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

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
