英文摘要	for a triangular triple quantum dots (ttqds) ring with three terminals, when lowering one of the dot-lead coupling to realize the left-right (l-r) reflection symmetry coupling, the internal c-upsilon of the ttqds is well preserved in the absence of many-body effect for the symmetric distribution of the dot-lead coupling on the molecular orbits. in the presence of kondo effect, the decrement of one of the dot-lead couplings suppresses the inter-dot hopping. this happens especially for the coupled quantum dot (qd), which decouples with the other two ones gradually to form a localized state near the fermi level as a result, the internal dynamic symmetry of the ttqds ring is reduced to l-r reflection symmetry, and simultaneously, the linear conductance is lifted for the new forming molecular orbit near the fermi level; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-05t07:24:11z no. of bitstreams: 1 kondo effect in a triangular triple quantum dots ring with three terminals.pdf: 372235 bytes, checksum: 5b26a9d60ac45ee78005b88a1c3c8635 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-07-05t07:43:12z (gmt) no. of bitstreams: 1 kondo effect in a triangular triple quantum dots ring with three terminals.pdf: 372235 bytes, checksum: 5b26a9d60ac45ee78005b88a1c3c8635 (md5); made available in dspace on 2010-07-05t07:43:13z (gmt). no. of bitstreams: 1 kondo effect in a triangular triple quantum dots ring with three terminals.pdf: 372235 bytes, checksum: 5b26a9d60ac45ee78005b88a1c3c8635 (md5) previous issue date: 2010; this work was supported by the 973 program (2006cb921607, 2006cb604908) and the national natural science foundation of china (60625402, 60990313, 10804105).; 国内
