Parameter: nsing
Definition
The Hirsch-Fye algorithm is an auxiliary field quantum Monte Carlo algorithm. We implemented in the DAISY component in the iQIST software package. The nsing parameter is used to determine the number of auxiliary ising-like fields.
Type
Integer
Default value
1
Component
Only for the DAISY component.
Behavior
Determine the size of involved arrays.
The following relation always holds:
\[\text{nsing} = \frac{\text{norbs} * (\text{norbs} - 1)} { 2 }\]
So for single-band model, we obtain nband = 1, norbs = 2, nsing = 1.
