High-Temperature Expansion (HTE)

What's about?

This is a C++ code for the High-Temperature Expansion (HTE) for arbitrary Heisenberg Hamiltonians written by Andre Lohmann (Kontakt: andre dot lohmann at st dot ovgu dot de or Johannes dot Richter at physik dot uni-magdeburg dot de). For more details, see H.-J. Schmidt, A. Lohmann, and J. Richter: 'Eighth-order high-temperature expansion for general Heisenberg Hamiltonians' Phys. Rev. B 84, 104443 (2011).
