Entanglement Entropies in One-Dimensional Systems Luca Taddia

Quantum phase transition are phase transitions occurring at zero absolute temperature: classical fluctuations are completely suppressed, and quantum effects become macroscopic. Their detection and the exploration of their properties are among the main objectives of quantum many-body theory. In this book, we explore how quantum-information concepts, namely entaglement entropies, can help in such a mission, and provide quantitative information about the physics of closed one-dimensional lattice systems.
