“…The interaction in COM systems * Author to whom any correspondence should be addressed. has been extended in many aspects, such as the preparation of optomechanical entanglement [1,2], the generation of mechanical squeezing [3][4][5], ground-state cooling [6,7], thermophonon transport [8], optical sensors [9] and quantum nondemolition measurement [10]. Optomechanically induced transparency (OMIT), as a prominent example closely relevant to COM, is analogous to atomic electromagnetically induced transparency (EIT) [11,12].…”

We investigate tunable double optomechanically induced transparency and slow/fast phenomena in a hybrid electro-optomechanical system. The hybrid system consists of an optical cavity with an optical parametric amplifier (OPA) and two charged mechanical resonators. The double optomechanical induce transparency can be exhibited by manipulating the coupling parameters of the electro-optomechanical system. Specifically, the number of transparent points and the width of transparent windows increase with an increase in the coupling constant. Furthermore, the phenomenon of double transparency is strongly influenced by the parametric gain of OPA and by the Coulomb interaction between the two mechanical oscillators. It is found that the larger parametric gain and Coulomb coupling induce an increasing width of transparency windows. Moreover, we study the slow/fast light effect associated with the rapid phase change of the transmission of probe field. Our approach provides a great flexibility for controlling double induced transparency, and has potential applications in optical information storage and optical communication.

“…[10,11] In particular, it allows the exploration of quantum effects in macroscopic objects by creating quantum states of mechanical motion, such as squeezed states [12][13][14] or entangled states. [15][16][17] These states can exhibit behaviors that are distinctly different from classical mechanical systems. [18] Moreover, cavity optomechanics enables the study of fundamental physics phenomena, including quantum measurement and decoherence processes.…”

This study investigates the theoretical aspects of the interaction between photons with mass and a mechanical oscillator as drawn within the framework of cavity optomechanics. The study employs Proca theory as the mathematical framework to initially describe the dynamics of massive photons in a Fabry‐Perot cavity with a movable mass, both in classical and quantum scenarios. It quantifies the modifications induced by the nonzero photon mass, considering first‐ and second‐order effects, and derives expressions for the amplification of radiation pressure resulting from the presence of nonzero photon mass. Additionally, it derives the Hamiltonian of the quantum optomechanical system, incorporating the effects of photon mass at first and second order. It anticipates that experimental realization of massive optomechanics can be achieved by utilizing Proca material, which is a spatio‐temporally dispersive material that exhibits behavior equivalent to Proca theory in a vacuum, thus enabling the study of the interaction between massive photons and mechanical systems in cavity‐based optomechanical setups (referred to as massive cavity optomechanics). The study presented here caters to a diverse audience with an interest in the analysis and measurement of interactions among massive objects at the quantum scale.

“…While the anharmonic interaction is essential for the realization of non-Gaussian states, its flip side is that it results in the evolution towards quantum states with correlations between the optical and mechanical degrees of freedom. The preparation of a pure state of one of the subsystems can be achieved in terms of a projective measurement on the other subsystem [2,3,28]. Such a scheme, however, is intrinsically probabilistic with a success probability limited by the multitude of possible measurement outcomes.…”

Cavity-optomechanics is an ideal platform for the generation non-Gaussian quantum states due to the anharmonic interaction between the light field and the mechanical oscillator; but exactly this interaction also impedes the preparation in pure states of the light field. In this paper we derive a driving protocol that helps to exploit the anharmonic interaction for state preparation, and that ensures that the state of the light field remains close-to-pure. This shall enable the deterministic preparation of photon Fock states or coherent superpositions thereof.
