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 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…
Error stabilized logical qubits in qudit generalizations of the monitored Kitaev model
Aayush Vijayvargia, Ezra Day-Roberts, Onur Erten
Monitored dynamics in quantum circuits provide tunable platforms for the realization of novel non-equilibrium phases. Motivated by recent advances in monitored Kitaev circuits, we…
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…
