Thermal Hall conductivity in the strongest cuprate superconductor: Estimate of the mean free path in the trilayer cuprate HgBaCaCuO
Munkhtuguldur Altangerel, Quentin Barthélemy, Étienne Lefrançois +12
The thermal Hall conductivity of the trilayer cuprate HgBaCaCuO (Hg1223) - the superconductor with the highest critical temperature at ambient pressure -…
Signatures of two gaps in the spin susceptibility of a cuprate superconductor
R. Zhou, I. Vinograd, M. Hirata +10
A major obstacle to understanding high-Tc cuprates is that superconductivity precludes observing normal-state properties at low temperatures. One prime example is the normal-state…
NMR study of charge density waves under hydrostatic pressure in YBa2Cu3Oy
I. Vinograd, R. Zhou, H. Mayaffre +5
The effect of hydrostatic pressure (P) on charge density waves (CDW) in YBa2Cu3Oy has recently been controversial. Using NMR, we find that both the short-range CDW in the normal st…
Orbital Symmetries of Charge Density Wave Order in YBa2Cu3O6+x
Christopher McMahon, A. J. Achkar, E. H. da Silva Neto +10
Charge density wave (CDW) order has been shown to compete and coexist with superconductivity in underdoped cuprates. Theoretical proposals for the CDW order include an unconvention…
Reply to "Comment on `No evidence for orbital loop currents in charge-ordered YBaCuO from polarized neutron diffraction' "
T. P. Croft, E. Blackburn, J. Kulda +4
The issues raised in the preceding comment of Bourges et al. [arXiv:1710.08173, Phys. Rev. B 98, 016501 (2018)] are shown to be unfounded. We highlight the complications caused by…
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 =…
Investigation of potential fluctuating intra-unit cell magnetic order in cuprates by muon spin relaxation
A. Pal, K. Akintola, M. Potma +6
We report low temperature muon spin relaxation (muSR) measurements of the high-transition-temperature (Tc) cuprate superconductors Bi{2+x}Sr{2-x}CaCu2O{8+δ} and YBa2Cu3O6.57, aimed…
Change of carrier density at the pseudogap critical point of a cuprate superconductor
S. Badoux, W. Tabis, F. Laliberté +10
The pseudogap is a central puzzle of cuprate superconductors. Its connection to the Mott insulator at low doping remains ambiguous and its relation to the charge order that rec…
Thermodynamic phase diagram of static charge order in underdoped YBCO
David LeBoeuf, S. Krämer, W. N. Hardy +3
The interplay between superconductivity and any other competing order is an essential part of the long-standing debate on the origin of high temperature superconductivity in cuprat…
Lifshitz critical point in the cuprate superconductor YBa2Cu3Oy from high-field Hall effect measurements
David LeBoeuf, Nicolas Doiron-Leyraud, B. Vignolle +14
The Hall coefficient R_H of the cuprate superconductor YBa2Cu3Oy was measured in magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152, in the underdoped regime…
Broken rotational symmetry in the pseudogap phase of a high-Tc superconductor
R. Daou, J. Chang, David LeBoeuf +8
The nature of the pseudogap phase is a central problem in the quest to understand high-Tc cuprate superconductors. A fundamental question is what symmetries are broken when that ph…
