Excitonic Fock-Darwin Spectra in Quantum Dots

Applying a magnetic field on an electronic system where levels are quantized has the effect of lifting angular momentum state degeneracies. If one has access to magnetic fields such that the cyclotron energy beomes comparable to or greater that the inter-level separation in the system, a criss-cross pattern of energy levels in the Energy vs Magnetic field diagram may be observed. For specific magnetic fields, positive angular momentum states of lower levels can become degenerate with negative angular momentum states of higher levels, thus prompting one to expect interesting physical phenomena related to mixing of states.NRC publication: Ye
