squeezing of chaotic motion is linearized within the finite number of phase space domains which subdivide a classical baker map. Tensor products o…
On the semiclassical evolution of quantum operators
A. M. Ozorio de Almeida, O. Brodier
The Heisenberg evolution of a given unitary operator corresponds classically to a fixed canonical transformation that is viewed through a moving coordinate system. The operators th…
