Dear all, I'm new to using ALPS and not entirely confident with setting up my model, which didn't appear to work at the moment. I'm interested in polaritonic system -- evanescently coupled-cavity system, each cavity containing a two-level atom. I have set up my model in the attached xml, Sminus and Splus are atomic projection operators and b are photon annihilation operator. The total number of excitations (atomic and photonic) is conserved. When I try running it, there is an bad_alloc error. Will anyone be kindly give me some pointers? Much appreciated and thank you very much in advance.
Regards, Chun-Hsu, Su
