Full-frequency GW from Cayley-transformed self-energy moments
Marcus K. Allen, George H. Booth
The dynamical GW self-energy approximation is a key computational tool to provide the fundamental spectrum of electronic systems. We reformulate this approximation, representing th…

Self-consistent GW via conservation of spectral moments
Oliver J. Backhouse, Marcus K. Allen, Charles C. J. Scott +1
We expand on a recently introduced alternate framework for simulation of charged excitations [Scott et. al., J. Chem. Phys., 158, 124102 (2023)], based around the conservation…
