Electronic mean free path of the cuprate superconductor BiSrCaCuO from thermal Hall conductivity
Emma Campillo, Manel Mezidi, Lu Chen +6
We use thermal transport to access the electronic mean free path of -wave quasiparticles in one of the most widely studied cuprate superconductors, BiSrCaCuO…
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…
Role of magnetic ions in the thermal Hall effect of the paramagnetic insulator TmVO
Ashvini Vallipuram, Lu Chen, Emma Campillo +9
In a growing number of materials, phonons have been found to generate a thermal Hall effect, but the underlying mechanism remains unclear. Inspired by previous studies that reveale…
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…
