英文摘要	we demonstrate in theory that it is possible to all-electrically manipulate the rkky interaction in a quasi-one-dimensional electron gas embedded in a semiconductor heterostructure, in the presence of rashba and dresselhaus spin-orbit interaction. in an undoped semiconductor quantum wire where intermediate excitations are gapped, the interaction becomes the short-ranged bloembergen-rowland superexchange interaction. owing to the interplay of different types of spin-orbit interaction, the interaction can be controlled to realize various spin models, e.g., isotropic and anisotropic heisenberg-like models, ising-like models with additional dzyaloshinsky-moriya terms, by tuning the external electric field and designing the crystallographic directions. such controllable interaction forms a basis for quantum computing with localized spins and quantum matters in spin lattices.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-28t13:28:19z no. of bitstreams: 1 electrically controllable rkky interaction in semiconductor quantum wires.pdf: 222456 bytes, checksum: 723b18c7c5384cdde88e084be7af8e21 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-28t13:49:47z (gmt) no. of bitstreams: 1 electrically controllable rkky interaction in semiconductor quantum wires.pdf: 222456 bytes, checksum: 723b18c7c5384cdde88e084be7af8e21 (md5); made available in dspace on 2010-04-28t13:49:47z (gmt). no. of bitstreams: 1 electrically controllable rkky interaction in semiconductor quantum wires.pdf: 222456 bytes, checksum: 723b18c7c5384cdde88e084be7af8e21 (md5) previous issue date: 2010; nsfc 60525405 10874175 hk rgc cuhk/401906 hku 10/crf/08 cn yang visiting program; 其它
