Fermionic reduced density low-rank matrix completion, noise filtering, and measurement reduction in quantum simulations
Linqing Peng, Xing Zhang, Garnet Kin-Lic Chan
Fermionic reduced density matrices summarize the key observables in fermionic systems. In electronic systems, the two-particle reduced density matrix (2-RDM) is sufficient to deter…

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…
