20.500.12556/RUL-164945 Momentum-dependent quantum Ruelle-Pollicott resonances in translationally invariant many-body systems We study Ruelle-Pollicott resonances in translationally invariant quantum many-body lattice systems via spectra of a momentum-resolved operator propagator on infinite systems. Momentum dependence gives insight into the decay of correlation functions, showing that, depending on their symmetries, different correlation functions in general decay with different rates. Focusing on the kicked Ising model, the spectrum seems to be typically composed of an annular random matrix-like ring whose size we theoretically predict, and few isolated resonances. We identify several interesting regimes, including a mixing regime with a power-law decay of correlation functions. In that regime, we also observe a huge difference in timescales of different correlation functions due to an almost conserved operator. An exact expression for the singular values of the operator propagator is conjectured, showing that it becomes singular at a special point. statistical physics dynamical systems quantum chaos statistična fizika dinamični sistemi kvantni kaos true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-18 14:46:25 2024-11-18 14:46:26 2024-11-22 14:56:45 0000-00-00 00:00:00 2024 0 0 Str. 054204-1-054204-13 iss. 5 Vol. 110 2024 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 530.145 2470-0045 10.1103/PhysRevE.110.054204 215432451 2408.06307v3.pdf 2408.06307v3.pdf 1 FDE56468B76192E37CA7C33F02365FF5 fd5e140d493cef77fbe317003e80eb33048f1468e5338232e88bd6534e289277 43196b27-a5b3-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195809 https://journals.aps.org/pre/abstract/10.1103/PhysRevE.110.054204 0 f4f26e9e-a8b7-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196025 Fakulteta za matematiko in fiziko 0 0 0
