Dynamical Cluster Approximation Study of Electron Localization in the Extended Hubbard Model
Hanna Terletska, Sergei Iskakov, Thomas Maier +1
We perform a detailed study of the phase transitions and mechanisms of electron localization in the extended Hubbard model using the dynamical cluster approximation on a $2\times 2…

Evaluation of two-particle properties within finite-temperature self-consistent one-particle Green's function methods: theory and application to GW and GF2
Pavel Pokhilko, Sergei Iskakov, Chia-Nan Yeh +1
One-particle Green's function methods can model molecular and solid spectra at zero or non-zero temperatures. One-particle Green's functions directly provide electronic energies an…
