Parameter: norbs

Definition

Number of correlated orbitals considered in the calculations.

Type

Integer

Default value

2

Component

ALL

Behavior

Determine the size of involved arrays.

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 and solver.hfqmc.in files explicitly.

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