Coulomb blockade in the fractional quantum Hall effect regime
We use chiral Luttinger liquid theory to study transport through a quantum dot in the fractional quantum Hall effect regime and find rich non-Fermi-liquid tunneling characteristics. In particular, we predict a remarkable Coulomb-blockade-type energy gap that is quantized in units of the noninteracting level spacing, powerlaw tunneling exponents for voltages beyond threshold, and a line shape as...
متن کاملCoulomb blockade in Quantum Dots
In the resonant tunnelling diode we have treated electrons as non interacting particles. We have discussed their wave nature, which led to quantized energy states in small and coherent cavities. Qualitatively this is due to the requirement that an integer number of Fermi wavelengths has to fit between the barriers. Here we begin in the opposite limit by neglecting space quantization effects in ...
متن کاملQuantum Effects in Coulomb Blockade
We review the quantum interference effects in a system of interacting electrons confined to a quantum dot. The review starts with a description of an isolated quantum dot. We discuss the Random Matrix theory (RMT) of the one-electron states in the dot, present the universal form of the interaction Hamiltonian compatible with the RMT, and derive the leading corrections to the universal interacti...
متن کاملRobustness of Topological Order in Semiconductor-Superconductor Nanowires in the Coulomb Blockade Regime
Semiconductor-superconductor hybrid systems are promising candidates for the realization Majorana fermions and topological order, i.e. topologically protected degeneracies, in solid state devices. We show that the topological order is mirrored in the excitation spectra and can be observed in nonlinear Coulomb blockade transport through a ring-shaped nanowire. Especially, the excitation spectrum...
