Axisymmetric plasma mode in disk with two-dimensional electron gas

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 ,...

Two dimensional electron gas at oxide interfaces

Observation of an interedge magnetoplasmon mode in a degenerate two-dimensional electron gas.

We study the propagation of edge magnetoplasmons by time-resolved current measurements in a sample which allows for selective detection of edge states in the quantum Hall regime. At filling factors close to nu=3 we observe two decoupled modes of edge excitations, one of which is related to the innermost compressible strip and is identified as an interedge magnetoplasmon mode. From the analysis ...

Physics. Cooking a two-dimensional electron gas with microwaves.

O ne would think that a mouse lacking the major excitatory neurotransmit-ter in the brain would be a dead mouse, and indeed it is—but it's not nearly as dead as one might have thought. Two groups have knocked out the gene for the main vesicular glutamate transporter, VGLUT1, and surprisingly, these mice live for several months. The studies by Fremeau et al. (1) on page 1815 in this issue and by...

Magnetic reconnection in a magnetosphere-accretion-disk system Axisymmetric stationary states and two-dimensional reconnection simulations

In the present paper we investigate the transport of accreting plasma across the magnetopause onto a strongly magnetized massive star (i.e. white dwarf or neutron star) by magnetic reconnection. A simplified axisymmetric magnetic field model of an aligned rotator is used to study the reconnection process. To be able to separate effects caused by instabilities of the system from intrinsic time-d...
