Dear all,
I use the exact diagonalization in ALPS to perform a calculation. I aim to know the distribution of several low-energy state. So I use the following statements:
'CONSERVED_QUANTUMNUMBERS' : 'N', 'N_total' :4, 'MEASURE_LOCAL[Local Density]':'n', 'NUMBER_EIGENVALUES' :1,
My model is a hardcore Bose-Hubbard one. However the output file only gives the eigenvalues in the momentum sector. I wonder why "measure_local" does not work. I appriciate your reply.
Sincerely,
