Discrete breathers in crystals

SV Dmitriev, EA Korznikova, YA Baimova… - Physics …, 2016 - iopscience.iop.org
It is well known that periodic discrete defect-containing systems support both traveling

Dark discrete breather modes in a monoaxial chiral helimagnet with easy-plane anisotropy

IG Bostrem, EG Ekomasov, J Kishine, AS Ovchinnikov… - Physical Review B, 2021 - APS
Nonlinearity and discreteness are two pivotal factors for an emergence of discrete breather
excitations in various media. We argue that these requirements are met in the forced …
