Abstract
Using an extended expression for the Landau-Lifshitz free-energy density we have computed order-parameter fluctuation eigenmodes for the triple hexago nal incommensurate charge-density-wave (ICDW) phase in 2H-TaSe2. Phasons an d amplitudons have been obtained for two particular directions and we have performed some numerical calculations.
