====== 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 =====

==== Input ====
<code Quanty 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 )
</code>

==== Result ====
<file Quanty_Output>
The chemical potential is	0
</file>
