“…where r = r/κ is the dimensionless control field amplitude. At large enough NEC parameter C Γ 1, coefficient A in ( 47) is essentially positive, and we can obtain significant amplification of macroscopic field within the network structure that is proportional to C Γ κD 0 /2 ∝ k N. In this limit, for the laser average photon number from (45) and (52), we obtain…”

“…It can be assumed that photons scatter along the paths that form random graphs. Recently, in [52], we offered a 2D material for the random laser that exhibits randomly formed networks with nodes that contain two-level systems (atoms, quantum dots, etc.). The network edges represent channels (waveguides) that provide coupling between the nodes.…”

In this work, we suggest a quantum-like simulator concept to study social processes related to the solution of NP-hard problems. The simulator is based on the solaser model recently proposed by us in the framework of information cascade growth and echo chamber formation in social network communities. The simulator is connected with the random laser approach that we examine in the A and D-class (superradiant) laser limits. Novel network-enforced cooperativity parameters of decision-making agents, which may be measured as a result of the solaser simulation, are introduced and justified for social systems. The innovation diffusion in complex networks is discussed as one of the possible impacts of our proposal.

A new mechanism of the generation of a random laser based on a random photonic network with dissipative tunneling of photons between microcavities that are placed at the nodes of such network and contain identical two-level quantum systems has been revealed. It has been shown that an additional source of photon losses in tunneling promotes the separation of individual modes of the random laser and the achievement of the lasing threshold even at a vanishingly small population inversion. In this case, the enhancement of laser modes has an interference nature and is due to the energy redistribution between the nodes of the photonic network that correspond to different signs of the frequency detuning of stationary modes of the random laser from the transition frequency of two-level systems. It has been shown that the traditional lasing mechanism, which demonstrates features of the spectrum of single microcavities, i.e., is almost independent of the topological properties of the network and the tunneling parameter, is present in the region of zero detuning.
