Tensor hypercontraction for self-consistent vertex corrected GW with static and dynamic screening; applications to molecules and solids with superexchange
Pavel Pokhilko, Chia-Nan Yeh, Miguel A. Morales +1
For molecules and solids, we developed efficient MPI-parallel algorithms for evaluating the second-order exchange term with bare, statically screened, and dynamically screened inte…
Relativistic Self-Consistent : Exact Two-Component Formalism with One-Electron Approximation for Solids
Chia-Nan Yeh, Avijit Shee, Qiming Sun +2
We present a formulation of relativistic self-consistent for solids based on the exact two-component formalism with one-electron approximation (X2C1e) and non-relativistic Cou…
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…
Testing the GFCCSD impurity solver on real materials within the self-energy embedding theory framework
Chia-Nan Yeh, Avijit Shee, Sergei Iskakov +1
We apply the Green's function coupled cluster singles and doubles (GFCCSD) impurity solver to realistic impurity problems arising for strongly correlated solids within the self-ene…
Nevanlinna Analytical Continuation
Jiani Fei, Chia-Nan Yeh, Emanuel Gull
Simulations of finite temperature quantum systems provide imaginary frequency Green's functions that correspond one-to-one to experimentally measurable real-frequency spectral func…
Electron correlations in cubic paramagnetic perovskite Sr(V,Mn)O -- Results from fully self-consistent self-energy embedding calculations
Chia-Nan Yeh, Sergei Iskakov, Dominika Zgid +1
In this work, we use the thermodynamically consistent and conserving self-energy embedding theory (SEET) to study the spectra of the prototypical undistorted cubic perovskites SrVO…
