Topological Entanglement-Spectrum Crossing in Quench Dynamics
Zongping Gong, Masahito Ueda
We unveil the stable -dimensional topological structures underlying the quench dynamics for all the Altland-Zirnbauer classes in dimension, and propose to detect such…
Verification of the Quantum Nonequilibrium Work Relation in the Presence of Decoherence
Andrew Smith, Yao Lu, Shuoming An +6
Although nonequilibrium work and fluctuation relations have been studied in detail within classical statistical physics, extending these results to open quantum systems has proven…
Discrete Time-Crystalline Order in Cavity and Circuit QED Systems
Zongping Gong, Ryusuke Hamazaki, Masahito Ueda
Discrete time crystals are a recently proposed and experimentally observed out-of-equilibrium dynamical phase of Floquet systems, where the stroboscopic evolution of a local observ…
Fluctuation theorems in feedback-controlled open quantum systems: quantum coherence and absolute irreversibility
Yûto Murashita, Zongping Gong, Yuto Ashida +1
Thermodynamics of quantum coherence has attracted growing attention recently, where the thermodynamic advantage of quantum superposition is characterized in terms of quantum thermo…
