Title

Hall effect in strongly correlated low-dimensional systems

Abstract We investigate the Hall effect in a quasi-one-dimensional system made of weakly coupled Luttinger liquids at half filling. Using a memory function approach, we compute the Hall coefficient as a function of temperature and frequency in the presence of umklapp scattering. We find a power-law correction to the free-fermion value (band value), with an exponent depending on the Luttinger parameter Kρ. At sufficiently high temperature or frequency, the Hall coefficient approaches the band value.
