Original Source: A Molecular Quantized Charge Pump.
A novel single electron pump based on individual molecules (a single wall carbon nanotube) is discussed in terms of the hybrid superconducting-normal conducting pumping principle. A concept demonstration device has been built based on a carbon nanotube contacted by Nb-Ti leads. Charge current quantization is achieved through rf modulation of the back gate voltage. The device is able to transfer a given number of electrons per pumping cycle. Single electron pumping is achieved for pumping frequencies up to 8...

Quantized four-terminal resistances in a ferromagnetic graphene p-n junction.
The quantum Hall and longitudinal resistances in four-terminal ferromagnetic graphene p-n junctions under a perpendicular magnetic field are investigated. In the Hall measurement, the transverse conta...
Real-time dynamics of quantized vortices in a unitary Fermi superfluid.
We introduce a comprehensive theoretical framework for the fermionic superfluid dynamics, grounded on a local extension of the time-dependent density functional theory. With this approach, we describe...
Experimental observation of the quantum anomalous Hall effect in a magnetic topological insulator.
The quantized version of the anomalous Hall effect has been predicted to occur in magnetic topological insulators, but the experimental realization has been challenging. Here, we report the observatio...
