- Abstract summary: We develop a generic theoretical mechanism responsible for the generation of chaos in an arbitrary Bohmian system.
We study the effect of chaos on Bohmian trajectories and study chaos and ergodicity in qubit systems.
Our results shed light on a fundamental problem in Bohmian Mechanics, namely whether there is a dynamical approximation of Born's rule by an arbitrary initial distribution of Bohmian particles.

- Abstract: This is a short review in the theory of chaos in Bohmian Quantum Mechanics
based on our series of works in this field. Our first result is the development
of a generic theoretical mechanism responsible for the generation of chaos in
an arbitrary Bohmian system (in 2 and 3 dimensions). This mechanism allows us
to explore the effect of chaos on Bohmian trajectories and study in detail
(both analytically and numerically) the different kinds of Bohmian trajectories
where, in general, chaos and order coexist. Finally we explore the effect of
quantum entanglement on the evolution of the Bohmian trajectories and study
chaos and ergodicity in qubit systems which are of great theoretical and
practical interest. We find that the chaotic trajectories are also ergodic,
i.e. they give the same final distribution of their points after a long time
regardless of their initial conditions. In the case of strong entanglement most
trajectories are chaotic and ergodic and an arbitrary initial distribution of
particles will tends to Born's rule over the course of time. On the other hand,
in the case of weak entanglement the distribution of Born's rule is dominated
by ordered trajectories and consequently an arbitrary initial configuration of
particles will not tend, in general, to Born's rule, unless it is initially
satisfied. Our results shed light on a fundamental problem in Bohmian
Mechanics, namely whether there is a dynamical approximation of Born's rule by
an arbitrary initial distribution of Bohmian particles.

We extend the old attempt made by Louis de broglie for interpreting quantum mechanics in realistic terms, namely the double solution.
We are able to justify wave-particle duality and to explain the violations of Bell's inequalities.

Quantum chaos, a phenomenon that began to be studied in the last century, still does not have a rigorous understanding.
We propose the quantum chaos definition in the manner similar to the classical one using decoherent histories as a quantum analogue of trajectories.
We show that for such a model, the production of entropy of decoherent histories is radically different in integrable and chaotic regimes.

We study in detail the onset of chaos and the probability measures formed by individual Bohmian trajectories in entangled states of two-qubit systems.
In weakly entangled states chaos is manifested through the sudden jumps of the Bohmian trajectories between successive Lissajous-like figures.
In strongly entangled states, the chaotic form of the Bohmian trajectories is manifested after a short time.

A trajectory is not an outcome of a quantum measurement, in the sense that there is no observable associated with it.
