Fano Resonance of Nanowire Surface Plasmons coupled to Quantum Dots and the Leggett-Garg inequality in Cavity QED with atomic mirrors

Abstract

In this thesis we first study the double quantum dots coupled to the surface plasmons with linear and parabolic dispersion relations Analytical expressions are obtained for the transmission and reflection spectra by solving the corresponding eigenvalue equations We find that the Fano line shape appears in the transmission spectrum and there exists correlation between the two-dot entanglement and the Fano resonance In the second part a method to enhance the cavity QED coupling by using an ensemble of atoms has been discussed By placing these atoms in specified locations one can obtain a strong cavity QED configuration With an impurity atom in the cavity the strong coupling may be reached and the excitation dynamics reveals the Rabi-like oscillations We further examine the quantum coherence of this system by using the Leggett-Garg inequality
