Sub-Compton Quantum Non-equilibrium and Majorana Systems
Speaker(s): Samuel Colin
Abstract: In the de Broglie-Bohm pilot-wave theory, an ensemble of fermions is not only described by a spinor,  but also by a distribution of position beables. If the distribution of positions is different from the one predicted by the Born rule, the ensemble is said to be in quantum non-equilibrium.... read more

The zig-zag road to reality
Speaker(s): Samuel Colin
Abstract: The de Broglie-Bohm pilot-wave program is an attempt to formulate quantum theory (including quantum field theory) as a theory without observers, by assuming that the wave-function is not the complete description of a system, but must be supplemented by additional variables (beables). Although many p... read more

Dynamical origin of quantum probabilities revisited
Speaker(s): Samuel Colin
Abstract: The de Broglie-Bohm theory is about non-relativistic point-particles that move deterministically along trajectories. The theory reproduces the predictions of standard quantum theory given that the distribution of particle positions over an ensemble of systems, all described by the same wavefunction ... read more

Nonrelativistic limit of quantum field theory
Speaker(s): Samuel Colin
Abstract: It is usually expected that nonrelativistic many-body Schroedinger equations emerge from some QFT models in the limit of infinite masses. For instance, from Yukawa's QFT, if the initial state contains 2 fermions, we expect to recover a 2-fermion nonrelativistic Schroedinger equation with 2-body Yuka... read more

Bohm-Bell beables for quantum field theory
Speaker(s): Samuel Colin
Abstract: The problem of associating beables (hidden variables) to QFT, in the spirit of what Bohm did for nonrelativistic QM, is not trivial. In 1984, John Bell suggested a way of solving the problem, according to which the beables are the positions of fermions, in a discretized version of QFT, and obey a st... read more
