Two-exciton bound state quantum self-trapping in an extended star graph
An attractive Bose-Hubbard model is applied for describing quantum self-trapping in an extended star graph. In the strong coupling limit and when two excitons are created on the core of the star, the dynamics is dominated by pair states whose properties are governed by the branch number N. When N =...
