Sommario/riassunto |

La reconnaissance internationale de la littérature latino-américaine au xxe siècle a souvent été interprétée par la critique comme le résultat de l'influence du modernisme, notamment du fait de la lecture, par les auteurs latino-américains, de James Joyce et de William Faulkner. Certains auteurs du continent, pourtant, suivent des stratégies différentes : Jorge Luis Borges, Adolfo Bioy Casares et Julio Cortázar utilisent les fondements de la littérature de genre (fantastique, policier, horreur, roman d'aventure) pour opérer une reconfiguration des équilibres entre le champ littéraire et les injonctions politiques, nationales et culturelles. Dans cette optique, le travail de Robert Louis Stevenson sur les publics populaires et le croisement des genres peut être vu comme une référence idéale, du fait de sa complexité et de son souci constant d'expérimentation. Cette étude a donc pour objectif de proposer une comparaison de ces stratégies, en utilisant les outils conceptuels et théoriques de la littérature mondiale. Stevenson, de cette manière, pourra apparaître comme un modèle herméneutique pour penser et résoudre certains dilemmes géographiques et littéraires. |

Sommario/riassunto |
|
An accessible introduction to advanced quantum theory, this graduate-level textbook focuses on its practical applications rather than mathematical technicalities. It treats real-life examples, from topics ranging from quantum transport to nanotechnology, to equip students with a toolbox of theoretical techniques. Beginning with second quantization, the authors illustrate its use with different condensed matter physics examples. They then explain how to quantize classical fields, with a focus on the electromagnetic field, taking students from Maxwell's equations to photons, coherent states and absorption and emission of photons. Following this is a unique master-level presentation on dissipative quantum mechanics, before the textbook concludes with a short introduction to relativistic quantum mechanics, covering the Dirac equation and a relativistic second quantization formalism. The textbook includes 70 end-of-chapter problems. Solutions to some problems are given at the end of the chapter and full solutions to all problems are available for instructors at www.cambridge.org/9780521761505. |
