Exact Nonequilibrium dc Shot Noise in Luttinger Liquids and Fractional Quantum Hall Devices
Exact Nonequilibrium dc Shot Noise in Luttinger Liquids and Fractional Quantum Hall Devices
A point contact in a Luttinger liquid couples left- and right-moving channels, producing shot noise. We calculate exactly the dc shot noise at zero temperature in the out-of-equilibrium steady state where current is flowing. Integrability ensures the existence of a quasiparticle basis where scattering is ``one by one'' off the …
