Role of three-particle vertex within dual fermion calculations
T. Ribic, P. Gunacker, S. Iskakov +5
We investigate the influence of self-energy diagrams beyond the two-particle vertex level within dual fermion theory. Specifically, we calculate the local three-particle vertex and…

Exact diagonalization solver for the extended dynamical mean-field theory
Darya Medvedeva, Sergei Iskakov, Friedrich Krien +2
We present an efficient exact diagonalization scheme for the extended dynamical mean-field theory and apply it to the extended Hubbard model on the square lattice with nonlocal cha…
