20.500.12556/RUL-113074 Dynamical phase diagram of a quantum Ising chain with long-range interactions We investigate the effect of short-range correlations on the dynamical phase diagram of quantum many-body systems with long-range interactions. Focusing on Ising spin chains with power-law decaying interactions and accounting for short-range correlations by a cluster mean field theory we show that short-range correlations are responsible for the emergence of a chaotic dynamical region. Analyzing the fine details of the phase diagram, we show that the resulting chaotic dynamics bears close analogies with that of a tossed coin. quantum mechanics statistical mechanics kvantna mehanika statistična mehanika true false false Angleški jezik Slovenski jezik Neznano 2019-12-02 09:37:27 2019-12-02 09:37:28 2022-08-25 03:52:33 0000-00-00 00:00:00 2019 0 0 Str. 180402-1-180402-5 iss. 18 Vol. 100 2019 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.93 2469-9950 10.1103/PhysRevB.100.180402 3389796 2997348 RAZ_Piccitto_Giulia_2019.pdf RAZ_Piccitto_Giulia_2019.pdf 1 16C4AE9177C1A03F5953C44F1B627FC9 63124feb0e1ce9094fb9268336b64820ce839d7fc1649ac655d62b6e3fc7167e 04deddc2-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125044 https://journals.aps.org/prb/abstract/10.1103/PhysRevB.100.180402 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140300 Fakulteta za matematiko in fiziko 0 0 0
