The eighth and ninth lessons were devoted to Schrödinger cats produced in cavity quantum electrodynamics experiments. An atom interacts with the field stored in a high-surge cavity, and its strongly non-linear coupling with the field produces photonic …

The seventh lesson was devoted to the study of nonlinearities in Bose Einstein condensates, due to interactions between atoms. These interactions, linked to elastic collisions in the sample, have the effect of introducing a non-linear term into the …

The sixth lesson dealt with the study of matter waves (atomic optics). For some years now, we've been able to produce ultra-cold samples of atoms forming Bose Einstein condensates, in which a large number of atoms are all in the same wave function, with …

The fifth lesson described field states in phase space, introducing two important functions defined in this space, Wigner's Q-function and W-function. These functions provide a pictorial and intuitive description of Fock states, coherent states and their …

Effective blood pressure control, especially of the systolic component, is of primary importance in both primary and secondary prevention of Cardiovascular and Cerebrovascular Events. Similarly, systolic blood pressure control is important in the primary …

A Collège de France - CNED coproduction Abstract By associating a method - comparative studies - with a process in progress - the internationalization of law -, this Chair looks to the future, however uncertain that future may be. Admittedly, current …

The fourth lesson addressed the problem of non-linear splitters in quantum optics. After noting that the photon distribution achieved in the final channels of a linear splitter did not in any case allow the realization of a mesoscopic superposition of the …
