“…A rapidly developing field of science, which is known as γ-ray (or hard x-ray) quantum optics based on Mössbauer effect, provides unambiguous test of many concepts and ideas of coherent quantum optics with γ-photons resonantly interacting with ensemble of nuclei. Recent experimental achievements in this domain include electromagnetically induced transparency in a cavity [12], the collective Lamb shift [13], vacuum-assisted generation of atomic coherences [14], single-photon supperradiance in nuclear absorbing multilayer structures [15], slow gamma photon [16], subluminal pulse propagation using nuclear resonances [17], photon shaping [18,19], and γ-echo [20][21][22].…”

We measure subnanometer displacements of thin samples vibrated by piezotransducer. Samples contain 57 Fe nuclei, which are exposed to 14.4 keV γ-radiation. Vibration produces sidebands from a single absorption line of the sample. The sideband intensities depend on the vibration amplitude and its distribution along the sample. We developed a model of this distribution, which adequately describes the spectra of powder and stainless steel (SS) absorbers. We propose to filter γ-radiation through a small round hole in the lead mask, placed before the absorber. In this case only a small spot of the vibrated absorber is observed. We found for SS foil that nuclei, exposed to γ-radiation in this small spot, vibrate with almost the same amplitudes whose difference does not exceed a few picometers within the irradiated area.

Radiation burst from a singleγ-photon field

The radiation burst from a single gamma-photon field interacting with a dense resonant absorber is studied theoretically and experimentally. This effect was discovered for the fist time by P. Helisto et al., Phys. Rev. Lett. 66, 2037Lett. 66, (1991 and it was named "gamma echo". The echo is generated by 180-degree phase shift of the incident radiation field, attained by an abrupt change of the position of the absorber with respect to the radiation source during the coherence time of the photon wave packet. Three distinguishing cases of "gamma echo" are considered, i.e., the photon is in exact resonance with the absorber, close to resonance (on the slope of the absorption line), and far from resonance (on the far wings of the resonance line). In resonance the amplitude of the radiation burst is two times larger than the amplitude of the input radiation field just before its phase shift. This burst was explained by P. Helisto et al. as a result of constructive interference of the coherently scattered field with the phase shifted input field, both having almost the same amplitude. We found that out of resonance the scattered radiation field acquires an additional component with almost the same amplitude as the amplitude of the incident radiation field. The phase of the additional field depends on the optical thickness of the absorber and resonant detuning.Far from resonance this field interferes destructively with the phase-shifted incident radiation field and radiation quenching is observed. Close to resonance three fields interfere constructively and the amplitude of the radiation burst is three times larger than the amplitude of the input radiation field.

“…Alternatively, in the realm of x-ray quantum optics [33][34][35][36][37][38][39][40][41], for instance the 57 Fe Mössbauer transition is characterized by ω 0 /2π ∼ 10 18 Hz, γ 0 ∼ MHz, a ∼ pm, and U = 0. For these systems, crystalline solid state targets naturally provide ordered arrays of x-ray emitters.…”

Probing few-excitation eigenstates of interacting atoms on a lattice by observing their collective light emission in the far field

The collective emission from a one-dimensional chain of interacting two-level atoms coupled to a common electromagnetic reservoir is investigated. We derive the system's dissipative few-excitation eigenstates, and analyze its static properties, including the collective dipole moments and branching ratios between different eigenstates. Next, we study the dynamics, and characterize the light emitted or scattered by such a system via different far-field observables. Throughout the analysis, we consider spontaneous emission from an excited state as well as two different pump field setups, and contrast the two extreme cases of non-interacting and strongly interacting atoms. For the latter case, the two-excitation submanifold contains a two-body bound state, and we find that the two cases lead to different far-field signatures. Finally we exploit these signatures to characterize the wavefunctions of the collective eigenstates. For this, we identify a direct relation between the collective branching ratio and the momentum distribution of the collective eigenstates' wavefunction. This provides a method to proof the existence of certain collective eigenstates and to access their wave function without the need to individually address and/or manipulate single atoms.
