Some problems arising from electrostatic potential in CDW behavior
Part of the Lecture Notes in Physics book series (LNP, volume 217)
III. Dynamics of Charge Density Waves, Theory
Charge conservation property implies that if the current carried by the motion of a CDW is just
charges have to be considered as completely liked to the phase. A deformation of the phase has to be associated with an uncompensated charge. The consequences would be the replacement of the soft phason mode by a plasmon like mode, and of the elastic response by an electrostically screened one. Preliminary results on a microscopic calculation, show that the phason exists and does not carry a K component for the density of charges.
