Parameter: U
Definition
Averaged Coulomb interaction $U$.
Type
Float, double precision
Default value
4.0
Component
ALL, except for DAISY component.
Behavior
Actually, it is not used by the quantum impurity solvers to build the Coulomb interaction matrix. It will be output by the impurity solver as a reference. You can set it to any values. I forgot why I had designed this parameter.
In the BEGONIA, LAVENDER, and CAMELLIA components, it is used as an internal variable. Any user-defined value will be overridden.
