“…In recent years, quantum optics with x rays has become an active field of research [1][2][3][4][5][6], driven by the progress in high photon intensities and beam quality at modern light sources [6][7][8][9]. As one promising platform, Mössbauer nuclei have received considerable attention.…”

“…While progress has largely been enabled by the "source driven revolution" [9] in the x-ray regime, it is likely that it will not be sufficient for the establishment of more general x-ray quantum optical methods including nonlinear and correlated quantum phenomena. Instead, the development of novel control techniques and target optimizations as well as novel physical platforms will be paramount [12].…”

We develop two ab initio quantum approaches to thin-film x-ray cavity quantum electrodynamics with spectrally narrow x-ray resonances, such as those provided by Mössbauer nuclei. The first method is based on a few-mode description of the cavity, and promotes and extends existing phenomenological few-mode models to an ab initio theory. The second approach uses analytically known Green's functions to model the system. The two approaches not only enable one to ab initio derive the effective few-level scheme representing the cavity and the nuclei in the low-excitation regime, but also provide a direct avenue for studies at higher excitation, involving nonlinear or quantum phenomena. The ab initio character of our approaches further enables direct optimizations of the cavity structure and thus of the photonic environment of the nuclei, to tailor the effective quantum optical level scheme towards particular applications. To illustrate the power of the ab initio approaches, we extend the established quantum optical modeling to resonant cavity layers of arbitrary thickness, which is essential to achieve quantitative agreement for cavities used in recent experiments. Further, we consider multilayer cavities featuring electromagnetically induced transparency, derive their quantum optical few-level systems ab initio, and identify the origin of discrepancies in the modeling found previously using phenomenological approaches as arising from cavity field gradients across the resonant layers.

“…A very appealing application of NIS at an XFELO emerges from the fact that NIS essentially provides a snapshot of lattice dynamics at the very moment when the probing X-ray pulse hits the sample [86]. This will allow for studies of non-equilibrium lattice dynamics where a pump pulse selectively populates vibrational excitations, whereas the probe pulse detects the spectrum of these excitations at the moment of probing.…”

An X-ray free-electron laser oscillator (XFELO) is a new type of hard X-ray source that would produce fully coherent pulses with meV bandwidth and stable intensity. The XFELO complements existing sources based on self-amplified spontaneous emission (SASE) from high-gain X-ray freeelectron lasers (XFEL) that produce ultra-short pulses with broad-band chaotic spectra. This report is based on discussions of scientific opportunities enabled by an XFELO during a workshop held at SLAC on June 29 -July 1, 2016 [1].
