An excitation matched local correlation approach to excited state specific perturbation theory
Rachel Clune, Eric Neuscamman
We develop a cubic scaling approach to excited-state-specific second order perturbation theory in which the completeness of a local correlation treatment is carefully matched betwe…

Studying excited-state-specific perturbation theory on the Thiel set
Rachel Clune, Jacqueline A. R. Shea, Tarini Hardikar +2
We explore the performance of a recently-introduced -scaling excited-state-specific second order perturbation theory (ESMP2) on the singlet excitations of the Thiel benchmarki…

An N-scaling excited-state-specific perturbation theory
Rachel Clune, Jacqueline A. R. Shea, Eric Neuscamman
We show that by working in a basis similar to that of the natural transition orbitals and using a modified zeroth order Hamiltonian, the cost of a recently-introduced perturbative…
