英文摘要	real-time detection of single electron tunneling through a t-shaped double quantum dot is simulated, based on a monte carlo scheme. the double dot is embedded in a dissipative environment and the presence of electrons on the double dot is detected with a nearby quantum point contact. we demonstrate directly the bunching behavior in electron transport, which leads eventually to a super-poissonian noise. particularly, in the context of full counting statistics, we investigate the essential difference between the dephasing mechanisms induced by the quantum point contact detection and the coupling to the external phonon bath. a number of intriguing noise features associated with various transport mechanisms are revealed.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-12-05t04:13:09z no. of bitstreams: 1 real-time counting of single electron tunneling through a t-shaped double quantum dot system.pdf: 316883 bytes, checksum: be704569ced83a49ba988452d6655ea4 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-12-05t04:20:04z (gmt) no. of bitstreams: 1 real-time counting of single electron tunneling through a t-shaped double quantum dot system.pdf: 316883 bytes, checksum: be704569ced83a49ba988452d6655ea4 (md5); made available in dspace on 2010-12-05t04:20:04z (gmt). no. of bitstreams: 1 real-time counting of single electron tunneling through a t-shaped double quantum dot system.pdf: 316883 bytes, checksum: be704569ced83a49ba988452d6655ea4 (md5) previous issue date: 2010; support from the national natural science foundation of china under grant no. 10904128, and the research grants council of the hong kong government (grant no. 604709) are gratefully acknowledged.; 国内
