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…

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.
