We consider the effect of electron correlations on tunneling from a 2D electron layer in a magnetic field parallel to the layer. A tunneling electron can exchange its momentum with other electrons, which leads to an exponential increase of the tunneling rate compared to the single-electron approximation. The effect depends on the interrelation between the… (More)

A physically different problem of tunneling between lattice sites of the WCs at the edges of a quantum Hall system was discussed by M . B . Hastings and L . S . Levitov [
