Topological Impurity Bands
Arnab Seth, Itamar Kimchi
The effects of disorder on topological phases of matter are typically either preservation of topology or its destruction. For example, the quantum Hall effect's quantization and ch…
Arrested Relaxation in a Disorder-Free Coulomb Spin Liquid
Souvik Kundu, Arnab Seth, Sthitadhi Roy +2
We investigate Coulomb spin liquids in classical spin-3/2 ice and show that the enlarged on-site Hilbert space gives rise to a qualitatively new class of such phases. Beyond the co…
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…
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…
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…
Real-space chirality from crystalline topological defects in the Kitaev spin liquid
Fay Borhani, Arnab Seth, Itamar Kimchi
We show that certain crystalline topological defects in the gapless Kitaev honeycomb spin liquid model generate a chirality and Majorana fermion orbital magnetization that depends…
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…
