GFCCLib: Scalable and Efficient Coupled-Cluster Green's Function Library for Accurately Tackling Many Body Electronic Structure Problems
Bo Peng, Ajay Panyala, Karol Kowalski +1
Coupled cluster Green's function (GFCC) calculation has drawn much attention in the recent years for targeting the molecular and material electronic structure problems from a many…
Quantum simulations employing connected moments expansions
Karol Kowalski, Bo Peng
Further advancement of quantum computing (QC) is contingent on enabling many-body models that avoid deep circuits and excessive use of CNOT gates. To this end, we develop a QC appr…
Real-time coupled-cluster approach for the cumulant Green's function
F. D. Vila, J. J. Rehr, J. J. Kas +2
Green's function methods within many-body perturbation theory provide a general framework for treating electronic correlations in excited states. Here we investigate the cumulant f…
Equation of motion coupled-cluster approach for intrinsic losses in x-ray spectra
John J. Rehr, Fernando D. Vila, Joshua J. Kas +3
We present an equation of motion coupled cluster approach for calculating and understanding intrinsic inelastic losses in core level x-ray absorption spectra (XAS). The method is b…
