Speeding up a single-molecule DNA motor with a simple catalyst
Yufang Wang, Y. Zhang, N. P. Ong
We demonstrate a catalytic control method for speeding up the single-molecule DNA motor introduced by Li and Tan [Nano Lett. {\bf 2}, 315 (2002)]. A key rate-limiting barrier in th…
Determining the Wiedemann-Franz ratio from the thermal Hall conductivity: Application to Cu and YBa_2Cu_3O_6.95
Y. Zhang, N. P. Ong, Z. A. Xu +2
The Wiedemann-Franz (WF) ratio compares the thermal and electrical conductivities in a metal. We describe a new way to determine its value, based on the thermal Hall conductivity.…
Thermal Conductivity as a Probe of Quasi-Particles in the Cuprates
N. P. Ong, K. Krishana, Y. Zhang +1
In underdoped YBa_2Cu_3O_x (x=6.63), the low-T thermal conductivity Kappa_xx varies steeply with field B at small B, and saturates to a nearly field-independent value at high field…
Effect of the pseudogap on the Hall conductivity in underdoped YBa_2Cu_3O_6+x
Z. A. Xu, Y. Zhang, N. P. Ong
In underdoped YBa_2Cu_3O_x (YBCO) with x = 6.63, the opening of the pseudogap at T^* ~ 160 K has a strong effect on the Hall angle tan(theta). While the Hall response is significan…
