Interference effects in nanostructures II

Thomas Ihn

Beyond the basic interference effects introduced in Chapter 14, further interesting interference phenomena exist in semiconductor nanostructures, the discussion of which requires more prior knowledge. This chapter discusses the Fano effect in nanostructure transport that has been found in a number of very different experiments. Furthermore, it discusses experiments that measure the transmission phase in addition to the transmission probability using interferometric arrangements. Finally, the chapter returns to the topic of decoherence, and introduces experiments aiming at controlled decoherence of quantum states. This topic requires knowledge of interference and the basics of decoherence, and incorporates ideas of shot noise, the Aharonov–Bohm effect, the quantum Hall effect, double quantum dot physics, and the theory of quantum measurement.

The squeezing spectrum of a quantum emitter coupled to an optical nanostructure

D. Cano, Harald R. Haakh, Mario Agio

We analyze the spectral properties of the reduced quantum fluctuations arising from a single two-level emitter coupled to an optical nanostructure. A closed expression for the squeezing spectrum in this hybrid system is presented that includes the effect of additional phase decoherence. We consider a metallic nanoantenna to illustrate how the hybrid system can increase the bandwidth and overcome the limits to the generation of such spectral squeezing in terms of driving field intensity and the effect of pure dephasing.
