Matière et lumière sont intimement liées dans notre modélisation du monde physique. De l’élaboration de la théorie quantique à l’invention du laser, l’interaction entre atomes et rayonnement a joué un rôle central dans le développement de la science et de la technologie d’aujourd’hui. La maîtrise de cette interaction permet désormais d’atteindre les plus basses températures jamais mesurées. Le refroidissement de gaz d’atomes par la lumière d’un laser conduit à une « matière quantique » aux propriétés radicalement différentes des fluides ordinaires. Ces atomes froids sont à la base d’une nouvelle métrologie du temps et de l’espace, qui trouve des applications dans des domaines aussi divers que la navigation, les télécommunications ou encore la géophysique.

Light and matter are very closely linked in our modelling of the physical world. From the formulation of quantum theory to the invention of laser, the interaction between atoms and radiation has played a crucial role in the development of today’s science and technology. By controlling this interaction, the lowest temperatures ever recorded are now reached. Cooling atomic gases with laser light produces “quantum matter” with radically different properties from those of ordinary fluids. These cold atoms are the cornerstone of a new metrology of time and space, with applications in a wide variety of fields, including navigation, telecommunication and geophysics.

The Standard Model of elementary particles and interactions is one of the best tested theories in physics. It has been found to be in remarkable agreement with experiment, and its validity at the quantum level has been successfully probed in the electroweak sector. In spite of its experimental successes, though, the Standard Model suffers from a number of limitations, and is likely to be an incomplete theory. It contains many arbitrary parameters; it does not include gravity, the fourth elementary interaction; it does not provide an explanation for the hierarchy between the scale of electrowea

It has been recognised recently that the strange features of the quantum world could be used for new information transmission or processing functions such as quantum cryptography or, more ambitiously, quantum computing. These fascinating perspectives renewed the interest in fundamental quantum properties and lead to important theoretical advances, such as quantum algorithms and quantum error correction codes. On the experimental side, remarkable advances have been achieved in quantum optics, solid state physics or nuclear magnetic resonance. This book presents the lecture notes of the Les Houc

There has been recently some interdisciplinary convergence on a number of precise topics which can be considered as prototypes of complex systems. This convergence is best appreciated at the level of the techniques needed to deal with these systems, which include: 1) A domain of research around a multiple point where statistical physics, information theory, algorithmic computer science, and more theoretical (probabilistic) computer science meet: this covers some aspects of error correcting codes, stochastic optimization algorithms, typical case complexity and phase transitions, constr
