Measurement Induced Dephasing and Suppression of Persistent Current in a Lattice Ring
Yong-Ping Zhang, Ying-Fang Gao, J. -Q. Liang
We investigate the effect of measurement on the persistent current density in a lattice ring penetrated by an Aharonov-Bohm flux and coupled to a quantum dot which is continuously…
