“…81 X rays have been shown to be an enabling tool for nuclear quantum optics as well as studies of collective and virtual effects in the interaction of identical atoms with single photons. 82,83 For instance, it has been shown that the dynamics of M€ ossbauer nuclei can be coherently controlled using an x-ray double-pulse, 84 and that one-photon superradiance and Dicke state superradiance can be achieved using an ensemble of nuclei. [85][86][87][88] An ensemble of nuclei can also be used to shape the waveform of gamma-ray photons coherently, providing a source of single-photon, ultrashort gamma ray pulses with controllable waveforms.…”

The science of x-rays is by now over 125 years old, starting with Wilhelm R€ ontgen's discovery of x-rays in 1895, for which R€ ontgen was awarded the first Nobel Prize in Physics. X-rays have fundamentally changed the world in areas, including medical imaging, security scanners, industrial inspection, materials development, and drugs spectroscopy. X-ray science has been so far responsible for over 25 Nobel Prizes in Physics, Chemistry, and Medicine/Physiology. With x-ray generation being a highly commercialized, widely adopted technology, it may appear that there is little left to discover regarding the fundamentals of x-ray science. Contrary to this notion, recent years have shown renewed interest in the research and development of innovative x-ray concepts. We highlight, in this Perspective, promising directions for future research in x-ray science that result from advances in quantum science and in nanomaterials. Specifically, we describe three key opportunities for advancing x-ray science in the near future: (1) emerging material platforms for x-ray generation, especially 2D materials and their heterostructures; (2) free-electron-driven emission of entangled photon-photon and electron-photon pairs for x-ray quantum optics; and (3) shaping free-electron wavepackets for controllable x-ray emission. These research directions could lead to improvements in x-ray resonance fluoroscopy, high-contrast x-ray imaging, stimulated coherent x rays, x-ray superradiance, and other prospects for x-ray quantum optics.

“…Such cavities thus form a promising platform to implement quantum optical schemes at hard X-ray energies, which are otherwise unavailable due to the lack of suitable X-ray driving fields. For this purpose, the possibility to control the quantum optical parameters is key to implement more advanced quantum optical level schemes [23,32]. The calculations in Fig.…”

“…For example, in nano-photonics, where complex mode environments can be engineered [19] and losses are often sizable [20], the question of how to describe quantum dynamics in complex and absorptive electromagnetic environments has sparked recent theoretical interest [21,22]. Another example is the emerging platform of X-ray cavity QED with ensembles of Mössbauer nuclei [23]. It uniquely combines the possibility of high-precision spectroscopy at X-ray energies using the extreme Q-values of the involved nuclear resonances with cavities which are restricted to the leaky and absorptive regime due to the low refractive index contrast at hard X-ray energies.…”

A practical framework is developed to characterize multi-mode effects on quantum systems coupled to lossy resonators. By relating a generic quantum optical few-mode model to the Mittag-Leffler pole expansion of the cavity's classical Green's function, we identify three distinct classes of multimode effects in the loss-dominated regime. We show that these effects are crucial for understanding spectroscopic signatures in leaky and absorptive resonators, and that they further provide a tuning knob to design artificial quantum systems through such environments. Both aspects are illustrated using examples in X-ray cavity QED with Mössbauer nuclei.

“…Recently, the composite pulse technique has been used for the population transfer in the twostate nuclear systems [50]. Recognizing Mössbauer effect in the late 1960 s, methods based on this effect were presented in order to investigate the interaction of x-ray laser with the which can be referred to Greenʼs function method [51], S-matrix and R-matrix methods [52][53][54][55][56][57][58][59][60] and ab initio theory [61][62][63][64]. Also, new studies have been conducted based on FEL technique, which could be the echo of FEL pulse area control for nuclear state engineering and drive nuclear Mössbauer transitions up to transient nuclear population inversion [65][66][67].…”

The complete population transfer from the ﬁrst state to the ﬁfth one in a ﬁve-state nuclear system that interacts with four X-ray laser pulses has been theoretically studied using the chain-STIRAP technique. In this scheme, it is assumed that the accelerated nucleus interacts with four X-ray laser pulses, and the relativistic factor is adjusted so that the resonance condition is established between the X-ray laser frequencies and the transition frequency of the nucleus. In this study, by establishing the adiabatic condition, the Hamiltonian of the system remains in the dark state. Therefore, the second and fourth states are not populated during the time evolution. Also, to eliminate the population of the third state during the interaction, the middle pulses are considered more signiﬁcant compared to the ﬁrst and last pulses. For the numerical study, 168Er is considered and, it is shown that the population is completely transferred from the ﬁrst state to the ﬁfth state.
