Abstract
We have investigated theoretically the thermoelectric power and the Nernst
effect in unconventional density waves (UDW). Due to the presence of magnetic
field, Landau levels are formed, and the low energy excitations change from gapless
to gapped. The present results
account consistently for the recent
data of magnetothermopower in
-(BEDT-TTF)
2KHg(SCN)
4 obtained
by Choi et al. (Phys. Rev. B, 65, 205119 (2002)).
This confirms further our identification of low temperature phase (LTP) in this salt as
UCDW.
Key words. density waves,
-(BEDT-TTF)
2KHg(SCN)
4, thermoelectric power.
