Dynamical pseudopotentials with sum-over-poles representation reproduce all-electron scattering over wide energy ranges and enable a consistent many-body treatment of all-electron atoms, pseudo-atoms, and solids.
Charge self-consistent eDMFT with uniform U=6 eV for metals and U=10 eV for insulators yields spectral functions in excellent agreement with photoemission experiments across ABO3 compounds (A=Ca,Sr,La; B=V-Ni).
Quantum DMFT framework combining Gaussian subspace state representation with compressed circuits for Green's functions, shown to converge in simulation and run on 8-qubit IBM hardware.
