N2 - Electron gas in a wire connected to two terminals with potential drop is studied with the Schwinger-Keldysh formalism. Recent studies, where the current is enforced to flow with a Lagrange-multiplier term, demonstrated that the current enhances the one-particle-correlation function. We report that in our model, such enhancement is not guaranteed to occur, but conditional both on the potential drop and the positions where we observe the correlation function. That is, under a certain condition, spatially modulated pattern is formed in the wire owing to the nonequilibrium current. (C) 2000 Published by Elsevier Science B.V.
