  Bohmian mechanics is an interpretation of quantum mechanics that describes
the motion of quantum particles with an ensemble of deterministic trajectories.
Several attempts have been made to utilize Bohmian trajectories as a
computational tool to simulate quantum systems consisting of many particles, a
very demanding computational task. In this paper, we present a novel ab-initio
approach to solve the many-body problem for bosonic systems by evolving a
system of one-particle wavefunctions representing pilot waves that guide the
Bohmian trajectories of the quantum particles. In this approach, quantum
entanglement effects arise due to the interactions between different
configurations of Bohmian particles evolving simultaneously. The method is used
to study the breathing dynamics and ground state properties in a system of
interacting bosons.
