20.500.12556/RUL-130373 Full spectrum of the Liouvillian of open dissipative quantum systems in the Zeno limit We consider an open quantum system with dissipation, described by a Lindblad Master equation (LME). For dissipation locally acting and sufficiently strong, a separation of the relaxation timescales occurs, which, in terms of the eigenvalues of the Liouvillian, implies a grouping of the latter in distinct vertical stripes in the complex plane at positions determined by the eigenvalues of the dissipator. We derive effective LME equations describing the modes within each stripe separately, and solve them perturbatively, obtaining for the full set of eigenvalues and eigenstates of the Liouvillian explicit expressions correct at order 1/Γ included, where Γ is the strength of the dissipation. As an example, we apply our general results to quantum XYZ spin chains coupled, at one boundary, to a dissipative bath of polarization. quantum mechanics open quantum systems nonlinear dynamics kvantna mehanika odprti kvantni sistemi nelinearna dinamika true false false Angleški jezik Slovenski jezik Neznano 2021-09-14 08:56:00 2021-09-14 08:56:01 2022-09-09 04:16:08 0000-00-00 00:00:00 2021 0 0 Str. 190402-1-190402-6 iss. 19 Vol. 126 2021 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 530.145 0031-9007 10.1103/PhysRevLett.126.190402 76234499 RAZ_Popkov_Vladislav_2021.pdf RAZ_Popkov_Vladislav_2021.pdf 1 921242A395798682180B63921F6A1A78 efe9a4c520623a0e7c5604c15d711dafb1141260bcb1d4185891627e419c6f69 4805146d-1529-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147479 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.126.190402 0 c2d03f15-1528-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147470 Fakulteta za matematiko in fiziko 0 0 0
