QDK/Chemistry: A Modular Toolkit for Quantum Chemistry Applications
Nathan A. Baker, Brian Bilodeau, Chi Chen +23
We present QDK/Chemistry, a software toolkit for quantum chemistry workflows targeting quantum computers. The toolkit addresses a key challenge in the field: while quantum algorith…
Relativistic Core-Valence-Separated Molecular Mean-Field Exact-Two-Component Equation-of-Motion Coupled Cluster Theory: Applications to L-edge X-ray Absorption Spectroscopy
Samragni Banerjee, Run R. Li, Brandon C. Cooper +4
L-edge X-ray absorption spectra for first-row transition metal complexes are obtained from relativistic equation-of-motion singles and doubles coupled-cluster (EOM-CCSD) calculatio…
Relativistic Two-component Double Ionization Potential Equation-of-Motion Coupled Cluster with the Dirac--Coulomb--Breit Hamiltonian
Run R. Li, Stephen H. Yuwono, Marcus D. Liebenthal +3
We have implemented relativistic formulations of DIP-EOMCCSD and DIP-EOMCCSDT within the 1eX2C and DC-, DCG-, and DCB-X2C frameworks. Direct comparisons against full 4c-DIP-EOMCCSD…
Automated Quantum Chemistry Code Generation with the pq Package
Marcus D. Liebenthal, Stephen H. Yuwono, Lauren N. Koulias +3
This article summarizes recent updates to the pq package, which is a C++ accelerated Python library for generating equations and computer code corresponding to singly-ref…
Two-component relativistic equation-of-motion coupled cluster for electron ionization
Stephen H. Yuwono, Run R. Li, Tianyuan Zhang +2
We present an implementation of relativistic ionization-potential (IP) equation-of-motion coupled-cluster (EOMCC) with up to 3-hole--2-particle (3h2p) excitations that makes use of…
