Mesonic excited states of magnetic monopoles in quantum spin ice
Olga Petrova
Spin ice magnetic monopoles are fractionalized emergent excitations in a class of frustrated magnets called spin ices. The classical spin ice model has an extensive number of groun…
A simple anisotropic three-dimensional quantum spin liquid with fracton topological order
Olga Petrova, Nicolas Regnault
We present a three-dimensional cubic lattice spin model, anisotropic in the direction, that exhibits fracton topological order. The latter is a novel type of topological…
Hydrogenic states of monopoles in diluted quantum spin ice
Olga Petrova, Roderich Moessner, S. L. Sondhi
We consider the effect of adding quantum dynamics to a classical topological spin liquid, with particular view to how best to detect its presence in experiment. For the Coulomb pha…
Projective symmetry of partons in Kitaev's honeycomb model
Paula Mellado, Olga Petrova, Oleg Tchernyshyov
Low-energy states of quantum spin liquids are thought to involve partons living in a gauge-field background. We study the spectrum of Majorana fermions of Kitaev's honeycomb model…
Unpaired Majorana modes on dislocations and string defects in Kitaev's honeycomb model
Olga Petrova, Paula Mellado, Oleg Tchernyshyov
We study the gapped phase of Kitaev's honeycomb model (a spin liquid) on a lattice with topological defects. We find that some dislocations and string defects carry unpaired…
Unpaired Majorana modes in the gapped phase of Kitaev's honeycomb model
Olga Petrova, Paula Mellado, Oleg Tchernyshyov
We study the gapped phase of Kitaev's honeycomb model (a Z_2 spin liquid) in the presence of lattice defects. We find that some dislocations and bond defects carry unpaired Majoran…
