Transient localization from fractionalization: vanishingly small heat conductivity in gapless quantum magnets
Shi Feng, Penghao Zhu, Johannes Knolle +1
Several candidate materials for gapless quantum spin liquids exhibit a vanishing thermal conductivity, which is at odds with theoretical predictions. Here, we show that a suppresse…
Fate of Topological Dirac Magnons in van der Waals Ferromagnets at Finite Temperature
Rintaro Eto, Ignacio Salgado-Linares, Masahito Mochizuki +2
Dirac magnons, the bosonic counterparts of Dirac fermions in graphene, provide a unique platform to explore symmetry-protected band crossings and quantum geometry in magnetic insul…
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…
Order-by-disorder in magnets with frustrated spin interactions -- classical and large- limits via the spin functional integral
Peng Rao, Johannes Knolle
We investigate spin systems with extensive degeneracies in the classical ground states due to anisotropic frustrated spin interactions, where the degeneracy is not protected by sym…
Extrinsic contribution to bosonic thermal Hall transport
Léo Mangeolle, Johannes Knolle
Bosonic excitations like phonons and magnons dominate the low-temperature transport of magnetic insulators. Similar to electronic Hall responses, the thermal Hall effect (THE) of c…
Fractionalized Prethermalization in the One-Dimensional Hubbard Model
Anton Romen, Johannes Knolle, Michael Knap
Prethermalization phenomena in driven systems are generally understood via a local Floquet Hamiltonian obtained from a high-frequency expansion. Remarkably, recently it has been sh…
