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…

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…

Random Transverse Field Effects on Magnetic Noise in Spin Systems
Yufei Pei, Claudio Castelnovo, Roderich Moessner
Motivated by experimental developments in non-Kramers spin ice materials and the unclear role of disorder therein, we study the impact of random transverse fields on the dynamics o…
