The quasienergy band structure of an excitation in a regular lattice system is the spectral signature of the underlying lattice geometry. Here we study the formation of exotic quasienergy bandlike structures that follow not only from the lattice geom

Geometrical frustration in either classical or quantum lattice systems is a phenomenon in which the impossibility of satisfying simultaneously all constraints of the system Hamiltonian leads to complex structures with degeneracy of the ground state.

We study the superfluid behavior motion of interacting particles in a periodic potential subject to an external ac force. We observe a dynamical stabilization of the superfluid motion in the presence of ac forces around the boundary of the Brillouin

We discuss the effect of small perturbation on nodeless solutions of the nonlinear \Schrodinger\ equation in 1+1 dimensions in an external complex potential derivable from a parity-time symmetric superpotential that was considered earlier [Phys.~Rev.

We discuss the behavior of solitary wave solutions of the nonlinear Schr{\"o}dinger equation (NLSE) as they interact with complex potentials, using a four parameter variational approximation based on a dissipation functional formulation of the dynami

The interplay between nonlinearity and the band structure of pristine honeycomb lattices is systematically explored. For that purpose, a theory of collective excitations valid for the first Brillouin zone of the lattice is developed. Closed-form expr

The effect of instability on the propagation of solitary waves along one-dimensional discrete nonlinear Schrodinger equation with cubic nonlinearity is revisited. A self-contained quasicontinuum approximation is developed to derive closed-form expres

We study the diffusivity of solitons in noisy-coupled nonlinear oscillators. We consider an anharmonic atomic chain and a network of coupled RLC circuits with nonlinear capacitance and linear inductances and resistances. The solitons propagate in the
