Iterative subspace algorithms for finite-temperature solution of Dyson equation
Pavel Pokhilko, Chia-Nan Yeh, Dominika Zgid
One-particle Green's functions obtained from the self-consistent solution of the Dyson equation can be employed in evaluation of spectroscopic and thermodynamic properties for both…
Exploring Coupled Cluster Green's function as a method for treating system and environment in Green's function embedding methods
Avijit Shee, Chia-Nan Yeh, Dominika Zgid
Within the self-energy embedding theory (SEET) framework, we study coupled cluster Green's function (GFCC) method in two different contexts: as a method to treat either the system…
Analytical Continuation of Matrix-Valued Functions: Carathéodory Formalism
Jiani Fei, Chia-Nan Yeh, Dominika Zgid +1
Finite-temperature quantum field theories are formulated in terms of Green's functions and self-energies on the Matsubara axis. In multi-orbital systems, these quantities are relat…
Material specific optimization of Gaussian basis sets against plane wave data
Yanbing Zhou, Emanuel Gull, Dominika Zgid
Since in periodic systems, a given element may be present in different spatial arrangements displaying vastly different physical and chemical properties, an elemental basis set tha…
Interpretation of multiple solutions in fully iterative GF2 and GW schemes using local analysis of two-particle density matrices
Pavel Pokhilko, Dominika Zgid
Due to non-linear structure, iterative Green's function methods can result in multiple different solutions even for simple molecular systems. In contrast to the wave-function metho…
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…
