The present paper theoretically investigates features of quantum dynamics for localized plasmons in three-particle or four-particle spaser systems consisting of metal nanoparticles and semiconductor quantum dots. In the framework of the mean field approximation, the conditions for the observation of stable stationary regimes for single-particle plasmons in spaser systems are revealed, and realization of these regimes is discussed. The strong dipole-dipole interaction between adjacent nanoparticles for the four-particle spaser system is investigated. We show that this interaction can lead to the decreasing of the autocorrelation function values for plasmons. The generation of entangled plasmons in a three-particle spaser system with nonlinear plasmon-exciton interaction is predicted. For the first time the use of an external magnetic field is proposed for control of the cross-correlation between plasmons in the three-particle spaser system.

“…This study aims to investigate the non-classical and non-Gaussian characteristics of photons that have been introduced to a multi-mode (GHZ) entangled coherent state. The purpose is to distil the better one for quantum information processing implementation and compare it to a single-mode excited GHZ-type entangled coherent state [44], measuring quantum correlations in non-classical multipartite coherent states [42,[44][45][46]. In this paper, we propose A class of three-mode excited GHZ-type entangled coherent states (EGHZECSs) that are produced by conducting creation operator operations on GHZ-type ECSs and then decomposing them into the additional photon even (odd) coherent state.…”

In this paper, We investigate three-mode photon-added Greenberger-Horne-Zeilinger (GHZ) entangled coherent states by repeatedly operating the photon-added operator on the GHZ entangled coherent states. The product of two Laguerre polynomials is demonstrated to be connected to the normalizing constant. The influence of the operation on the non-classical and non-Gaussian behavior of the GHZ entangled coherent states is investigated. Sub-Poissonian statistics, such as Mandel's parameter and the negativity of the Wigner function, show that non-classical properties can enhance GHZ entangled coherent states. Finally, the occurrence of the anti-bunching phenomena in this class of tripartite excited states is studied using the second-order correlation function.
