mu

Returns the chemical potential used for the response / Green's function. We highly suggest to set the chemical potential to 0 and shift the onsite energies of the orbitals accordingly.

Example.Quanty

a1 = {0, -1,   0,   5,   6}
b1 = {  0.2, 0.2, 0.2, 0.2}
G1 = ResponseFunction.New( {a1,b1,mu=0,type="ListOfPoles", name="G1"} )
 
print( "The chemical potential is", G1.mu )

The chemical potential is	0
