Emergent frustrated magnetism in strain-patterned graphene
Yu-Chiang Hsieh, Wen-Han Kao, Christophe De Beule +18
Geometrically frustrated magnetism conventionally arises from pre-existing magnetic moments on lattices whose geometry prevents their interactions from being simultaneously satisfi…
Flux-induced Aharonov-Bohm Oscillation in the Tunneling Spectroscopy of Kitaev Spin Liquids
Wen-Han Kao, Elio J. König
Identifying emergent flux excitations and signatures of their mutual statistics with itinerant Majorana fermions remains a central challenge in Kitaev spin liquids. We show that an…
Impurity quadrupole moments as local probes of flux sectors in the Kitaev spin liquid
Masahiro O. Takahashi, Wen-Han Kao, Satoshi Fujimoto +1
Emergent fluxes play a central role in the low-energy properties of quantum spin liquids (QSLs), where they encode the underlying gauge structure and fractionalization of spins. He…
Majorana Signatures in Planar Tunneling through a Kitaev Spin Liquid
Weiyao Li, Vitor Dantas, Wen-Han Kao +1
We propose a planar tunneling setup to probe vacancy-bound Majorana modes in the chiral Kitaev spin liquid. In this geometry, the inelastic tunneling conductance can be expressed d…
flux binding to higher-spin impurities in the Kitaev spin liquid
Masahiro O. Takahashi, Wen-Han Kao, Satoshi Fujimoto +1
Stabilizing fluxes in Kitaev spin liquids (KSLs) is crucial for both characterizing candidate materials and identifying Ising anyons. In this study, we investigate the effect…
Phonon dynamics in the site-disordered Kitaev spin liquid
Vitor Dantas, Wen-Han Kao, Natalia B. Perkins
The Kitaev honeycomb model provides a paradigmatic example of an exactly solvable quantum spin liquid (QSL), in which the spin degrees of freedom fractionalize into itinerant Major…
Topological transitions in the Yao-Lee spin-orbital model and effects of site disorder
Vladislav Poliakov, Wen-Han Kao, Natalia B. Perkins
The Yao-Lee model is an example of exactly solvable spin-orbital models that are generalizations of the original Kitaev honeycomb model with extra local orbital degrees of freedom.…
Dynamics of vacancy-induced modes in the non-Abelian Kitaev spin liquid
Wen-Han Kao, Gábor B. Halász, Natalia B. Perkins
We study the dynamical response of vacancy-induced quasiparticle excitations in the site-diluted Kitaev spin liquid with a magnetic field. Due to the flux-binding effect and the em…
Vacancy spectroscopy of non-Abelian Kitaev spin liquids
Wen-Han Kao, Natalia B. Perkins, Gábor B. Halász
Spin vacancies in the non-Abelian Kitaev spin liquid are known to harbor Majorana zero modes, potentially enabling topological quantum computing at elevated temperatures. Here, we…
Spin- and Flux-gap Renormalization in the Random Kitaev Spin Ladder
Wen-Han Kao, Natalia B. Perkins
We study the Kitaev spin ladder with random couplings by using the real-space renormalization group technique. This model is the minimum model in Kitaev systems that has conserved…
Disorder upon disorder: localization effects in the Kitaev spin liquid
Wen-Han Kao, Natalia B. Perkins
In recent years, several magnetic Mott insulators with strong spin-orbit couplings were suggested to be proximate to the Kitaev quantum spin liquid (QSL) whose one of the most exci…
Vacancy-induced low-energy density of states in the Kitaev spin liquid
Wen-Han Kao, Johannes Knolle, Gábor B. Halász +2
The Kitaev honeycomb model has attracted significant attention due to its exactly solvable spin-liquid ground state with fractionalized Majorana excitations and its possible materi…
Emergent Snake Magnetic Domains in Canted Kagome Ice
Wen-Han Kao, Gia-Wei Chern, Ying-Jer Kao
We study the two-dimensional kagome-ice model derived from a pyrochlore lattice with second- and third-neighbor interactions. The canted moments align along the local $\langle 111…
Generation of ice states through deep reinforcement learning
Kai-Wen Zhao, Wen-Han Kao, Kai-Hsin Wu +1
We present a deep reinforcement learning framework where a machine agent is trained to search for a policy to generate a ground state for the square ice model by exploring the phys…
Field-Induced Ordering in Dipolar Spin Ice
Wen-Han Kao, Peter Holdsworth, Ying-Jer Kao
We present numerical studies of dipolar spin ice in the presence of a magnetic field slightly tilted away from the [111] axis. We find a first-order transition from a kagome ice to…
