Wiedemann-Franz law in the underdoped cuprate superconductor YBa 2 Cu 3 O y

The authors measured the electrical and thermal Hall conductivities of YBa${}_{2}$Cu${}_{3}$O${}_{y}$ in high magnetic fields to investigate the nature of the nonsuperconducting ground state in underdoped cuprates. They found that the Wiedemann-Franz law is obeyed in the $T$=0 limit as soon as the vortex solid melts at high field. This shows that there is no vortex liquid at $T$=0 and it imposes a clear constraint on the nature of excitations in the enigmatic pseudogap phase of cuprate superconductors.
