Landau Theory for Commensurate Charge-Density Waves Coupled to Uniform Lattice Deformation
Keiji Nakatsugawa, Toshiyuki Fujii, Satoshi Tanda
We formulate a minimal Landau theory for a charge-density wave (CDW) whose commensurability is defined with respect to a deformed lattice. The motivation is provided by recent obse…

Induced discommensurations in the lock-in transition of charge-density waves
Katsuhiko Inagaki, Satoshi Tanda
We studied McMillan's free energy of the lock-in transition in charge-density waves. The wave profiles near the critical value were obtained by numerical annealing. First, we demon…
