No nematicity at the onset temperature of the pseudogap phase in the cuprate superconductor YBCO
G. Grissonnanche, O. Cyr-Choinière, J. Day +5
Electronic nematicity is the spontaneous loss of rotational symmetry in a metal, without breaking translational symmetry. In the cuprate superconductors, there is experimental evid…
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…
Anisotropy of the Seebeck Coefficient in the Cuprate Superconductor YBaCuO: Fermi-Surface Reconstruction by Bidirectional Charge Order
O. Cyr-Choinière, S. Badoux, G. Grissonnanche +11
The Seebeck coefficient of the cuprate YBaCuO was measured in magnetic fields large enough to suppress superconductivity, at hole dopings and $p =…

O. Cyr-Choinière, R. Daou, F. Laliberté +17
We use the Nernst effect to delineate the boundary of the pseudogap phase in the temperature-doping phase diagram of cuprate superconductors. New data for the Nernst coefficient $ν…
Fermi-surface transformation across the pseudogap critical point of the cuprate superconductor LaNdSrCuO
C. Collignon, S. Badoux, S. A. A. Afshar +8
The electrical resistivity and Hall coefficient R of the tetragonal single-layer cuprate Nd-LSCO were measured in magnetic fields up to T, large enough to access…

E. Hassinger, G. Gredat, F. Valade +11
In the temperature-concentration phase diagram of most iron-based superconductors, antiferromagnetic order is gradually suppressed to zero at a critical point, and a dome of superc…
Dual gate black phosphorus velocity modulated transistor
V. Tayari, N. Hemsworth, O. Cyr-Choinière +3
The layered semiconductor black phosphorus has attracted attention as a 2D atomic crystal that can be prepared in ultra-thin layers for operation as field effect transistors. Despi…
Onset field for Fermi-surface reconstruction in the cuprate superconductor YBCO
G. Grissonnanche, F. Laliberte, S. Dufour-Beausejour +17
Quantum oscillations and negative Hall and Seebeck coefficients at low temperature and high magnetic field have shown the Fermi surface of underdoped cuprates to contain a small cl…
Two types of nematicity in the phase diagram of the cuprate superconductor YBaCuO
O. Cyr-Choinière, G. Grissonnanche, S. Badoux +6
Nematicity has emerged as a key feature of cuprate superconductors, but its link to other fundamental properties such as superconductivity, charge order and the pseudogap remains u…

G. Grissonnanche, F. Laliberte, S. Dufour-Beausejour +16
The recent detection of charge-density modulations in YBa2Cu3Oy and other cuprate superconductors raises new questions about the normal state of underdoped cuprates. In one class o…
Sensitivity of to pressure and magnetic field in the cuprate superconductor YBaCuO: evidence of charge order suppression by pressure
O. Cyr-Choinière, D. LeBoeuf, S. Badoux +7
Cuprate superconductors have a universal tendency to form charge density-wave (CDW) order which competes with superconductivity and is strongest at a doping . Here w…

G. Grissonnanche, O. Cyr-Choiniere, F. Laliberte +20
The upper critical field Hc2 is a fundamental measure of the pairing strength, yet there is no agreement on its magnitude and doping dependence in cuprate superconductors. We have…

Charge density-wave order has been observed in cuprate superconductors whose crystal structure breaks the square symmetry of the CuO2 planes, such as orthorhombic YBa2Cu3Oy (YBCO),…
Decrease of upper critical field with underdoping in cuprate superconductors
J. Chang, N. Doiron-Leyraud, O. Cyr-Choinière +8
The transition temperature Tc of cuprate superconductors falls when the doping p is reduced below a certain optimal value. It is unclear whether this fall is due to strong phase fl…
