Query: Trilayer dusty plasma lattice: structure and dynamics   In this paper, we studied the structure and dynamics for a trilayer Yukawa
crystal. We firstly studied the optimal lattice structure by comparing lattice
interaction energy from different lattice distribution, after that, we did the
collective mode calculation and analyzed its eigenvectors, if the lattice
structure is stable, all the eigenvalues of the dynamical matrix should be
positive.
