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…

Non-local electrodynamics in ultra-pure PdCoO

Graham Baker, Timothy W. Branch, J. S. Bobowski +11

The motion of electrons in the vast majority of conductors is diffusive, obeying Ohm's law. However, the recent discovery and growth of high-purity materials with extremely long el…

Magnetization of underdoped YBaCuO above the irreversibility field

Jing Fei Yu, B. J. Ramshaw, I. Kokanović +9

Torque magnetization measurements on YBaCuO (YBCO) at doping (), in DC fields () up to 33 T and temperatures down to 4.5 K, show that weak diamagne…

Quasiparticle mass enhancement approaching optimal doping in a high-Tc superconductor

B. J. Ramshaw, S. E. Sebastian, R. D. McDonald +8

In the quest for superconductors with high transition temperatures (Ts), one emerging motif is that unconventional superconductivity is enhanced by fluctuations of a b…

Vortex Lattice Melting and Hc2 in underdoped YBa2Cu3Oy

B. J. Ramshaw, James Day, Baptiste Vignolle +7

Vortices in a type-II superconductor form a lattice structure that melts when the thermal displacement of the vortices is an appreciable fraction of the distance between vortices.…

Coherent c-axis transport in the underdoped cuprate superconductor YBCO

B. Vignolle, B. J. Ramshaw, James Day +7

The electrical resistivity rho_c of the underdoped cuprate superconductor YBCO was measured perpendicular to the CuO_2 planes on ultra-high quality single crystals in magnetic fiel…
