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…
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…
