I want to make a complex MPS, by introducing complex hopping in Bose-hubbard model.
There is some error...
Traceback (most recent call last):

numpy.core._exceptions.UFuncTypeError: Cannot cast ufunc 'add' output from dtype('complex128') to dtype('float64') with casting rule 'same_kind'

any one have any idea how to handel complex hamiltonian in OpenMPS ??

Thanks in advance.
