20.500.12556/DKUM-93522 Quantum-classical correspondence between quantum chaos and finite-time classical dynamics Although the importance of quantum-classical correspondence has been recognized in numerous studies of quantum chaos, its usefulness in understanding quantum chaos through finite-time classical dynamics remains less well understood.We address this question in this work by performing a detailed analysis of how the quantum chaotic measure relates to the chaoticity of the finite-time classical trajectories. A good correspondence between them has been revealed in time- dependent and many-body systems, both of them being of the mixed type. In particular, we show that the dependence of the quantum chaotic measure on the chaoticity of finite-time trajectories can be well captured by a function that is independent of the system. This strongly implies the universal validity of the finite-time quantum-classical correspondence. Our findings enhance the understanding of quantum-classical correspondence and provide a promising approach to explore the ergodic hierarchy in quantum systems. quantum chaos finite-time classical dynamics quantum-classical correspondence dynamical chaos mixed type kicked top model Dicke model kvantni kaos klasična dinamika v končnem času kvantno-klasična korespondenca dinamični kaos mešani tip true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2025-07-01 03:09:35 2025-11-03 15:05:32 2025-11-06 09:55:06 0000-00-00 00:00:00 2025 0 0 Str. 1-10 št. 5, št. članka 054211 Letn. 111 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-09-10 2025-04-21 2025-05-16 530.145 236584451 10.1103/PhysRevE.111.054211 2470-0045 Wang_2025_Quantum-classical_correspondence_.pdf Wang_2025_Quantum-classical_correspondence_.pdf 1 CE8AA61F55E230EE0100B310D5AD253A 23953dc0795bb01eff94d355594aba2057efc863a1093b71cd7a4133efa0a789 e69e9f78-b8bd-11f0-b13b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200361 https://doi.org/10.1103/PhysRevE.111.054211 0 095879fb-b8be-11f0-b13b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200362 Univerza v Mariboru 0 0 0
