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…
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…
Impurity-induced phonon thermal Hall effect in the antiferromagnetic phase of Sr2IrO4
Amirreza Ataei, Gael Grissonnanche, Marie-Eve Boulanger +4
A thermal Hall effect is observed in an increasing number of insulators often attributed to phonons, but the underlying mechanism is in most cases unknown. A coupling of phonons to…
Electrons with Planckian scattering obey standard orbital motion in a magnetic field
A. Ataei, A. Gourgout, G. Grissonnanche +14
In various "strange" metals, electrons undergo Planckian dissipation, a strong and anomalous scattering that grows linearly with temperature, in contrast to the quadratic temperatu…
Thermal Hall conductivity of electron-doped cuprates
Marie-Eve Boulanger, Gaël Grissonnanche, Étienne Lefrançois +5
Measurements of the thermal Hall conductivity in hole-doped cuprates have shown that phonons acquire chirality in a magnetic field, both in the pseudogap phase and in the Mott insu…
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…
Effect of pressure on the pseudogap and charge-density-wave phases of the cuprate LaNdSrCuO probed by thermopower measurements
A. Gourgout, A. Ataei, M. -E. Boulanger +9
We report thermopower measurements under hydrostatic pressure on the cuprate superconductor LaNdSrCuO (Nd-LSCO), at low-temperature in the normal state ac…
Transport signatures of the pseudogap critical point in the cuprate superconductor BiSrLaCuO
M. Lizaire, A. Legros, A. Gourgout +16
Five transport coefficients of the cuprate superconductor BiSrLaCuO were measured in the normal state down to low temperature, reached by applying a magneti…
Thermal Hall conductivity in the cuprate Mott insulators NdCuO and SrCuOCl
Marie-Eve Boulanger, Gaël Grissonnanche, Sven Badoux +11
The heat carriers responsible for the unexpectedly large thermal Hall conductivity of the cuprate Mott insulator LaCuO were recently shown to be phonons. However, the mecha…
Phonons become chiral in the pseudogap phase of cuprates
G. Grissonnanche, S. Thériault, A. Gourgout +11
The nature of the pseudogap phase of cuprates remains a major puzzle. One of its new signatures is a large negative thermal Hall conductivity , which appears for doping…
Field-angle dependence of sound velocity in the Weyl semimetal TaAs
F. Laliberté, F. Bélanger, N. L. Nair +5
The elastic modulus of a single crystal of the Weyl semimetal TaAs was investigated by measuring relative changes in the sound velocity under application of a magnetic fie…
Transport signatures of surface states in a Weyl semimetal: evidence of field driven Fermi arc interferometry
Nityan L. Nair, Marie-Eve Boulanger, Francis Laliberté +8
A signature property of Weyl semimetals is the existence of topologically protected surface states - arcs in momentum space that connect Weyl points in the bulk. However, the prese…
Pseudogap phase of cuprate superconductors confined by Fermi surface topology
N. Doiron-Leyraud, O. Cyr-Choinière, S. Badoux +15
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which…
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…
