Phys. Rev. Lett. 88, 116401 (2002) [4 pages]Coulomb Drag Shot Noise in Coupled Luttinger LiquidsReceived 22 August 2001; published 28 February 2002 Coulomb drag shot noise has been studied theoretically for 1D interacting electron systems, which are realized, e.g., in single-wall nanotubes. We show that under adiabatic coupling to external leads, the Coulomb drag shot noise of two coupled or crossed nanotubes contains surprising effects, in particular, a complete locking of the shot noise in the tubes. In contrast to Coulomb drag of the average current, the noise locking is based on a symmetry of the underlying Hamiltonian and is not limited to asymptotically small energy scales. © 2002 The American Physical Society URL:
