Ab initio quantum many-body description of superconducting trends in the cuprates
Zhi-Hao Cui, Junjie Yang, Johannes Tölle +9
Using a systematic ab initio quantum many-body approach that goes beyond low-energy models, we directly compute the superconducting pairing order and estimate the pairing gap of se…
General Quantum Alchemical Free Energy Simulations via Hamiltonian Interpolation
Chenghan Li, Xing Zhang, Garnet Kin-Lic Chan
We present an implementation of alchemical free energy simulations at the quantum mechanical level by directly interpolating the electronic Hamiltonian. The method is compatible wi…
Introducing GPU-acceleration into the Python-based Simulations of Chemistry Framework
Rui Li, Qiming Sun, Xing Zhang +1
We introduce the first version of GPU4PySCF, a module that provides GPU acceleration of methods in PySCF. As a core functionality, this provides a GPU implementation of two-electro…
Performant Automatic Differentiation of Local Coupled Cluster Theories: Response Properties and Ab Initio Molecular Dynamics
Xing Zhang, Chenghan Li, Hong-Zhou Ye +2
In this work, we introduce a differentiable implementation of the local natural orbital coupled cluster (LNOCC) method within the automatic differentiation framework of the PySCFAD…
