Electron vs. hole doping in infinite-layer nickelates: electronic structure, magnetism and correlations
Ezra Day-Roberts, Fabio Bernardini, Harrison LaBollita +3
The observation of superconductivity in undoped infinite-layer nickelates NiO ( = rare earth) challenges our current understanding and calls for a re-examination of the u…
Evidence for ferroaxial order in 1T-TiSe via elastoresistivity measurements
Qianni Jiang, Ezra Day-Roberts, Benito Gonzalez +5
The study of spontaneous symmetry breaking and electronic order is fundamental in condensed matter physics. Hidden order, symmetry-breaking states that elude conventional probes, p…
Tuning the magnetic properties of Kitaev materials via the antiferromagnetic proximity effect: Novel phases and application to an -RuCl/MnPS bilayer
Pedro M. Cônsoli, Ezra Day-Roberts, Johannes Knolle +2
In recent years, the increasing level of control over van der Waals (vdW) heterostructures has opened new routes to tune the properties of quantum materials. Motivated by these dev…
Electronic layer decoupling driven by density-wave order in LaNiO
Ziqiang Guan, Sophia F. R. TenHuisen, M. Tepie +14
We probe the density-wave transition of the trilayer nickelate LaNiO with polarization-resolved infrared spectroscopy. The low-energy electrodynamics is strongly ani…
An altermagnetic materials library in intercalated transition-metal dichalcogenides
Ezra Day-Roberts, Huan Wu, Onur Erten +1
Altermagnets represent a promising class of magnetic materials owing to their distinctive spin-split band structures in the absence of net magnetization. Here, we present a first-p…
Tuning entanglement phases and topological memory in the measurement-only Kitaev model with single and multi-qubit checks
Tushya Kalpada, Aayush Vijayvargia, Ezra Day-Roberts +1
Quantum circuits provide an emerging controllable platform to realize novel dynamical non-equilibrium phases including topologically ordered states. The Kitaev model has become a c…
