Quantum Phase Transitions Through Quantum Information Window by Aditi De
Explore quantum phase transitions through the lens of quantum information in this 51-minute colloquium talk. Delve into the role of bipartite and multipartite entanglement as detectors of quantum phase transitions in many-body systems. Examine recent investigations on dynamical quantum phase transitions and how entanglement can detect these phenomena. Learn about the theory of entanglement, two-party paradigms, and mixed states. Discover experimental achievements in ultracold atoms and superconducting qubits. Investigate quantum spin models, including ATXY and DATXY models, and their quantum phases. Understand the concept of dynamical quantum phase transitions and methods to detect them. Analyze results showing entanglement measures as powerful as rate functions in detecting these transitions. Gain insights into the potential of quantum spin models for realizing information processing tasks and their experimental implementations.
