Assessing the Performance of Nonlinear Regression based Machine Learning Models to Solve Coupled Cluster Theory
Valay Agarawal, Samrendra Roy, Kapil K. Shrawankar +4
The iteration dynamics of the coupled cluster equations exhibits a synergistic relationship among the cluster amplitudes. The iteration scheme may be viewed as a multivariate discr…

An Approximate Coupled Cluster Theory via Nonlinear Dynamics and Synergetics: the Adiabatic Decoupling Conditions
Valay Agarawal, Chayan Patra, Rahul Maitra
The coupled cluster iteration scheme is analysed as a multivariate discrete-time map using nonlinear dynamics and synergetics. The nonlinearly coupled set of equations to determine…
