WebThe density matrix embedding theory (DMET) is a numerical technique to solve strongly correlated electronic structure problems. By mapping the system to a fragment plus its … Webthe level-1 Wess-Zumino-Witten theory which describes the transition point. As we approach the transition from the critical phase to a ferromagnetic phase, new striking features appear at higher energies. Based on the findings, we argue that the spin-1 model is actually integrable just before this transition point. ---- Poster 2)
