Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
Mikołaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
We derive a controlled low-energy effective theory for the three-band Emery model on the Lieb lattice near (n=2) filling. Starting from the positive charge-transfer regime, a seque…
Evidence for Many-Body States in NiPS Revealed by Angle-Resolved Photoelectron Spectroscopy
Miłosz Rybak, Benjamin Pestka, Biplab Bhattacharyya +11
We present -ARPES spectra of the Mott-insulating van der Waals antiferromagnet NiPS. Signatures of strong correlations -- such as the onset of atomic or atomic-ligand multip…
Probing the band structure of the strongly correlated antiferromagnet NiPS3 across its phase transition
Benjamin Pestka, Biplab Bhattacharyya, Milosz Rybak +19
NiPS3 is an exfoliable van-der-Waals intralayer antiferromagnet with zigzag-type spin arrangement. It is distinct from other TMPS3 (TM: transition metal) materials by optical excit…
Neodymium ions as charge reservoir in NdNiO: from lack of long range order to electron-doping-induced antiferromagnetism
Adam Kłosiński, Roman Drachynskyi, Krzysztof Wohlfeld +1
We study magnetism in the electron-doped infinite-layer nickelate NdNiO. We perform an unrestricted Hartree-Fock calculation for a tight-binding model which contains both nicke…
Exploring d-Wave Magnetism in Cuprates from Oxygen Moments
Ying Li, Valentin Leeb, Krzysztof Wohlfeld +2
The antiferromagnetic parent phase of high-T cuprates has been established as a Néel state of copper moments, but early work pointed out the important role of ligand oxygen orb…
Mobile orbitons in CaCuO: crucial role of the Hund's exchange
Roberto Fumagalli, Jonas Heverhagen, Davide Betto +9
We investigate the Cu edge resonant inelastic x-ray scattering (RIXS) spectra of a quasi-1D antiferromagnet CaCuO. In addition to the magnetic excitations, which are…
