20.500.12556/RUL-124030 Rigorous bounds on dynamical response functions and time-translation symmetry breaking Dynamical response functions are standard tools for probing local physics near the equilibrium. They provide information about relaxation properties after the equilibrium state is weakly perturbed. In this paper we focus on systems which break the assumption of thermalization by exhibiting persistent temporal oscillations. We provide rigorous bounds on the Fourier components of dynamical response functions in terms of extensive or local dynamical symmetries, i.e. extensive or local operators with periodic time dependence. Additionally, we discuss the effects of spatially inhomogeneous dynamical symmetries. The bounds are explicitly implemented on the example of an interacting Floquet system, specifically in the integrable Trotterization of the Heisenberg XXZ model. true false false Angleški jezik Angleški jezik Neznano 2020-12-21 12:26:50 2020-12-21 12:26:51 2022-09-04 03:57:14 0000-00-00 00:00:00 2020 0 0 18 str. art. no. 003 Vol. 9 Jul. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 530.145 2542-4653 10.21468/SciPostPhys.9.1.003 43040771 526154521 RAZ_Medenjak_Marko_2020.pdf RAZ_Medenjak_Marko_2020.pdf 1 82122C941578AAD539CE06AC87A42270 dc8368e13f63d6d9fa5ac9e947003333dbf7bd52e9253843cf8ad8b5c0e49107 7538d17f-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=139409 https://scipost.org/10.21468/SciPostPhys.9.1.003 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140138 Fakulteta za matematiko in fiziko 0 0 0
