Abstract
We report our study on unconventional charge density waves (UCDW) in
pure quasi-one dimensional conductors. We develop a new possible
mechanism of establishment of such a low temperature phase, in which
the driving force of the phase transition is the electron-phonon
interaction with coupling depending on both the momentum transfer
and the momentum of the scattered electron. Mean field treatment is
applied to obtain the optical conductivity. The inclusion of
collective modes causes significant change with respect to the
quasiparticle contribution, and leads to an effective mass which is
nonmonotonic in temperature as opposed to conventional charge
density waves.
