WebCluster-DMFT Lanczos Exact Diagonalization. A Lanczos based solver for the Cluster Dynamical Mean-Field Theory using the N_up:N_dw implementation in the normal phase (plus long-range magnetic or charge order). The set of modules compile into a top layer named CDMFT_ED.f90. WebJul 7, 2024 · The cluster DMFT of this problem retains aspects of Mott physics, as described in single site DMFT, and Slater physics. It does that by having two orbitals ( ( π , 0 ) and ( 0 , π ) ) exhibit a Mott transition while the remaining orbitals ( ( 0 , 0 ) and ( π , π ) ) undergo a band transition.

WebWe introduce a cluster DMFT (Dynamical Mean Field Theory) approach to study the normal state of the iron pnictides and chalcogenides. In the regime of moderate mass renormalizations, the self-energy is very local, justifying the success of single site DMFT for these materials and for other Hunds metals. http://nano-bio.ehu.es/files/Introduction_to_Cluster_DMFT_methods-Parcollet.pdf

WebWe do not attempt to do a cluster-DMFT calculation at this stage. Enter the correlated problems forming each unique correlated problem, separated by spaces (ex: 1,3 2,4 5-8): 1-4 All four V-atoms are equivalent, when described in their proper local coordinate system, hence we will be solving only one impurity problem.
