Book Description
The Earth is the only planet in the Solar System where liquid water is present on the surface, a condition that seems necessary for the development of life. Its sisters Venus and Mars are extremely different. Why did these three planets, born under fairly comparable conditions, evolve to the conditions we observe today? Understanding the physical or chemical factors that are at the origin of such divergent evolutions is a first step in an approach to the problem of the origin of life on Earth.

Book Description
Les physiciens savent produire des gaz à quelques milliardièmes de degrés au-dessus du zéro absolu. Les méthodes de refroidissement s’appliquent non seulement aux atomes mais aussi aux ions et aux molécules. Ce domaine de recherche a été couronné deux fois par le prix Nobel. Il s’est extraordinairement enrichi depuis que l’on sait faire varier à volonté les interactions entre les particules et piéger celles-ci avec des pinces optiques ou dans des réseaux optiques à la géométrie ajustable. On édifie ainsi des cristaux artificiels formés d’atomes ou de molécules qui peuvent simuler la structure de la matière et élucider certaines de ses propriétés magnétiques, avec la perspective d’expliquer un jour la supraconductivité à haute température. Le phénomène d’intrication quantique est à la base de nouveaux dispositifs pour le stockage et la transmission de l’information quantique. Des progrès spectaculaires sont constamment enregistrés en métrologie. Ainsi des horloges à atomes ou à ions ultrafroids mesurent le temps à mieux qu’une seconde sur la durée de l’Univers. Des gravimètres et gyromètres industriels d’un type nouveau améliorent la sensibilité de la sismologie et la navigation dans l’espace. En outre, l’extrême précision des mesures permet de tester les lois fondamentales de la physique, par exemple l’électrodynamique quantique, l’invariance de Lorentz ou les éventuelles variations des constantes fondamentales. Le domaine des particules ultrafroides rejoint aujourd’hui ceux de la matière condensée, de la chimie et même de la cosmologie.

Book Description
The first part provides a general introduction to the electronic structure of quasi-two-dimensional systems with a particular focus on group-theoretical methods. The main part of the monograph is devoted to spin-orbit coupling phenomena at zero and nonzero magnetic fields. Throughout the book, the main focus is on a thorough discussion of the physical ideas and a detailed interpretation of the results. Accurate numerical calculations are complemented by simple and transparent analytical models that capture the important physics.

Book Description
The physics of strong light-matter coupling has been addressed in different scientific communities over the last three decades. Since the early eighties, atoms coupled to optical and microwave cavities have led to pioneering demonstrations of cavity quantum electrodynamics, Gedanken experiments, and building blocks for quantum information processing, for which the Nobel Prize in Physics was awarded in 2012. In the framework of semiconducting devices, strong coupling has allowed investigations into the physics of Bose gases in solid-state environments, and the latter holds promise for exploiting light-matter interaction at the single-photon level in scalable architectures. More recently, impressive developments in the so-called superconducting circuit QED have opened another fundamental playground to revisit cavity quantum electrodynamics for practical and fundamental purposes. This book aims at developing the necessary interface between these communities, by providing future researchers with a robust conceptual, theoretical and experimental basis on strong light-matter coupling, both in the classical and in the quantum regimes. In addition, the emphasis is on new forefront research topics currently developed around the physics of strong light-matter interaction in the atomic and solid-state scenarios.

Book Description
The feasibility of using indium seals for large vacuum bell jars has been investigated. It is shown that such seals can be made; however, use of this type seal for repetitive operations is not recommended.
