%0 Journal Article %T The quantum dynamics of mesoscopic discrete-charge electric circuits %A F Kheirandish %A H Pahlavan %J Iranian Journal of Physics Research %D 2008 %I Isfahan University of Technology %X The quantum dynamics of a charged particle in an infinite chain of single-state quantum wells, in tight-binding approximation and under the action of an arbitrary time-dependent external field is investigated. The connection between the Hamiltonian description of this model and the Hamiltonian of a discrete-charge mesoscopic quantum circuit is elucidated. Based on this connection, the persistent current on a L-design nondissipative circuit is obtained. %K mesoscopic systems %K charge discreteness %K dynamical algebra %U http://ijpr.iut.ac.ir/browse.php?a_code=A-10-1-405&slc_lang=en&sid=1
