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…
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…
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…
Magnetically ordered yet topologically robust phases emerging in concurrent Kitaev spin liquids
Muhammad Akram, Aayush Vijayvargia, Hae-Young Kee +1
Spin-orbital generalizations of Kitaev model, such as Yao-Lee model, have attracted recent attention due to their enhanced stability of spin liquid phases against perturbations. Mo…
Altermagnets with topological order in Kitaev bilayers
Aayush Vijayvargia, Ezra Day-Roberts, Antia S. Botana +1
Building on recent advancements in altermagnetism, we develop a highly-frustrated magnetic model with Kitaev-like interactions that integrates key aspects of both quantum spin liqu…
Nematic heavy fermions and coexisting magnetic order in CeSiI
Aayush Vijayvargia, Onur Erten
Motivated by the recent discovery of magnetism and heavy quasiparticles in van der Waals material CeSiI, we develop an effective model that incorporates the conduction electrons re…
