Abstract

We consider the effect of imperfect nesting in quasi-one- dimensional unconventional density waves (DW's). The phase diagram is very close to those in a conventional DW's. The linear and non-linear aspects of the electric conductivity are discussed. At T = 0 the frequency dependent electric conductivity develops a small dip at low frequencies. The threshold electric field depends strongly on the imperfect nesting parameter, allowing us to describe very well the measured threshold electric field in the low temperature phase of the quasi-two-dimensional organic conductor, alpha-(BEDT- TTF)(2)KHg(SCN)(4).
