Symmetry fractionalization in the gauge mean-field theory of quantum spin ice
Félix Desrochers, Li Ern Chern, Yong Baek Kim
Symmetry fractionalization is a ubiquitous feature of topologically ordered states that can be used to classify different symmetry-enriched topological phases and reveal some of th…
Competing quantum spin liquids, gauge fluctuations, and anisotropic interactions in a breathing pyrochlore lattice
Li Ern Chern, Yong Baek Kim, Claudio Castelnovo
We use the projective symmetry group analysis to classify the quantum spin liquids on the pyrochlore magnet with a breathing anisotropy. We find 40 spin liqu…
Geometrical frustration versus Kitaev interactions in BaCo(AsO)
Thomas Halloran, Félix Desrochers, Emily Z. Zhang +12
Recently, Co-based honeycomb magnets have been proposed as promising candidate materials to host the Kitaev spin liquid state. One of the front-runners is BaCo(AsO) (BC…
Collective magnetic Higgs excitation in a pyrochlore ruthenate
Dirk Wulferding, Junkyeong Kim, Mi Kyung Kim +13
The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, wi…
