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…
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…
Electric field driven spin textures in heavy fermion van der Waals magnets
Aayush Vijayvargia, Hao Zhang, Kipton Barros +2
The recently discovered van der Waals material CeSiI exhibits both heavy fermion behavior and spiral order with strong magnetic anisotropy which makes it a potential host for topol…
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…
Topological and magnetic phase transitions in the bilayer Kitaev-Ising model
Aayush Vijayvargia, Urban F. P. Seifert, Onur Erten
We investigate the phase diagram of a bilayer Kitaev honeycomb model with Ising interlayer interactions, deriving effective models via perturbation theory and performing Majorana m…
Magnetic fragmentation and fractionalized Goldstone modes in a bilayer quantum spin liquid
Aayush Vijayvargia, Emilian Marius Nica, Roderich Moessner +2
We study the phase diagram of a bilayer quantum spin liquid model with Kitaev-type interactions on a square lattice. We show that the low energy limit is described by a -flux Hu…
Kitaev spin-orbital bilayers and their moiré superlattices
Emilian Nica, Muhammad Akram, Aayush Vijayvargia +2
We determine the phase diagram of a bilayer, Yao-Lee spin-orbital model with inter-layer interactions (J), for several stackings and moiré superlattices. For AA stacking, a gapped…
