Exact quantum spin liquids with topological order on maple-leaf and trellis lattices
Li Ern Chern, Roderich Moessner, Claudio Castelnovo
We construct spin models with bond-dependent anisotropic interactions on the penta-coordinated maple-leaf and trellis lattices, which yield exact quantum spin liquid…
Hydrodynamic Memory and Long-Time Tails in Clean Frustrated Magnets
Yufei Pei, Claudio Castelnovo, Roderich Moessner
In a simple, clean but constrained magnet, we identify a self-interacting random walk with memory. For the motion of a single monopole -- a fractionalized quasiparticle in spin ice…
Mapping vortices to anyons in toric code phases of generalized Kitaev models
Li Ern Chern, Roderich Moessner, Claudio Castelnovo
We present a comprehensive theory of mapping flux excitations, or vortices, to electric and magnetic particles in the toric code phases of generalizations of the Kitaev honeycomb m…
Kinetic kagome magnetism: from self-trapping RVB polarons to semiclassical correlations
Yufei Pei, Shuai A. Chen, Claudio Castelnovo +1
To gain deeper insight into the role of hole kinetics in determining magnetism in highly frustrated doped Mott insulators, we consider the single-hole counter-Nagaoka problem on th…
Unstable periodic orbits galore and quantum hyperscarring in highly frustrated magnets
Andrea Pizzi, Claudio Castelnovo, Johannes Knolle
Highly frustrated magnets, with their macroscopically-degenerate classical ground states and massively-entangled quantum spin liquid phases, have been pivotal to the development of…
