• Abstract summary: We show how radiative processes of the two-atom entangled state can be manipulated by the atomic configuration undergoing noninertial motion. We evaluate the resonance energy shift and the relaxation rate of energy of the two atom system from the self-reaction contribution in the Heisenberg equation of motion.

• Abstract: We study the resonance interaction between two entangled identical atoms coupled to a quantized scalar field vacuum, and accelerating between two mirrors. We show how radiative processes of the two-atom entangled state can be manipulated by the atomic configuration undergoing noninertial motion. Incorporating the Heisenberg picture with symmetric operator ordering, the vacuum fluctuation and the self-reaction contributions are distinguished. We evaluate the resonance energy shift and the relaxation rate of energy of the two atom system from the self-reaction contribution in the Heisenberg equation of motion. We investigate the variation of these two quantities with relevant parameters such as atomic acceleration, interatomic distance and position with respect to the boundaries. We show that both the energy level shift and the relaxation rate can be controlled by tuning the above parameters.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

  We investigate the dynamics of a two-level atom flying through a photonic cavity when the light-matter interaction is in the ultrastrong coupling regime. We adopt a closed full quantum description that takes into account the quantization of the atom center-of-mass motion. In the first case, the atom experiences a emphquantum regenerative braking mechanism, based on temporary storage of energy into virtual excitations.

  We study a system of two interacting, non-indentical quantum emitters driven by a coherent field. We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters. This can be exploited for applications such as superresolution imaging of point-like sources.

  We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state. Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system. We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.

• Radiation-reaction-induced transitions of two maximally entangled atoms in non-inertial motion [0.0]
  We study the average rate of change of energy of two identical two-level atoms interacting with the vacuum massless scalar field in synchronized motion. We first show that for the two-atom system initially prepared in the factorizable eigenstates $|g_Ag_Brangle$ and $|e_Ae_Brangle$, both vacuum fluctuations and atomic radiation reaction contribute to the average rate of change of energy of the two-atom system. We then consider two special cases of motion of the two-atom system which is initially prepared in the symmetric/antisymmetric entangled state
