Generalized nonorthogonal matrix elements for arbitrary excitations
Hugh G. A. Burton
Electronic structure methods that exploit nonorthogonal Slater determinants face the challenge of efficiently computing nonorthogonal matrix elements. In a recent publication, H. G…
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…
Complex analysis of divergent perturbation theory at finite temperature
Yi Sun, Hugh G. A. Burton
We investigate the convergence properties of finite-temperature perturbation theory by considering the mathematical structure of thermodynamic potentials using complex analysis. We…
Energy Landscape of State-Specific Electronic Structure Theory
Hugh G. A. Burton
State-specific approximations can provide an accurate representation of challenging electronic excitations by enabling relaxation of the electron density. While state-specific wave…
