“…This ideal system has been studied with non-linear rate equations [15,[20][21][22][23][24], with a Fokker-Planck equation [25] as well as with a reduced density matrix equation (RDM) [17,26]. In most studies, the quantum emitters are treated as two-level systems incoherently driven by an effective pump.…”

We calculate the quantum state of the plasmon field excited by an ensemble of molecular emitters, which are driven by exchange of electrons with metallic nano-particle electrodes. Assuming identical emitters that are coupled collectively to the plasmon mode but are otherwise subject to independent relaxation channels, we show that symmetry constraints on the total system density matrix imply a drastic reduction in the numerical complexity. For N m three-level molecules we may thus represent the density matrix by a number of terms scaling as (N m + 8)!/(8!N m !) instead of 9 N m , and this allows exact simulations of up to N m = 10 molecules. Our simulations demonstrate that many emitters compensate strong plasmon damping and lead to the population of high plasmon number states and a narrowed linewidth of the plasmon field. For large N m , our exact results are reproduced by an approximate approach based on the plasmon reduced density matrix. With this approach, we have extended the simulations to more than 50 molecules and shown that the plasmon number state population follows a Poisson-like distribution. An alternative approach based on nonlinear rate equations for the molecular state populations and the mean plasmon number also reproduce the main lasing characteristics of the system.

We show that net amplification of surface plasmons is achieved in channel in a metal plate due to nonradiative excitation by quantum dots. This makes possible lossless plasmon transmission lines in the channel as well as the amplification and generation of coherent surface plasmons. As an example, a ring channel spaser is considered. In this regard, studies of plasmons propagating along 1D objects such as wires [3], wedges [4,5], and channels [6,7] are of great interest.Losses in metals are the main obstacle to practical applications of plasmonics. It has been suggested that this problem can be overcome by compensating loss in a gain medium [8][9][10][11].This relates nanoplasmonics to quantum optics [1,2]. In particular, a generator of plasmons propagating along a flat surface has been suggested in Refs. [12][13][14]. In this system, periodic surface corrugations produce Bragg mirrors of the resonator cavity. The first quantum nanoplasmonic device which was referred to as spaser (Surface Plasmon Amplification by Stimulated Emission of Radiation) was proposed in Ref. [1]. The spaser consists of a quantum dot (QD) located near a metal nanoparticle (NP). The plasmonic oscillations in the NP play the
