“…Finally, it is worth highlighting that these beam-induced effects will become increasingly relevant for experiments at next generation synchrotrons 37,38 and at free-electron lasers sources 39 . In the latter case, techniques using high intense coherent beams, such as XPCS, are based on fs pulses that have intensities as high as current synchrotron sources provide in one second [40][41][42][43][44][45] . It is therefore likely that the above effects will be greatly amplified by non-linear responses of the system to collective excitations induced by the absorption of very short and intense X-ray pulses.…”

Nowadays powerful X-ray sources like synchrotrons and free-electron lasers are considered as ultimate tools for probing microscopic properties in materials. However, the correct interpretation of such experiments requires a good understanding on how the beam affects the properties of the sample, knowledge that is currently lacking for intense X-rays. Here we use X-ray photon correlation spectroscopy to probe static and dynamic properties of oxide and metallic glasses. We find that although the structure does not depend on the flux, strong fluxes do induce a non-trivial microscopic motion in oxide glasses, whereas no such dependence is found for metallic glasses. These results show that high fluxes can alter dynamical properties in hard materials, an effect that needs to be considered in the analysis of X-ray data but which also gives novel possibilities to study materials properties since the beam can not only be used to probe the dynamics but also to pump it.

“…High-quality, detwinned ortho-II YBa 2 Cu 3 O x single crystals with x = 6.40, 6.43, and 6.48 were selected for this work, corresponding to doping concentrations of p = 0.07 (T c = 35 K), 0.08 ∼ p 1 (43 K), and 0.09 (54 K), respectively. The experiment was carried out at the XCS instrument of the Linac Coherent Light Source [18], to employ the setup that synchronizes the x-ray free electron laser pulses and pulsed magnetic fields [15,17]. Magnetic fields up to 33 T were used to suppress superconductivity to allow for the detection of CDW order at low temperatures.…”

Coincident onset of charge-density-wave order at a quantum critical point in underdoped YBa2Cu3Ox

et al. 2018

The recently demonstrated x-ray scattering approach using a free electron laser with a high field pulsed magnet has opened new opportunities to explore the charge density wave (CDW) order in cuprate high temperature superconductors. Using this approach, we substantially degrade the superconductivity with magnetic fields up to 33 T to investigate the onset of CDW order in YBa 2 Cu 3 O x at low temperatures near a putative quantum critical point (QCP) at p 1 ∼ 0.08 holes per Cu. We find no CDW can be detected in a sample with a doping concentration less than p 1 . Our results indicate that the onset of the CDW ground state lies inside the zero-field superconducting dome, and broken translational symmetry is associated with the putative QCP at p 1 .

“…Dynamics of the conical and skyrmion order parameters in Cu 2 OSeO 3 were measured via time-resolved resonant x-ray scattering at the soft x-ray beamline at the Linac Coherent Light Source (LCLS) with 100 fs resolution and at BL6.02 at the Advanced Light Source (ALS) with 60 ps resolution [20,21]. Both experiments probed the (1, 0, τ ) and (1, τ , 0) scattering peaks, sensitive to conical and skyrmion order [11] with x-ray photon energy of 930 eV, resonant with the Cu Ledge.…”
