Spin-free exact two-component linear response coupled cluster theory for estimation of frequency-dependent second-order property
Sudipta Chakraborty, Tamoghna Mukhopadhyay, Achintya Kumar Dutta
We have presented the theory, implementation, and benchmark results for the one-electronic variant of spin-free exact two-component (SFX2C1e) linear response coupled cluster (LRCCS…
A relativistic third-order algebraic diagrammatic construction theory for electron detachment, attachment and excitation problems
Sudipta Chakraborty, Tamoghna Mukhopadhyay, Malaya K. Nayak +1
We present the theory and implementation of a highly efficient relativistic third-order algebraic diagrammatic construction [ADC(3)] method based on a four-component (4c) Dirac-Cou…
A Reduced Cost Four-Component Relativistic Unitary Coupled Cluster Method for Molecules
Kamal Majee, Tamoghna Mukhopadhyay, Malaya K. Nayak +1
We present a four-component relativistic unitary coupled cluster method for molecules. We have used commutator-based non-perturbative approximation using the ''Bernoulli expansion'…
