Fractional charge revealed in computer simulations of resonant tunneling in the fractional quantum Hall regime
arXiv:cond-mat/0608252 · doi:10.1103/PhysRevLett.97.076802
Abstract
The concept of fractional charge is central to the theory of the fractional quantum Hall effect (FQHE). Here I use exact diagonalization as well as configuration space renormalization (CSR) to study finite clusters which are large enough to contain two independent edges. I analyze the conditions of resonant tunneling between the two edges. The "computer experiment" reveals a periodic sequence of resonant tunneling events consistent with the experimentally observed fractional quantization of electric charge in units of e/3 and e/5.
