Density of states between Landau levels in a two-dimensional electron gas.

Two-dimensional electron systems (2D ES}in a perpendicular magnetic field B display fascinating quantum oscillations. ' Examples of 2D ES's are electrons confined to interfaces in GaAs-Ga& „Al„As layered heterostructures and electrons at surfaces in Si metal-oxidesemiconductor field-effect transistors (MOSFET's). Earliest interest was in electron transport properties, the integer quantum hall e...

Local Field Correction Effect on Dicluster Stopping Power in a Strongly Coupled Two-Dimensional Electron Gas System

We calculate the stopping power for heavy-ion diclusters moving in a strongly coupled two-dimensional electron gas system by using the local field corrected dielectric function at finite temperature. We obtain a parameterized local field correction factor based on a relation between the thermal compressibility and exchange-correlation energy in two-dimension. The interpolated parameter is deriv...

The Landau–Ginzberg Theory for the Two-Dimensional Bose Gas

Using results from sheaf theory combined with the phenomenological theory of the two-dimensional superfluid, the precipitation of quantum vortices is shown to be the genesis of a macroscopic order parameter for a phase transition in two dimensions.
