Hi all,
Tomorrow we have just one student talk, from Romain Moyard, who will tell us about his semester project entitled "Path integral formalism and quantum foundations". The abstract is below.
Best,

Abstract:
During the 60s R. Feynman developed the path integral formalism, a version of quantum mechanics involving Lagrangians. The probabilities obtained within this formalism are the same as in the canonical one, their prediction power is equivalent. Since that time, path integral formalism has been widely used to compute probabilities and extended research was done to develop mathematical tools to facilitate the computation. However, there have been few attempts to use this framework in quantum foundations. In this talk I will present how it is possible to describe a spin-measurement process using path integrals. I will also elaborate on what dichotomy exists between canonical quantum mechanics and path integral formalism when it comes to questions about quantum foundations like the measurement problem and the lack of realism.
