A tight-binding ladder model with moiré shift and Coulomb repulsion hosts an out-of-phase incommensurate CDW whose neutral acoustic phasons have speed set by the moiré parameter and inter-leg tunneling.
These modulations are smooth, harmonic, and chain-dependent, and can be accurately described by cosine functions with dis- tinct phases for each chain

Sliding phasons in Moir\'e Ladders
A tight-binding ladder model with moiré shift and Coulomb repulsion hosts an out-of-phase incommensurate CDW whose neutral acoustic phasons have speed set by the moiré parameter and inter-leg tunneling.
