Quantum Many-Body Physics in Open Systems: Measurement and Strong Correlations

Detailed Summary of the Book

The book begins with a comprehensive introduction to quantum many-body physics and the essential mathematical tools required to study open systems. Readers are introduced to key concepts such as non-equilibrium quantum dynamics, environments' role in quantum coherence, and the emergence of novel physical phenomena due to dissipation. By dissecting the mechanics behind real-world quantum measurements, Yuto Ashida provides readers with a holistic view of how measurement-backaction fundamentally influences the evolution of quantum states.

A significant portion of the text addresses the critical concept of strong correlations—interactions between particles that cannot be treated as small perturbations. These correlations give rise to diverse phenomena such as quantum magnetism, Mott transitions, and fractional excitations. Through eloquent explanations and illustrative examples, the book frames these ideas in the context of open-system environments, where thermal baths, driving forces, and measurement processes play pivotal roles.

The latter chapters refine these ideas by delving into cutting-edge topics, including quantum thermalization, entanglement growth, and the emergence of steady states under driven-dissipative conditions. Ashida also brings an exciting focus to novel applications in quantum information science, quantum computing, and the development of synthetic quantum materials.
