Collective modes in unconventional density waves

Year: 2003

Type: article

Abstract: We have investigated the collective modes of unconventional charge and spin density waves (UCDW, USDW) in quasi–one dimensional systems in random phase approximation. The density correlator regains its normal-state form due to the phase degree of freedom of the condensate. The possible effect of impurities is also discussed. From this, the current-current correlation function is evaluated through charge conservation. The spin susceptibility of USDW remains anisotropic in spite of the lack of any periodic modulation of the spin density. In UCDW, the spin response gets weaker in all three directions as the temperature is lowered.
