The work is focused on the investigation of features of quantum dynamics for photons in spaser systems consisting of metal nanoparticles (NP) and semiconductor quantum dots (QDs). The non-classical photon states generation in a three-particle spaser system with nonlinear plasmon-exciton interaction is predicted.

The Magnetic Field

We consider the thermoelectric response of chaotic or disordered quantum dots in the limit of phase-coherent transport, statistically described by random matrix theory. We calculate the full distribution of the thermoelectric coefficients (Seebeck S and Peltier \PiΠ), and the thermoelectric figure of merit ZT, for large open dots at arbitrary temperature and external magnetic field, when the number of modes in the left and right leads (N_{\rm L} and N_{\rm R}) are large. Our results show that the thermoelectric coefficients and ZT are maximal when the temperature is half the Thouless energy, and the magnetic field is negligible. They remain small, even at their maximum, but they exhibit a type of universality at all temperatures, in which they do not depend on the asymmetry between the left and right leads (N_{\rm L}-N_{\rm R}), even though they depend on (N_{\rm L}+N_{\rm R}).

The evolutions of the von Neumann entropies of the low-lying states in two vertically coupled identical single-electron quantum dot systems with increasing magnetic field and inter-dot separation have been investigated. We show that both the external magnetic field and the inter-dot separation can induce the transition of the entropy of the system. Additionally, a suspicion (that is, the higher the excitation, the larger entropy) has been clarified and proven to be incorrect.
