biquadratic terms in QMC
Dear all Thank you for developping ALPS. I am just trying to use ALPS QMC library. I have a simple question. Does any of ALPS QMC code for quantum spin models support the biquadratic terms (\vec{S}_i\cdot\vec{S}_j)^2 for S \geq 1?

I don't think that has been implemented in any code yet, except maybe Synge Todo's looper code On Aug 29, 2009, at 9:57 AM, Kazuo Hida wrote:

Dear Kazuo, indeed this is not implemented in the current SSE code, even though it shouldn't be too difficult to modify it in order to do so. Best Fabien Le 29 août 09 à 10:06, Matthias Troyer a écrit :

If so, I think it is helpful for many users to include biquadratic terms in the next issue of ALPS, because spin nematics is a hot subject.

No, that's not implemented in looper, too. Synge On 2009/08/29, at 17:06, Matthias Troyer wrote:
