To this end, we prepare pure initial states with sharply peaked density profiles and calculate the time evolution of these nonequilibrium states, by using numerical forward-propagation approaches to chains as long as 20 sites. For a class of typical states, we find excellent agreement with linear-response theory and unveil the existence of remarkably clean charge diffusion in the regime of strong particle-particle interactions. We additionally demonstrate that, in the half-filling sector, this diffusive behavior does not depend on certain details of our initial conditions, i.e., it occurs for five different realizations with random and nonrandom internal degrees of freedom, single and double occupation of the central site, and displacement of spin-up and spin-down particles.}, cin = {JSC / JARA-HPC}, ddc = {530}, cid = {I:(DE-Juel1)JSC-20090406 / $I:(DE-82)080012_20140620$}, pnm = {511 - Computational Science and Mathematical Methods (POF3-511) / Manipulation and dynamics of quantum spin systems $(jjsc09_20120501)$}, pid = {G:(DE-HGF)POF3-511 / $G:(DE-Juel1)jjsc09_20120501$}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000408513700002}, pubmed = {pmid:28950562}, doi = {10.1103/PhysRevE.96.020105}, url = {https://juser.fz-juelich.de/record/837962}, }
