What Does BWCC Stand For?

BWCC stands for Brillouin Wigner Coupled Cluster Theory

BWCC, or Brillouin Wigner Coupled Cluster Theory, is a sophisticated quantum many-body theory utilized in computational chemistry and physics. It extends traditional coupled cluster methods by incorporating non-perturbative effects through the Brillouin-Wigner transformation, enhancing the accuracy of electronic structure calculations for complex molecular systems. BWCC effectively captures correlation effects, making it a valuable tool for studying ground and excited states in quantum many-body systems.
