摘要：

We consider the van der Waals interaction for systems carrying a nonzero current. We show that in simple cases like two parallel wires or sheets, the van der Waals attraction increases quadratically with the difference between the currents in the two subsystems. This implies a nonzero current drag at zero temperature, a new effect that could be detected experimentally.
