摘要：
Nontopological spatially localized time periodic excitations - coined discrete breathers - are generic solutions for lattice Hamiltonians. I present recent results including the spatial decay of discrete breathers in systems with interactions decaying algebraically in space, the properties of the static deformation accompanying a breather excitation in low-symmetry lattice Hamiltonians with Goldstone modes, nonzero energy thresholds in lattice dimensions d greater than or equal to 2, models with analytic solutions and compact solutions. Finally I will discuss several experimental applications.
