Two point-contact interferometer for quantum Hall systems
C. de C. Chamon, D. E. Freed, S. A. Kivelson +2
We propose a device, consisting of a Hall bar with two weak barriers, that can be used to study quantum interference effects in a strongly correlated system. We show how the device…

Symmetries of the Dissipative Hofstadter Model
Denise E. Freed
The dissipative Hofstadter model, which describes a particle in 2-D subject to a periodic potential, uniform magnetic field, and dissipation, is also related to open string boundar…
