The low temperature phase (LTP) of \ensuremathα\mathrm\text\ensuremath-(BEDT\mathrm\text\ensuremath-TTF)2KHg(SCN)4 salt is known for its surprising angular dependent magnetoresistance (ADMR), which has been studied intensively in the last decade. However, the nature of the LTP has not been understood until now. Here we analyze theoretically ADMR in unconventional (or nodal) charge-density wave (UCDW). In magnetic field the quasiparticle spectrum in UCDW is quantized, which gives rise to spectacular ADMR. The present model accounts for many striking features of ADMR data in \ensuremathα\mathrm\text\ensuremath-(BEDT\mathrm\text\ensuremath-TTF)2KHg(SCN)4.
