Spatial Decay and Limits of Quantum Solute-Solvent Interactions
Guorong Weng, Amanda Pang, Vojtech Vlcek
Molecular excitations in the liquid-phase environment are renormalized by the surrounding solvent molecules. Herein, we employ the GW approximation to investigate the solvation eff…
Embedding vertex corrections in GW self-energy: theory, implementation, and outlook
Guorong Weng, Rushil Mallarapu, Vojtech Vlcek
The vertex function () within the Green's function formalism encapsulates information about all higher-order electron-electron interaction beyond those mediated by density fluct…
Dynamical downfolding for localized quantum states
Mariya Romanova, Guorong Weng, Arsineh Apelian +1
We introduce an approach to treat localized correlated electronic states in the otherwise weakly correlated host medium. Here, the environment is dynamically downfolded on the corr…
Reduced scaling of optimal regional orbital localization via sequential exhaustion of the single-particle space
Guorong Weng, Mariya Romanova, Arsineh Apelian +2
Wannier functions have become a powerful tool in the electronic structure calculations of extended systems. The generalized Pipek-Mezey Wannier functions exhibit appealing characte…
Efficient treatment of molecular excitations in the liquid phase environment via stochastic many-body theory
Guorong Weng, Vojtech Vlcek
Accurate predictions of charge excitation energies of molecules in the disordered condensed phase are central to the chemical reactivity, stability, and optoelectronic properties o…
Are multi-quasiparticle interactions important in molecular ionization?
Carlos Mejuto-Zaera, Guorong Weng, Mariya Romanova +4
Photo-emission spectroscopy directly probes individual electronic states, ranging from single excitations to high-energy satellites, which simultaneously represent multiple quasipa…
Quasiparticles and Band Transport in Organized Nanostructures of Donor-Acceptor Copolymers
Guorong Weng, Vojtěch Vlček
The performance of organic semiconductor devices is linked to highly-ordered nanostructures of self-assembled molecules and polymers. We employ many-body perturbation theory and st…
Stochastic many-body perturbation theory for Moiré states in twisted bilayer phosphorene
Jacob Brooks, Guorong Weng, Stephanie Taylor +1
A new implementation of stochastic many-body perturbation theory for periodic 2D systems is presented. The method is used to compute quasiparticle excitations in twisted bilayer ph…
