Quantum Delocalization of the Electric Charge

Bistability in the Electric Current through a Quantum-Dot Capacitively Coupled to a Charge-Qubit

We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...

Differential charge sensing and charge delocalization in a tunable double quantum dot.

We report measurements of a tunable double quantum dot, operating in the quantum regime, with integrated local charge sensors. The spatial resolution of the sensors allows the charge distribution within the double dot system to be resolved at fixed total charge. We use this readout scheme to investigate charge delocalization as a function of temperature and strength of tunnel coupling, demonstr...

Delocalization of the axial charge in the chiral limit

The nucleon's axial vector charge, g A , becomes delocalized in the chiral limit. When m π = 0, and SU (2) L ×SU (2) R is exact, 1/3 of the nucleon's axial charge is to be found at infinite distance from the nucleon. For finite m π this result is approached smoothly as m π → 0. We illustrate this effect by considering the lepton-proton spin-spin interaction arising from Z 0 exchange as a functi...
