Computationally efficient coupled-cluster approach to strongly correlated systems
The coupled-cluster family of methods is a highly accurate ab initio quantum chemistry and nuclear physics technique that uses an exponential cluster operator to explicitly account for weak and intermediate electron correlation. Applying it to strongly correlated systems is challenging due to a high computational cost. With the support of the Marie Skłodowska-Curie Actions programme, the NovACCA project aims to overcome this limitation. The new methods will be derived in the context of the spin-flip framework and validated against data on transition-metal complexes. They will then be implemented in studies of multi-centre transition-metal compounds and metal-organic frameworks, including the exploration of predictive modelling of magnetic materials, catalysts, and energy-relevant molecular systems.
Objective
The coupled-cluster family of methods is among the most reliable tools for treating weak and intermediate electron correlation. However, extensions of coupled-cluster theory to systems with strong correlation remain severely constrained by their high computational cost. I propose a novel accurate coupled-cluster approach (NovACCA) that overcomes these limitations by delivering a rigorous, balanced, and computationally affordable treatment of strong correlation.
The objectives include (1) derive and implement such methods within the spin-flip framework; (2) validate and benchmark the methods against state-of-the-art theoretical and experimental data on transition-metal complexes; (3) derive density matrices for electronic-structure analysis and molecular properties; and (4) extrapolate effective Hamiltonians for the accurate description of multi-center transition-metal compounds and metal–organic frameworks. NovACCA will lead the PI to explore new opportunities for predictive modeling of magnetic materials, catalysts, and energy-relevant molecular systems.
