Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Description
Mathematical methods play a significant role in the rapidly growing field of nonlinear optical materials. This volume discusses a number of successful or promising contributions. The overall theme of this volume is twofold: (1) the challenges faced in computing and optimizing nonlinear optical material properties; and (2) the exploitation of these properties in important areas of application. These include the design of optical amplifiers and lasers, as well as novel optical switches. Research topics in this volume include how to exploit the magnetooptic effect, how to work with the nonlinear optical response of materials, how to predict laser-induced breakdown in efficient optical devices, and how to handle electron cloud distortion in femtosecond processes.

Book Description
Les transferts thermiques sont une science clé de l’énergie. Cet ouvrage aborde les principaux modes de transferts d’énergie : la conduction, le rayonnement et la convection. Ces phénomènes très différents, mais pouvant interagir, doivent être connus de l’étudiant qui sera confronté un jour ou l’autre à un problème de transfert thermique. Il trouvera dans ce cours de nombreuses applications concrètes (centrales nucléaires, panneaux solaires, propulseur Vulcain...) ainsi que de nombreux exercices corrigés. Dans cette sixième édition entièrement actualisée, la priorité est donnée à la compréhension physique des phénomènes et à l’apprentissage de la modélisation physique. Le chapitre sur le rayonnement des milieux semi-transparents a été entièrement refondu pour intégrer des avancées récentes des concepts et des méthodes.

Book Description
Ce manuel aborde la résolution des problèmes d’énergétique et de transferts thermiques à l’échelle macroscopique. Après un rappel de thermodynamique, l’ouvrage décrit la modélisation des transferts de chaleur. Les transferts par conduction, convection et rayonnement sont expliqués en détail. Chaque cas expose l’origine physique des transferts puis les outils de modélisation permettant de traiter les problèmes rencontrés en pratique. Cette nouvelle édition est complétée de nouveaux exemples illustrant les concepts de thermodynamique propres à l’énergétique. La conduction en régime transitoire est également abordée. Chaque chapitre propose un exposé pédagogique des connaissances de base en thermique, accompagné d’exercices corrigés.
