Comment on Unusual violation of the Wiedemann-Franz law at ultralow temperatures in topological compensated semimetals
Kamran Behnia, Shiyan Li, Johnpierre Paglione +1
Recently, Wang et al. [1] reported on an unusual violation of Wiedemann-Franz law in three semimetals. We compare their observations to our observations in a variety of systems, wh…
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…
Seebeck coefficient in a cuprate superconductor: particle-hole asymmetry in the strange metal phase and Fermi surface transformation in the pseudogap phase
A. Gourgout, G. Grissonnanche, F. Laliberté +8
We report measurements of the Seebeck effect in both the plane () and along the axis () of the cuprate superconductor LaNdSrC…
Field-dependent heat transport in the Kondo insulator SmB6 : phonons scattered by magnetic impurities
M-E. Boulanger, F. Laliberté, M. Dion +12
The thermal conductivity of the Kondo insulator SmB was measured at low temperature, down to 70 mK, in magnetic fields up to 15 T, on single crystals grown using both the f…
The metallic transport of (TMTSF)_2X organic conductors close to the superconducting phase
Pascale Auban-Senzier, Denis Jérome, Nicolas Doiron-Leyraud +7
Comparing resistivity data of quasi-one dimensional superconductors (TMTSF)_2PF_6 and (TMTSF)_2ClO_4 along the least conducting c*-axis and along the high conductivity a -axis as a…
