Fractionalization, emergent SU() symmetries, and fragmentation in layered quantum spin-orbital models
Pedro M. Cônsoli, Aayush Vijayvargia, Onur Erten
We propose a family of layered quantum spin-orbital models as a platform to study fractionalization, unconventional forms of symmetry-breaking order, and their possible coexistence…
Frustrated magnetic order in hybrid Kitaev spin-orbital models
Ivan Dutta, Aayush Vijayvargia, Anamitra Mukherjee +2
Spin-orbital generalization of Kitaev model provides a robust extension to the original Kitaev model. However, real materials often exhibit competing interactions that break exact…
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…
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…
Lessons from -RuCl3 for pursuing quantum spin liquid physics in atomically thin materials
Claudia Ojeda-Aristizabal, Xiaohu Zheng, Changsong Xu +20
Quantum spin liquids can arise from Kitaev magnetic interactions, and exhibit fractionalized excitations with the potential for a topological form of quantum computation. This revi…
