20.500.12556/RUL-105775 Superdiffusion in one-dimensional quantum lattice models We identify a class of one-dimensional spin and fermionic lattice models which display diverging spin and charge diffusion constants, including several paradigmatic models of exactly solvable strongly correlated many-body dynamics such as the isotropic Heisenberg spin chains, the FermiHubbard model, and the t-J model at the integrable point. Using the hydrodynamic transport theory, we derive an analytic lower bound on the spin and charge diffusion constants by calculating the curvature of the corresponding Drude weights at half filling, and demonstrate that for certain lattice models with isotropic interactions some of the Noether charges exhibit super-diffusive transport at finite temperature and half filling. quantum statistical mechanics nonequilibrium statistical mechanics diffusion kvantna statistična mehanika neravnovesna statistična mehanika difuzija true false false Angleški jezik Slovenski jezik Neznano 2018-12-14 07:59:31 2018-12-14 07:59:32 2022-08-18 03:45:59 0000-00-00 00:00:00 2018 0 0 Str. 230602-1-230602-6 iss. 23 Vol. 121 2018 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.93 0031-9007 10.1103/PhysRevLett.121.230602 3275876 1282575 RAZ_Ilievski_Enej_i2018.pdf RAZ_Ilievski_Enej_i2018.pdf 1 ACD1C1FE4DFFE154CB5C0E40DEAFCC59 ea7c6615b5f1228d729aa6cd7c926df641aed4d407ea538174f2563c2557ad48 3629e91c-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116456 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.121.230602 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140323 Fakulteta za matematiko in fiziko 0 0 0
