20.500.12556/RUL-107410 Impenetrable SU(N) fermions in one-dimensional lattices We study SU(N) fermions in the limit of infinite on-site repulsion between all species. We focus on states in which every pair of consecutive fermions carries a different spin flavor. Since the particle order cannot be changed (because of the infinite on-site repulsion) and contiguous fermions have a different spin flavor, we refer to the corresponding constrained model as the model of distinguishable quantum particles. We introduce an exact numerical method to calculate equilibrium one-body correlations of distinguishable quantum particles based on a mapping onto noninteracting spinless fermions. In contrast to most many-body systems in one dimension, which usually exhibit either power-law or exponential decay of off-diagonal one-body correlations with distance, distinguishable quantum particles exhibit a Gaussian decay of one-body correlations in the ground state, while finite-temperature correlations are well described by stretched exponential decay. true false false Angleški jezik Angleški jezik Neznano 2019-04-11 14:35:01 2019-04-11 14:35:02 2022-08-19 03:49:24 0000-00-00 00:00:00 2018 0 0 Str. 042129-1-042129-12 no. 4 Vol. 98 2018 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 53 2469-9926 10.1103/PhysRevA.98.042129 32045863 2996836 RAZ_Zhang_Yicheng_i2018.pdf RAZ_Zhang_Yicheng_i2018.pdf 1 724D180216C26DEE97164D695F619F8D fa2ddd1ff1e5821d23b4d3db676f8f4860bb0f93be32b838405727e8080ca070 6d2f20b4-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118227 https://journals.aps.org/pra/abstract/10.1103/PhysRevA.98.042129 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140316 Fakulteta za matematiko in fiziko 0 0 0
