Green/WeakCoupling: Implementation of fully self-consistent finite-temperature many-body perturbation theory for molecules and solids
Sergei Iskakov, Chia-Nan Yeh, Pavel Pokhilko +10
The accurate ab initio simulation of molecules and periodic solids with diagrammatic perturbation theory is an important task in quantum chemistry, condensed matter physics, and ma…
Quasiparticle and fully self-consistent GW methods: an unbiased analysis using Gaussian orbitals
Gaurav Harsha, Vibin Abraham, Ming Wen +1
We present a comparison of various approximations to self-consistency in the GW method, including the one-shot G0W0 method, different quasiparticle self-consistency schemes, and th…
Performance of wave function and Green's functions based methods for non equilibrium many-body dynamics
Cian C. Reeves, Gaurav Harsha, Avijit Shee +5
Theoretical descriptions of non equilibrium dynamics of quantum many-body systems essentially employ either (i) explicit treatments, relying on truncation of the expansion of the m…
Challenges with relativistic GW calculations in solids and molecules
Gaurav Harsha, Vibin Abraham, Dominika Zgid
For molecules and solids containing heavy elements, accurate electronic structure calculations require accounting not only for electronic correlations but also for relativistic eff…
Relativistic fully self-consistent for molecules: Total energies and ionization potentials
Vibin Abraham, Gaurav Harsha, Dominika Zgid
The fully self-consistent (sc) method with the iterative solution of Dyson equation provides a consistent approach for describing the ground and excited states without any…
