Multiple crossovers in interacting quantum wires
arXiv:cond-mat/0606016 · doi:10.1103/PhysRevB.74.115121
Abstract
We study tunneling of electrons into and between interacting wires in the spin-incoherent regime subject to a magnetic field. The tunneling currents follow power laws of the applied voltage with exponents that depend on whether the electron spins at the relevant length scales are polarized or disordered. The crossover length (or energy) scale is exponential in the applied field. In a finite size wire multiple crossovers can occur.
