Tunneling into a Two-Dimensional Electron Liquid in a Weak Magnetic Field.

We study the spectral density function of a two-dimensional electron liquid in a weak magnetic field, the filling factor ν ≫ 1. A hydrodynamic model for low-energy excitations of the liquid is developed. It is found that even at ν ≫ 1 the density of states exhibits a gap at low energies. Its width 2E 0 depends on the strength of interaction only logarithmically, 2E 0 = (¯ hω c /ν) ln(νe 2 /ε¯ h...

Ground state of a two-dimensional electron liquid in a weak magnetic field.

We consider a clean two-dimensional electron liquid in a weak magnetic field where N@1 lower Landau levels are completely filled, while the upper level is only partially filled. Due to a screening by the lower Landau levels, the repulsive interaction between any two electrons at the upper level as a function of the separation between the guiding centers of their cyclotron orbits abruptly drops ...

Charge density wave in two-dimensional electron liquid in weak magnetic field.

We study the ground state of a clean two-dimensional electron liquid in a weak magnetic field where N ¿ 1 lower Landau levels are completely filled and the upper level is partially filled. It is shown that the electrons at the upper Landau level form domains with filling factors equal to 1 and zero. The domains alternate with a spatial period of order of the cyclotron radius, which is much larg...

Novel edge excitations of two-dimensional electron liquid in a magnetic field.

We investigate the low-energy spectrum of excitations of a compressible electron liquid in a strong magnetic field. These excitations are localized at the periphery of the system. The analysis of a realistic model of a smooth edge yields new branches of acoustic excitation spectrum in addition to the well known edge magnetoplasmon mode. The velocities are found and the observability conditions ...

Electron band structure in a two-dimensional periodic magnetic field.

In this paper we study the energy spectrum of a two dimensional electron gas (2DEG) in a two dimensional periodic magnetic field. Both a square magnetic lattice and a triangular one are considered. We consider the general case where the magnetic field in a cell can be of any shape. A general feature of the band structure is bandwidth oscillation as a function of the Landau index. A triangular m...
