Exploring the exact limits of the real-time equation-of-motion coupled cluster cumulant Green's functions
Bo Peng, Himadri Pathak, Ajay Panyala +3
In this paper, we analyze the properties of the recently proposed real-time equation-of-motion coupled-cluster (RT-EOM-CC) cumulant Green's function approach [J. Chem. Phys. 2020,…
Integrating Subsystem Embedding Subalgebras and Coupled Cluster Green's Function: A Theoretical Foundation for Quantum Embedding in Excitation Manifold
Bo Peng, Karol Kowalski
In this study, we introduce a novel approach to coupled-cluster Green's function (CCGF) embedding by seamlessly integrating conventional CCGF theory with the state-of-the-art sub-s…
QASMTrans: A QASM based Quantum Transpiler Framework for NISQ Devices
Fei Hua, Meng Wang, Gushu Li +8
The success of a quantum algorithm hinges on the ability to orchestrate a successful application induction. Detrimental overheads in mapping general quantum circuits to physically…
Impact of high-rank excitations on accuracy of the unitary coupled cluster downfolding formalism
Karol Kowalski, Bo Peng, Nicholas P. Bauman
In this paper, we evaluate the accuracy of the Hermitian form of the downfolding procedure utilizing the double unitary coupled cluster Ansatz (DUCC) on the H6 and H8 benchmark sys…
Real-time Equation-of-Motion Coupled-Cluster Cumulant Green's Function Method: Heterogeneous Parallel Implementation Based on the Tensor Algebra for Many-body Methods Infrastructure
Himadri Pathak, Ajay Panyala, Bo Peng +5
We report the implementation of the real-time equation-of-motion coupled-cluster (RT-EOM-CC) cumulant Green's function method [J. Chem. Phys. 152, 174113 (2020)] within the Tensor…
Triple excitations in Green's function coupled cluster solver for studies of strongly correlated systems in the framework of self-energy embedding theory
Avijit Shee, Chia-Nan Yeh, Bo Peng +2
Embedding theories became important approaches used for accurate calculations of both molecules and solids. In these theories, a small chosen subset of orbitals is treated with an…
