In this paper, the quantum properties of a two-level atom and the cavity-ﬁeld in the Jaynes–Cummings model with the gravity beyond the rotating wave approximation are investigated. For this purpose, by solving the Schrödinger equation in the interaction picture, the evolving state of the system is found by which the inﬂuence of the counter-rotating terms on the dynamical behaviour of atomic population inversion and the probability distribution of the cavity-ﬁeld as quantum properties is explored. The results in the atom–ﬁeld system beyond the rotating wave approximation with the gravity show that the quantum properties are not completely suppressed under certain conditions.
