WebOne-Site DMFT As we remark, only three parameters should be defined in order to apply the DMFT algorithm: ˆVi, G0, T. We study the paramagnetic solution of the DMFT in the square (and Bethe) lattice using the following: ^ Vi = Uni ↑ ni ↓, T = − μ, G0(ω) = { 1 N∑k[ω − ϵ(k)] − 1 Square lattice 2[ω + √ω2 − 1] − 1 Bethe lattice WebThe Bethe lattice is an infinite graph, where any two points are connected by a single path and each vertex has the same number of branches Z, as shown in Fig. 1 for …

Webdmft_bethe.ini An interesting phenomena called spin-freezing transition occurs in multi-orbital models [ P. Werner, E. Gull, M. Troyer and A. J. Millis, PRL 101, 166405 (2008) ]. The spin-freezing phenomena is signaled by a peculiar frequency dependence of the self-energy: Im Σ ( i ω n) ∝ ω n 0.5 . Web(1) obtained within DMFT for the Bethe lattice of infinite connectivity. Circles show the data points and the lines are guides to the eye. At half filling, the system is a band insulator at... peavey triumph 120 head
