Many-body scars in quantum Heisenberg XY models and analog simulations on superconducting circuits

Abstract: Quantum many-body systems lie at the heart of modern fundamental physics. The study of these systems has revealed a plethora of fascinating phenomena, such as quantum thermalization, many-body localization, and quantum many-body scars. This review provides a comprehensive overview of the recent advances in understanding quantum many-body scars and non-ergodic dynamics in quantum systems on superconducting-circuit platforms, ranging from theoretical mechanisms and effective models to experimental observations.

Key words: Quantum many-body scars; Quantum chaos; Quantum simulation; Superconducting circuits
