Nernst effect and anomalous transport in cuprates: A preformed-pair alternative to the vortex scenario
Nernst effect and anomalous transport in cuprates: A preformed-pair alternative to the vortex scenario
We address those puzzling experiments in underdoped high $T_c$ superconductors which have been associated with normal state "vortices" and show these data can be understood as deriving from preformed pairs with onset temperature $T^* > T_c$. For uncorrelated bosons in small magnetic fields, and arbitrary $T^*/T_c$, we present the exact …
