摘要
A many-body theory is formulated for an inhomogeneous, interacting electron gas with electronic current. Electronic current is induced by a constraint condition imposed as a vector Lagrange multiplier. Constrained minimization of the total energy on the manifold of an arbitrary constant current leads to a many-electron Schrodinger equation with a complex, momentum-dependent potential. Constant current Hartree-Fock and Kohn-Sham approximations are formulated within the method and application to transport for quantum wires is developed. (C) 2001 Elsevier Science B.V.
