Comment

The following relations always hold.

\[\text{norbs} = \text{npsin} * \text{nband}\]

\[\text{ncfgs} = 2^{\text{norbs}}\]

You have to ensure the value of norbs is compatible with nband, nspin and ncfgs. The quantum impurity solvers will not check and correct them automatically. So you have to setup them in the solver.ctqmc.in file explicitly.

See also nspin, nband, and norbs parameters for more details.
