- Abstract: I argue that Bohmian mechanics (or any similar pilot-wave theory) cannot
reasonably be claimed to be a deterministic theory. If one assumes the "quantum
equilibrium distribution" provided by the wave function of the universe,
Bohmian mechanics requires an external random oracle in order to describe the
(Kolmogorov-Levin-Chaitin) algorithmic randomness properties of typical outcome
sequences of long runs of repeated identical experiments (which provably follow
from the Born rule). This oracle lies beyond the scope of Bohmian mechanics (or
any deterministic extension thereof), including the impossibility of explaining
the randomness property in question from "random" initial conditions. Thus the
advantages of Bohmian mechanics over other interpretations of quantum
mechanics, if any, must lie at an ontological level, and in its potential to
derive the quantum equilibrium distribution and hence the Born rule.

We will show that QT for both distinguishable and indistinguishable particles can be formulated in this way.

We show that collapse models and their primitive ontology can be recast as Bohmian theories.
This reformulation of collapse models as Bohmian theories brings to fore the question of whether there exists unromantic' realist interpretations of quantum theory.

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.

Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality.
This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment.
It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.

We show how to overcome this problem by considering a special case of our generic inequality that can be experimentally tested point-by-point in time.
