Hi,teachers! I am first user of SSE in the ALPS software. I havs a simple but important question: 1, How is the susceptibility of simulation by using the SSE package converted to the susceptibility chi(unit: cm3) from the magnetic experiment? 2, What is the dimension of magnetization strength and field strength? Oe or T? Thanks a lot.

It is the units you use in the model - the same units you use for the couplings. The field term is -h*Sz, which has units of energy - the same unites as the J terms. To convert to the units you use, you compare to the equation you might be used to -g*mu_B*h*Sz - and this gives the conversion factor.
Similarly the susceptibility needs to be converted.
