“Development and Implementation of Hilbert-Space Multireference Tailored Coupled Cluster Method to Correct Bias in TCC Method for Dynamic Correlation in Degenerate Cases”

https://pubmed.ncbi.nlm.nih.gov/38095205

The abstract describes the development of a Hilbert-space multireference tailored coupled cluster method to address the bias in the original TCC method for treating dynamic correlation in degenerate cases, with an implementation and comparison on cyclobutadiene and tetramethyleneethane molecules, while assessing the sensitivity to orbital rotation.
