Stability of compact breathers in translationally-invariant nonlinear chains with flat dispersion bands
Nathan Perchikov, O. V. Gendelman
The paper addresses compact oscillatory states (compact breathers) in translationally-invariant lattices with flat dispersion bands. The compact breathers appear in such systems ev…

Flat bands and compactons in mechanical lattices
Nathan Perchikov, O. V. Gendelman
Local configurational symmetry in lattice structures may give rise to stationary, compact solutions, even in the absence of disorder and nonlinearity. These compact solutions are r…
