Abstract
AbstractWe study the spin ordering of a quantum dot defined via magnetic barriers in an interacting quantum spin Hall edge. The spin‐resolved density–density correlation functions are computed. We show that strong electron interactions induce a ground state with a highly correlated spin pattern. The crossover from the liquid‐type correlations at weak interactions to the ground state spin texture found at strong interactions parallels the formation of a one‐dimensional Wigner molecule in an ordinary strongly interacting quantum dot.magnified imageA quantum dot, delimited by two magnetic barriers, embedded into a quantum spin Hall edge.(© 2013 WILEY‐VCH Verlag GmbH & Co.
