For future experiments in cavity QED with self-assembled quantum dots, the GaAs/AlGaAs system is the most appropriate choice of material, due to the relative maturity of the growth of InAs/InGaAs quantum dots [138, 139, 140] within this system. As the refractive index of GaAs and its alloys is relatively close to that of Si (n GaAs ∼ 3.5 and n AlAs ∼ 2.9 at λ ∼ 1.25 µm), the PC cavity design of...

The process of photon splitting, becomes allowed in the presence of strong magnetic field. We calculate the influence of magnetized plasma on the photon splitting absorption coefficient. We calculate the refraction coefficients and polarization vectors with the inclusion of the vacuum terms at an arbitrary value of the magnetic field, and then find photon splitting matrix element taking into ac...

Comparison of the theory of Rabi oscillations with experiment [M. Wilczewski and M. Czachor, Phys. Rev. A 79, 033836 (2009)] suggests that cavity lifetime parameters obtained in measurements with many photons may be much smaller than those applicable to almost vacuum states of light. In this context, we show that the conclusion remains unchanged even if one takes a more realistic description of...

Blue-detuned dipole traps and their ability to preserve atomic coherences are interesting for precision measurement applications. In this paper, we present experimental studies on the differential ac Stark shift of the ground-state hyperfine splitting in 87Rb atoms confined in a dynamic blue-detuned dipole trap. We systematically study the power and detuning effects on the Rabi resonance freque...

We show that Rabi oscillations of a degenerate fermionic or bosonic gas trapped in a double-well potential can be exploited for the interferometric measurement of external forces at micrometer length scales. The Rabi interferometer is less sensitive, but easier to implement, than the MachZehnder since it does not require dynamical beam-splitting/recombination processes. As an application we pro...

We have experimentally observed the evolution of the vacuum Rabi doublet into a singlet in the transmission spectrum of a cavity filled with a collection of two-level atoms. For very weak excitation the peaks behave like simple harmonic oscillators, but become anharmonic as the excitation increases. The anharmonicity grows to a point where hysteresis appears in the transmission spectrum, eventu...

We experimentally study a circuit quantum acoustodynamics system, which consists of superconducting artificial atom, coupled to both two-dimensional surface acoustic wave resonator and one-dimensional microwave transmission line. The strong coupling between the atom is confirmed by observation vacuum Rabi splitting at base temperature dilution refrigerator. show that propagation photons in line...
