Finite-Size Scaling of the Full Eigenstate Thermalization in Quantum Spin Chains
Yuke Zhang, Pengfei Zhang
Despite the unitary evolution of closed quantum systems, long-time expectation of local observables are well described by thermal ensembles, providing the foundation of quantum sta…
Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor
Jia-Nan Yang, Lata Kh Joshi, Filiberto Ares +3
Quantum many-body systems display an extraordinary degree of complexity, yet many of their features are universal: they depend not on microscopic details, but on a few fundamental…
Distinguishing Coherent and Incoherent Errors in Multi-Round Time-Reversed Dynamics via Scramblons
Zeyu Liu, Pengfei Zhang
Despite the rapid development of quantum science and technology, errors are inevitable and play a crucial role in quantum simulation and quantum computation. In quantum chaotic sys…
Emergent Universality Class in Dissipative Quantum Systems with Dipole Moment Conservation
Wenbo Zhou, Yuke Zhang, Pengfei Zhang
Understanding the non-equilibrium dynamics of quantum many-body systems remains one of the grand challenges of modern physics. In particular, increasing attention has been devoted…
Twist Coefficients of Periodic Orbits of Minkowski Billiards
Carlos Villanueva, Pengfei Zhang
We investigate the fundamental properties of Minkowski billiards and introduce a new coordinate system on the phase space . In this coordinate system, the Mink…
