Advantage of Warm Starts for Electron-Phonon Systems on Quantum Computers
Arnab Adhikary, S. E. Skelton, Alberto Nocera +1
Simulating electron-phonon interactions on quantum computers remains challenging, with most algorithmic effort focused on Hamiltonian simulation and circuit optimization. In this w…

Extended Hubbard Model realized in 2D clusters of molecular anions
Oliver Tong, Katherine A. Cochrane, Bingkai Yuan +3
The Hubbard model, despite its simplicity, is remarkably successful at describing numerous many-body phenomena. However, due to the small class of problems which can be solved exac…

Angle-resolved photoemission intensity for multi-orbital bands: Complex interplay between the self-energy matrix and the optical matrix elements
Yau Chuen Yam, Mona Berciu, George A. Sawayzky
We use a simple one-dimensional two-band model with electron-phonon coupling to illustrate some of the complications that arise in multi-band systems when trying to extract a self-…
