Ab initio quantum embedding at finite temperature with density matrix embedding theory
Laurence Giordano, Y. Stanley Tan, Zhi-Hao Cui +1
We present a finite-temperature extension of density matrix embedding theory (FT-DMET) for realistic crystalline systems. We describe a practical framework for constructing extende…

Towards an exact electronic quantum many-body treatment of Kondo correlation in magnetic impurities
Tianyu Zhu, Linqing Peng, Huanchen Zhai +3
The Kondo effect is a prototypical quantum phenomenon arising from the interaction between localized electrons in a magnetic impurity and itinerant electrons in a metallic host. Al…

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…
