We investigate the properties of the one-electron Green's function in an interacting two-dimensional electron system in a strong magnetic field, which describes an electron tunneling into such a system. From finite-sise diagonalisation, we find that its spectral weight is suppressed near sero energy, reaches a minimum at an energy of about 0.2e 2 /el c , and decays exponentially at higher energies. We propose a theoretical model to account for the low-energy behavior. For the case of Coulomb… 
Tunneling spectroscopy of disordered two-dimensional electron gas in the quantum Hall regime
Recently, Dial et al. presented measurements of the tunneling density of states into the bulk of a two dimensional electron gas under strong magnetic fields. Several high energy features appear in
Tunneling between two-dimensional electron systems in a high magnetic field : Role of interlayer interactions
Author(s): Klironomos, Filippos | Abstract: We calculate the tunneling current for a bilayer quantum Hall system in the interlayer incoherent regime. In order to capture the strong correlation
Reconstructing the electron in a fractionalized quantum fluid.
It is shown that a long-lived electronlike quasiparticle also exists in the excitation spectrum: the state obtained by the application of an electron creation operator to a fractional quantum Hall ground state has a nonzero overlap with a complex, high energy bound state containing an odd number of composite-fermion quasIParticles.
Dynamics of the two-dimensional electron gas in the lowest Landau level : a continuum elasticity approach
We develop a bosonization scheme for the collective dynamics of a spinless two-dimensional electron gas (2DEG) in the lowest Landau level. The system is treated as a continuous elastic medium, and
Suppression of the equilibrium tunneling current between slightly disordered two-dimensional electron systems with different electron concentrations in a high magnetic field
Tunneling between parallel two-dimensional electron gases (2DEG) in accumulation layers formed on both sides of the single doped AlGaAs barrier are examined in both zero and high magnetic field.
