摘要：
Recently we have shown that the striking angular dependent magnetoresistance in the low-temperature phase (LTP) of alpha-(BEDT-TTF)(2)KHg(SCN)(4) is consistently described in terms of unconventional charge density wave (UCDW). Here we investigate theoretically the thermoelectric power and the Nernst effect in unconventional density wave (UDW). The present results account consistently for the recent data of magnetothermopower in alpha-(BEDT-TTF)(2)KHg(SCN)(4) obtained by Choi [Phys. Rev. B 65, 205119 (2002)]. This confirms further our identification of LTP in this salt as UCDW. We propose also that the Nernst effect provides a clear signature of UDW.
