First-principles phase diagram of an interacting ionic chain
Jamin Kidd, Ruiqi Zhang, Shao-Kai Jian +1
The widely-used Kohn-Sham implementation of density functional theory (DFT) maps a system of interacting electrons onto an auxiliary non-interacting one and is presumably inaccurat…
Emergence of competing electronic states from non-integer nuclear charges
James W. Furness, Ruiqi Zhang, Jamin Kidd +1
Understanding many-electron phenomena with competing near-degenerate electronic states is of fundamental importance to chemistry and condensed matter physics. One of the most signi…
Competing Incommensurate Spin Fluctuations and Magnetic Excitations in Infinite-Layer Nickelate Superconductors
Christopher Lane, Ruiqi Zhang, Bernardo Barbiellini +4
The recently discovered infinite-layer nickelates show great promise in helping to disentangle the various cooperative mechanisms responsible for high-temperature superconductivity…
Peierls distortion driven multi-orbital origin of charge density waves in the undoped infinite-layer nickelate
Ruiqi Zhang, Christopher Lane, Johannes Nokelainen +5
Understanding similarities and differences between the cuprate and nickelate superconductors is drawing intense current interest. Competing charge orders have been observed recentl…
-electron and magnetic ordering effects in nickelates LaNiO and NdNiO: remarkable role of the cuprate-like band
Ruiqi Zhang, Christopher Lane, Bahadur Singh +5
Recent discovery of superconductivity in the doped infinite-layer nickelates has renewed interest in understanding the nature of high-temperature superconductivity more generally.…
Interpretations of ground-state symmetry breaking and strong correlation in wavefunction and density functional theories
John P. Perdew, Adrienn Ruzsinszky, Jianwei Sun +2
Strong correlations within a symmetry-unbroken ground-state wavefunction can show up in approximate density functional theory as symmetry-broken spin-densities or total densities,…
