Stochastic many-body calculations of moiré states in twisted bilayer graphene at high pressures
Mariya Romanova, Vojtech Vlcek
Atomistic first principles many-body computational studies were so far limited by the system size. In this work, we apply and expand the stochastic GW method allowing calculations…

Decomposition and embedding in the stochastic self-energy
Mariya Romanova, Vojtěch Vlček
We present two new developments for computing excited state energies within the approximation. First, calculations of the Green's function and the screened Coulomb interaction…
