Generation of chirality and orbital magnetization by Stone-Wales-type lattice defects in the Kitaev spin liquid
Arnab Seth, Fay Borhani, Itamar Kimchi
In this work we extend our study of the effect of certain crystallographic defects on the spin-1/2 Kitaev honeycomb spin liquid (arXiv:2511.19409), focusing on its gapless phase an…
Chiral spin liquid instability of the Kitaev honeycomb model with crystallographic defects
Arnab Seth, Fay Borhani, Itamar Kimchi
We study the spin-1/2 Kitaev honeycomb gapless spin liquid in the presence of Stone-Wales-type local lattice defects with odd-sided plaquettes. While the clean Kitaev model has no…
Disorder-induced spin-cluster magnetism in a doped kagome spin liquid candidate
Arnab Seth, Joseph C. Prestigiacomo, Aini Xu +6
The search for new quantum spin liquid materials relies on systems with strong frustration such as spins on an ideal kagome lattice. However, lattice imperfections can have substan…
Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state
Chaebin Kim, Sumedh Rathi, Naipeng Zhang +15
Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electri…
Chirality reversal at finite magnetic impurity strength and local signatures of a topological phase transition
Ruiqi Xu, Arnab Seth, Itamar Kimchi
We study the honeycomb lattice with a single magnetic impurity modeled by adding imaginary next-nearest-neighbor hopping ih on a single hexagon. This Haldane defect gives a topolog…
Emergent Inductance from Chiral Orbital Currents in a Bulk Ferrimagnet
Gang Cao, Hengdi Zhao, Yu Zhang +10
We report the discovery of a new form of inductance in the bulk ferrimagnet Mn3Si2Te6, which features strong spin-orbit coupling, large magnetic anisotropy, and pronounced magnetoe…
