Efficient Interaction of Heralded X-Ray Photons with a Beam Splitter.

Physical review letters

Strizhevsky E, Borodin D, Schori A, Francoual S, Röhlsberger R, Shwartz S.
PMID: 34270298
Phys Rev Lett. 2021 Jul 02;127(1):013603. doi: 10.1103/PhysRevLett.127.013603.

We report the experimental demonstration of efficient interaction of multi-kilo-electron-volt heralded x-ray photons with a beam splitter. The measured heralded photon rate at the outputs of the beam splitter is about 0.01  counts/s which is comparable to the rate...

Physical review letters

Kim JH, Peets DC, Reehuis M, Adler P, Maljuk A, Ritschel T, Allison MC, Geck J, Mardegan JRL, Bereciartua Perez PJ, Francoual S, Walters AC, Keller T, Abdala PM, Pattison P, Dosanjh P, Keimer B.

Phys Rev Lett. 2021 Aug 27;127(9):097203. doi: 10.1103/PhysRevLett.127.097203.

Since the discovery of charge disproportionation in the FeO_{2} square-lattice compound Sr_{3}Fe_{2}O_{7} by Mössbauer spectroscopy more than fifty years ago, the spatial ordering pattern of the disproportionated charges has remained "hidden" to conventional diffraction probes, despite numerous x-ray and...

High-magnetic-field lattice length changes in URu2Si2.

Physical review letters

Correa VF, Francoual S, Jaime M, Harrison N, Murphy TP, Palm EC, Tozer SW, Lacerda AH, Sharma PA, Mydosh JA.
PMID: 23368353
Phys Rev Lett. 2012 Dec 14;109(24):246405. doi: 10.1103/PhysRevLett.109.246405. Epub 2012 Dec 11.

We report high-magnetic-field (up to 45 T) ĉ-axis thermal-expansion and magnetostriction experiments on URu(2)Si(2) single crystals. The sample length change ΔL(c)(T(HO))/L(c) associated with the transition to the "hidden order" phase becomes increasingly discontinuous as the magnetic field is raised...

Misfit strain in core-shell nanowires can be elastically released by nanowire bending in case of asymmetric shell growth around the nanowire core. In this work, we investigate the bending of GaAs nanowires during the asymmetric overgrowth by an In

Nat Mater. 2007 Dec;6(12):977-84. doi: 10.1038/nmat2044. Epub 2007 Nov 04.

Quasicrystals are long-range-ordered materials that lack translational invariance, so the study of their physical properties remains a challenging problem. Here, we have carried out inelastic-X-ray- and neutron-scattering experiments on single-grain samples of the Zn-Mg-Sc icosahedral quasicrystal and of the...

The resonant scattering and diffraction beamline P09 at PETRA III is designed for X-ray experiments requiring small beams, energy tunability, variable polarization and high photon flux. It is highly flexible in terms of beam size and offers full higher...

Spectral Control of an X-Ray L-Edge Transition via a Thin-Film Cavity.

Physical review letters

Haber J, Gollwitzer J, Francoual S, Tolkiehn M, Strempfer J, Röhlsberger R.

Phys Rev Lett. 2019 Mar 29;122(12):123608. doi: 10.1103/PhysRevLett.122.123608.

By embedding a thin layer of tantalum in an x-ray cavity, we observe a change in the spectral characteristics of an inner-shell transition of the metal. The interaction between the cavity mode vacuum and the L_{III}-edge transition is enhanced,...

Hybrid semiconductor-ferromagnetic insulator heterostructures are interesting due to their tunable electronic transport, self-sustained stray field, and local proximitized magnetic exchange. In this work, we present lattice-matched hybrid epitaxy of semiconductor-ferromagnetic insulator InAs/EuS heterostructures and analyze the atomic-scale structure and...
