Rectified voltage induced by a microwave field in a confined two-dimensional electron gas with a mesoscopic static vortex
David Schmeltzer, Hsuanyeh Chang
We investigate the effect of a microwave field on a confined two dimensional electron gas which contains an insulating region comparable to the Fermi wavelength. The insulating reg…
Persistent Current in Two Coupled Rings
D. Schmeltzer, Hsuan-Yeh Chang
We report the solution of the persistent current in two coupled rings in the presence of external magnetic fluxes. We showed that the magnetic fluxes modify the global phase of the…

We investigate the effect of a microwave field on a confined two dimensional electron gas which contains an insulating region comparable to the Fermi wavelength. The insulating reg…
Transport in a spin polarized Luttinger liquid in the presence of a single impurity
Hsuan-Yeh Chang, D. Schmeltzer
The conductance for a single impurity in a one dimensional gas with electron-electron interaction and Zeeman splitting is considered. We f…
