Tunneling into a two-dimensional electron system in a strong magnetic field
Tunneling into a two-dimensional electron system in a strong magnetic field
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-size diagonalization, we find that its spectral weight is suppressed near zero energy, reaches a maximum at an energy of …
