Hi But I get the error message " Cannot evaluate I" using Sy=1/2/I*(Splus-Sminus) in models.xml and stop finally. What's the matter?' Do I need to edit/modify other items in models.xml or the running python or parameter file ?

Hi alps users and developers I want to simulate a lattice phase transition in external magnetic along x,y,z direction by using dmrg.I have to couple site operator with external magnetic field. But how to edit a complex number in the ALPS models.xml to get site operator Sy=1/2i(Splus-Sminus). Thanks in advance for your reply. -------------- next part -------------- An HTML attachment was scrubbed...

Just use I for i
