Planar thermal Hall effect from phonons in cuprates
Lu Chen, Léna Le Roux, Gaël Grissonnanche +11
A surprising "planar" thermal Hall effect, whereby the field is parallel to the current, has recently been observed in a few magnetic insulators, and this has been attributed to ex…
Planar thermal Hall effect from phonons in a Kitaev candidate material
Lu Chen, Étienne Lefrançois, Ashvini Vallipuram +5
Kitaev materials are a promising platform for the realization of quantum spin liquid states. The thermal Hall effect has emerged as a potential probe of exotic excitations within s…
Planar parallel phonon Hall effect and local symmetry breaking
Quentin Barthélemy, Étienne Lefrançois, Lu Chen +5
Y-kapellasite [Y3Cu9(OH)19Cl8] is a frustrated antiferromagnetic insulator which remains paramagnetic down to a remarkably low Néel temperature of about 2 K. Having studied this ma…
Thermal Hall conductivity of electron-doped cuprates: Electrons and phonons
Marie-Eve Boulanger, Lu Chen, Vincent Oliviero +7
It has recently become clear that phonons generate a sizable thermal Hall effect in cuprates, whether they are undoped, electron-doped or hole-doped (inside the pseudogap phase). A…
Reconciling scaling of the optical conductivity of cuprate superconductors with Planckian resistivity and specific heat
B. Michon, C. Berthod, C. W. Rischau +7
Materials tuned to a quantum critical point display universal scaling properties as a function of temperature and frequency . A long-standing puzzle regarding cuprate superc…
Large Phonon Thermal Hall Conductivity in a Simple Antiferromagnetic Insulator
Lu Chen, Marie-Eve Boulanger, Zhi-Cheng Wang +2
Phonons are known to generate a thermal Hall effect in certain insulators, including oxides with rare-earth impurities, quantum paraelectrics, multiferroic materials and cuprate Mo…
