In the present work, we revisit a recently proposed and experimentally realized topological 2D lattice with periodically time-dependent interactions. We identify the fundamental solitons, previously observed in experiments and direct numerical …
In the present work we revisit the b-family model of peakon equations, containing as special cases the b=2 (Camassa-Holm) and b=3 (Degasperis-Procesi) integrable examples. We establish information about the point spectrum of the peakon solutions and …
We consider the existence and spectral stability of periodic multi-pulse solutions in Hamiltonian systems which are translation invariant and reversible, for which the fifth-order Korteweg-de Vries equation is a prototypical example. We use Lin's …
