Convergence of Møller-Plesset perturbation theory for excited reference states
Diana-Gabriela Oprea, Hugh G. A. Burton
Excited states in molecules can be difficult to investigate and generally require methods that are either computationally expensive or are not universally accurate. Recent research…
Spin-constrained Hartree-Fock and the generator coordinate method for the 2-site Hubbard model
Stijn De Baerdemacker, Amir Ayati, Hugh G. A. Burton +3
We present a mathematical analysis of the spin-constrained Hartree-Fock solutions (CHF) of the 2-site Hubbard model. The analysis sheds light on the spin symmetry breaking process…
Exact electronic states with shallow quantum circuits through global optimisation
Hugh G. A. Burton, Daniel Marti-Dafcik, David P. Tew +1
Quantum computers promise to revolutionise electronic simulations by overcoming the exponential scaling of many-electron problems. While electronic wave functions can be represente…
