What Does UCCN Stand For?

UCCN stands for Unitary Coupled Cluster Truncated To Nth Order

UCCN, or Unitary Coupled Cluster Truncated To Nth Order, is a computational method in quantum chemistry that extends traditional coupled cluster techniques by employing unitary transformations. This approach effectively captures electron correlation effects by truncating the coupled cluster series at a specified order, denoted by N. UCCN provides a balance between computational efficiency and accuracy, making it suitable for the study of many-body quantum systems and facilitating the analysis of excited states and dynamic phenomena in molecular systems.
