Vacuum-dressed cavity magnetotransport of a two-dimensional electron gas

Magnetotransport in a two-dimensional electron gas at large filling factors

We derive the quantum Boltzmann equation for the two-dimensional electron gas in a magnetic field such that the filling factor n@1. This equation describes all of the effects of the external fields on the impurity collision integral including Shubnikov–de Haas oscillations, the smooth part of the magnetoresistance, and nonlinear transport. Furthermore, we obtain quantitative results for the eff...

Magnetotransport in a chaotic scattering cavity with tunable electron density

We have measured the resistance versus magnetic field and Fermi energy for two stadium-shaped cavities in which chaotic scattering is expected. We fit the power spectra of the magnetoresistance fluctuations to semiclassical chaotic scattering theory and find a characteristic field which scales with cavity dimensions as predicted by classical simulations. Measurements of conductance versus Fermi...

Two-dimensional electron gas near full polarization

We establish the consistency of the Fermi liquid description and find a relation between the Fermi liquid constants for a two-dimensional electron system near the point of full polarization due to a parallel magnetic field H. Our results enable us to predict connections between different thermodynamic properties of the system. In particular, we find that near the point of full polarization Hc ,...
