Unfortunately, the current version of Looper does not support models with complex matrix elements...

I was trying to use the looper algorithm, would this work? The Sx works fine and they should be equivalent...

You must be surge that your simulation is handling complex values...

Dear All,
I am struggling to define the Sy operator in my Hamiltonian. For the
'Spin' hamiltonian the Sx operator is defined as
<SITEOPERATOR name="Sx" site="x">
1/2*(Splus(x)+Sminus(x))
</SITEOPERATOR>
however when i attempted defining Sy in a similar manner:
<SITEOPERATOR name="Sy" site="x">
1j/2*(Splus(x)-Sminus(x))
</SITEOPERATOR>
the simulations halt without producing any output. Could you point me
how to implement the Sy operator properly and where am i making a
mistake?
In the long run I am attempting to apply two different fields in the XY
plane, GammaX along x and GammaY along y
Kind regards,
Stan
