20.500.12556/RUL-95809 Fractality in nonequilibrium steady states of quasiperiodic systems We investigate the nonequilibrium response of quasiperiodic systems to boundary driving. In particular, we focus on the Aubry-André-Harper model at its metal-insulator transition and the diagonal Fibonacci model. We find that opening the system at the boundaries provides a viable experimental technique to probe its underlying fractality, which is reflected in the fractal spatial dependence of simple observables (such as magnetization) in the nonequilibrium steady state. We also find that the dynamics in the nonequilibrium steady state depends on the length of the chain chosen: generic length chains harbour qualitatively slower transport (different scaling exponent) than Fibonacci length chains, which is in turn slower than in the closed system. We conjecture that such fractal nonequilibrium steady states should arise in generic driven critical systems that have fractal properties. condensed matter physics nonequilibrium dynamics quantum systems fractals fizika kondenzirane snovi neravnovesna dinamika kvantni sistemi fraktali true false false American Physical Society Angleški jezik Slovenski jezik American Physical Society Znanstveno delo 2017-09-21 13:21:32 2017-09-21 13:21:32 2022-08-10 06:55:47 0000-00-00 00:00:00 2017 0 0 Str. 032130-1-032130-11 iss. 3 Vol. 96 2017 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2470-0045 10.1103/PhysRevE.96.032130 3128164 2048366611 RAZ_Varma_Vipin_Kerala_i2017.pdf RAZ_Varma_Vipin_Kerala_i2017.pdf 1 3C6376E3C11FAFB61152DE9F8DF6E65A ddbbaef226261d77daf71691eae730808fff1d689fd97c1162e5a0684ead61a3 4b9b5570-a1b5-11eb-a523-00155dcfd717 20.500.12556/rul/3ad83d0d-2362-4785-b30e-edf5c052bd64 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=111585 https://journals.aps.org/pre/abstract/10.1103/PhysRevE.96.032130 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104450 Fakulteta za matematiko in fiziko 0 0 0
