Following Oriols (2007 Phys. Rev. Lett. 98 066803), an algorithm to deal with the exchange interaction in non-separable quantum systems is presented. The algorithm can be applied to fermions or bosons and, by construction, it exactly ensures that any observable is totally independent of the interchange of particles. It is based on the use of conditional Bohmian wave functions which are solutions of single-particle pseudo-Schrödinger equations. The exchange symmetry is directly defined by… 
Stochastic Schrödinger Equations and Conditional States: A General Non-Markovian Quantum Electron Transport Simulator for THz Electronics
A time-dependent quantum Monte Carlo algorithm is presented to describe electron transport in open quantum systems under general (Markovian or non- Markovian) conditions and makes the most of trajectory-based and wavefunction methods.
Dissipative quantum transport using one-particle time-dependent (conditional) wave functions
An effective single-particle Schrodinger equation to include dissipation into quantum devices is presented. This effective equation is fully understood in the context of Bohmian mechanics, a theory
Quantum noise from a Bohmian perspective: fundamental understanding and practical computation in electron devices
This work explains quantum noise associated to an electron impinging upon a semitransparent barrier using Bohmian mechanics (which deals with wave functions and point-like particles), and Numerical simulations of low and high frequency features of quantum shot noise in a resonant tunneling diode are presented, showing the usefulness of this approach.

Abstract Bohmian mechanics provides an explanation of quantum phenomena in terms of point-like particles guided by wave functions. This review focuses on the use of nonrelativistic Bohmian mechanics

We discuss the conditions for the classicality of quantum states with a very large number of identical particles. By treating the center of mass as a Bohmian particle, we show that it follows a

Time-dependent exchange and tunneling: detection at the same place of two electrons emitted simultaneously from different sources.
Two-particle scattering probabilities in tunneling scenarios with exchange interaction are analyzed with quasi-particles wave packets and the far-reaching consequences of these non-zero probabilities in the accurate evaluation of quantum noise in mesoscopic systems are briefly indicated.
Can the wave function in configuration space be replaced by single-particle wave functions in physical space?
This work introduces an alternative approach which aims at achieving empirical adequacy with a more modest ontological complexity, and provides some preliminary evidence for optimism regarding the (once popular but prematurely-abandoned) program of trying to replace the configuration space wave function with a (totally unproblematic) set of fields in ordinary physical space.
Origin of chaos near three-dimensional quantum vortices: A general Bohmian theory.
It is shown that nearby invariant lines of the comoving quantum flow, called X lines, which are normally hyperbolic, produce chaotic scatterings of nearby quantum (Bohmian) trajectories, thus inducing an intricate form of the quantum current in the neighborhood of each 3D quantum vortex.

The direct solution of the many-particle Schrodinger equation is computationally inaccessible for more than very few electrons. In order to surpass this limitation, one of the authors [X. Oriols,
