Stochastic Bohmian and Scaled Trajectories

Abstract: In this review we deal with open (dissipative and stochastic) quantum systems within the Bohmian mechanics framework which has the advantage to provide a clear picture of quantum phenomena in terms of trajectories, originally in configuration space. The gradual decoherence process is studied from linear and nonlinear Schrödinger equations through Bohmian trajectories as well as by using the so-called quantumclassical transition differential equation through scaled trajectories. This transition is governed by a… Show more

“…At this level, it is interesting to point out that this process studied within this theoretical scheme displays decoherence due to the gradual transition from the quantum to the classical regime. This kind of studies has been extended to dissipative and stochastic dynamics in the framework of the CK and the so-called Schrödinger-Langevin or Kostin equations, respectively [28,29,31].…”

“…Chou applied this wave equation to analyze wave-packet interference [16] and the dynamics of the harmonic and Morse oscillators with complex trajectories [17]. Stochastic Bohmian and scaled trajectories have also been discussed in the literature for open quantum systems [18]. Moreover, if a time-dependent Gaussian ansatz is assumed for the probability density, Bohmian and scaled trajectories are expressed as a sum of a classical trajectory (that is, a particle feature) and a term containing the width of the corresponding wave packet (that is, a wave feature), which has been called the dressing scheme [12].…”
