An introduction to the de Broglie-Bohm pilot-wave theory

Samuel Colin, de l’Université de Cergy-Pontoise, professeur invité dans le cadre du Master Erasmus+ Europhotonics donnera un séminaire intiutlé :"An introduction to the de Broglie-Bohm pilot-wave theory" le mercredi 29 mai 2019 à 15h00 en salle Pierre Cotton du laboratoire.

Résumé :
The pilot-wave theory is an alternative quantum theory which was first proposed by Louis de Broglie in 1927.
Contrary to the Copenhagen interpretation, which became the standard interpretation of quantum mechanics, the pilot-wave theory is deterministic and it presupposes that quantum systems are not only described by wave functions but also by actual configurations.
For example, a non-relativistic quantum particle is not only described by its wave-function but also by its position, which is guided by the wave-function in a deterministic way (hence the name pilot-wave).
Many quantum paradoxes can be avoided in the pilot-wave theory.
Moreover the theory can be applied where the standard theory cannot, for example in the field of quantum cosmology.
It also helps to interpret trajectories of single photons observed by Steinberg in Toronto.
This seminar will be an introduction to the pilot-wave theory : I will illustrate it with a few movie animations,
I will show how the Born law emerges from the two equations of motion that define the pilot-wave theory and I will discuss its new physics.
