“…Many alkali atoms, e.g., Rydberg Rubidium atom, have been also experimentally used (Petrosyan et al 2011; Wang et al 2004). Properties of the electromagnetic fields interacting with a three-level Λ-type atom were studied in the semi-classical (Kocharovskaya and Khanin 1988; Harris et al 1990; Harris 1997; Scully and Zubairy 1997; Dantan et al 2012) and full-quantum (Wang et al 1992; Akamatsu et al 2004; Johnsson and Fleischhauer 2002) models by a weak field approximation (WFA) method. In WFA the possibility of research on the small intensity of coupling field disappears because the coupling field should have larger intensity compare to the probe field to establish approximation.…”

Recently, the master equations for the interaction of two-mode photons with a three-level Λ-type atom are exactly solved for the coherence terms. In this paper the exact absorption spectrum is applied for the presentation of a non-demolition photon counting method, for a few number of coupling photons, and its benefits are discussed. The exact scheme is also applied where the coupling photons are squeezed and the photon counting method is also developed for the measurement of the squeezing parameter of the coupling photons.

“…The study of optical bistability and multistability in optical nonlinear systems has been a subject of interest over the last two decades. In the past, most of the optical systems concerned were based on the light-matter interaction and involved using the two-level atomic model or other atomic models which possess saturated absorptive characteristics [1][2][3][4][5][6][7][8][9][10][11]. In recent years, a new kind of optical bistability-increasing absorption optical bistability (IAOB)-has aroused great interest in scientists [12][13][14][15].…”

This paper presents an approach to the intracavity interaction of electromagnetic waves with anharmonic lattice vibrations of ionic crystals. The nonlinear lattice dynamics and an expression for the nonlinear polarization are derived in terms of optical phonon modes. In the rotating-wave approximation the total coherent Hamiltonian of the system is derived. Using the corresponding equation of steady states, the increasing absorption optical bistability (IAOB), as a nonlinear effect, is demonstrated. The results show that optical nonlinearities due to the interaction of photons with various elementary excitations of bosonic type such as phonons and excitons may be the origin of IAOB, which is consistent with our previous works.

“…A existência de mais de um atrator para um conjunto de parâmetros tem sido alvo de diversos estudos [22]. Essa coexistência de atratores, também chamada de multiestabilidade,é encontrada em diversasáreas de aplicação de sistemas dinâmicos [23][24][25][26][27][28][29]. Esses sistemas multiestáveis apresentam alguns fenômenos interessantes, quando submetidos a uma perturbação [30,31] [34,37].…”
