Two component Bose-Hubbard model
I'm trying to use DMRG to calculate some ground state properties of the two-component Bose-Hubbard model on a one-dimensional chain: H = -t \sum_{< i,j >} \left( a_i^+ a_j + b_i^+ b_j + H.c. \right) + \frac{U}{2} \sum_i [a_i^+ a_i (a_i^+ a_i - 1) + b_i^+ b_i (b_i^+ b_i - 1)] + U_{AB} \sum_i a_i^+ a_...
