Thanks,
In all the cases, the measured quantities are static ones, aren't they?
Other than the Green's function(that are not implemented in some codes), am I right assuming that the definition of the observables is the same across the libraries?
Best regards,
Francisco

Hello,
I was wondering what is the definition that that the loop and directed
loop code return when the options:
'MEASURE[Correlations]' : True,
The Sz correlation function for spin models and the density correlation function for bosonic models.
'MEASURE[Structure Factor]' : True,
The Fourier transform of above.
'MEASURE[Green Function]' : True,
The S+ -- S- correlation function for spin models and b^\dag -- b correlation function for bosonic models.

Because I haven't been able to find them and I would like to know what
they are and more importantly what prefactors it has or it hasn't.
Thank you very much, Francisco Cordobes
