Chaotic Bohmian trajectories for stationary states

Abstract: In Bohmian mechanics, the nodes of the wave function play an important role in the generation of chaos. However, so far, most of the attention has been on moving nodes; little is known about the possibility of chaos in the case of stationary nodes. We address this question by considering stationary states, which provide the simplest examples of wave functions with stationary nodes. We provide examples of stationary wave functions for which there is chaos, as demonstrated by numerical computations, for one part… Show more

“…The mechanism of generation of chaos is thought to be well understood in 2-d quantum systems [1,2,13,14,15,16,17,18,19,20,21]. However, only few works exist in the 3-d or higher dimensional cases, due to the far higher complexity of the problem [16,22,23,24].…”

“…Having as a goal the exploration of chaos in the presence of QE (see also [23,24,25]), in a previous paper [26] we gave the basic characteristics of the Bohmian trajectories in an entangled two-qubit system, where the basic qubit states in one dimension are realized as properly engineered coherent states of the unperturbed quantum harmonic oscillator. We chose to work with this system, since it is quite well understood from a quantum mechanical standpoint and is easily constructed and controlled in the laboratory.…”

“…On the other hand, the existence of trajectories in BQM allows us to define and study quantum chaotic behaviour by applying all the techniques of classical dynamical systems. Thus chaos in Bohmian Dynamics has attracted a lot of interest in the last decades [20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39].…”
