Many-body perturbation theory provides a systematic route to describe electronic interactions beyond mean-field approaches by treating electron–electron correlation as a series of corrections to a ...

Perturbation theory underpins a broad spectrum of electronic structure methods by treating the full molecular Hamiltonian as a reference problem plus a small perturbing operator. Classic ...

An advanced mathematical model that can describe high-energy interactions between light and matter has been developed by two RIKEN researchers and a collaborator. The approach could be extended to ...

We're measuring all kinds of stuff at the Large Hadron Collider right now. The question we're addressing could be summed up as Does the Standard Model of particle physics work at LHC energies or not?

A recent study, led by Sabre Kais, Distinguished Professor of Chemistry and professor of electrical and computer engineering at Purdue University, and IBM’s Barbara Jones, used a quantum computer to ...
