[Quantic mechanics and microscopic observation].

This paper investigates the physical, experimentable, reality of multiple worlds of Quantum Mechanics. On the basis of a reflection on the fundamental principles of physics (sec. I.A), firmly rejecting the incomprehension imperative often associated with Quantum Mechanics (sec. I.B), and strongly relying on an experimental methodology (sec. I.B) and on the superposition principle, we propose a unified interpretation of quantum physics (sec. II), the potential world modal interpretation. This framework makes multiple-world and pilot-wave interpretations converge. It also clarifies the concepts of potential world and sub-quantical potential particle. Then, we turn to Relativity and sketch out an emergence of Special Relativity without "rods and clocks" (sec. III.A) providing a cinematic and phenomenal interpretation of SR. We suggest to distinguish between given and received gravitation and reason on it at a sub-quantical level (sec. III.B) and formulate the hypothesis that weight is active between potential worlds (sec. III.C). If this effect follows the von Neumann chain, it should be observable with available techniques (sec. III.D). If correct, this hypothesis could contribute explanations for cosmic inflation, dark matter and the cosmological constant problem (sec. IV). Moreover, our cinematic interpretation of relativity in an expanding universe might lead to a justification of the MOND theory (sec. IV.B.3).

Some temporal Bell inequalities are deduced under the assumption of realism and perfect correlation. No locality condition is needed. When the system is macroscopic, the perfect correlation assumption substitutes the noninvasive measurability hypothesis advanteousgely. The new inequalities are violated quantically. This violation is clearly more severe than the similar violation in the case of ordinary Bell inequalities. Some microscopic and macroscopic situations in which these inequalities could be tested are considered.

Dipolar quantum gases have gathered a lot of experimental and theoretical interest in the last years. The combination of long-ranged interaction and anisotropy enriches the phase diagram of the system and leads to new and exotic phases. In real experiments the system is usually confined by means of magnetic traps. In this project the student will perform a microscopic analysis of a system of dipolar bosons moving on the plane while being spatially confined by means of an external field.
