Chirality of topological gap solitons in bosonic dimer chains
arXiv:1607.01805 · doi:10.1103/PhysRevLett.118.023901
Abstract
We study gap solitons which appear in the topological gap of 1D bosonic dimer chains within the mean-field approximation. We find that such solitons have a non-trivial texture of the sublattice pseudospin. We reveal their chiral nature by demonstrating the anisotropy of their behavior in presence of a localized energy potential.
