Dome-Shaped Superconducting Phase Diagram Linked to Charge Order in LaRuSi
KeYuan Ma, I. Plokhikh, J. N. Graham +17
The interplay between superconductivity and charge order is a central focus in condensed matter research, with kagome lattice systems offering unique insights. The kagome supercond…
Charge orders with distinct magnetic response in a prototypical kagome superconductor LaRuSi
C. Mielke, V. Sazgari, I. Plokhikh +22
The kagome lattice has emerged as a promising platform for hosting unconventional chiral charge order at high temperatures. Notably, in LaRuSi, a room-temperature charg…
Synthesis of Ultra-Incompressible Carbon Nitrides Featuring Three-Dimensional Frameworks of CN4 Tetrahedra Recoverable at Ambient Conditions
Dominique Laniel, Florian Trybel, Andrey Aslandukov +22
More than thirty years ago, carbon nitrides featuring 3D frameworks of tetrahedral CN4 units were identified as one of the great aspirations of materials science, expected to have…
Ultrafast Frustration-Breaking and Magnetophononic Driving of Singlet Excitations in a Quantum Magnet
Flavio Giorgianni, Björn Wehinger, Stephan Allenspach +6
Ideal magnetic frustration forms the basis for the emergence of exotic quantum spin states that are entirely nonmagnetic. Such singlet spin states are the defining feature of the S…
High-Pressure Elasticity Tensor from Thermal Diffuse Scattering
Björn Wehinger, Alessandro Mirone, Michael Krisch
We report on the determination of high-pressure elasticity from thermal diffuse x-ray scattering of magnesium oxide at pressures up to 28 GPa. We find that the full elasticity tens…
Rayleigh anomalies and disorder-induced mixing of polarizations at nanoscale in amorphous solids. Testing 1-octyl-3-methylimidazolium chloride glass
Maria Grazia Izzo, Bjorn Wehinger, Stefano Cazzato +4
Acoustic excitations in topologically disordered media at mesoscale present anomalous features with respect to the Debye's theory. In a three-dimensional medium an acoustic excitat…
Full elasticity tensor from thermal diffuse scattering
Björn Wehinger, Alessandro Mirone, Alexeï Bosak +1
We present a method for the precise determination of the full elasticity tensor from a single crystal diffraction experiment using monochromatic X-rays. For the two benchmark syste…
Electromagnon dispersion probed by inelastic x-ray scattering
Sándor Tóth, Björn Wehinger, Katharina Rolfs +7
Inelastic x-ray scattering with meV energy resolution (IXS) is an ideal tool to measure collective excitations in solids and liquids. In non-resonant scattering condition, the cros…
First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)

We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…
Lattice dynamics of MgSiO perovskite (bridgmanite) studied by inelastic x-ray scattering and ab initio calculations
Björn Wehinger, Alexeï Bosak, Sabrina Nazzareni +9
We have determined the lattice dynamics of MgSiO perovskite (bridgmanite) by a combination of single-crystal inelastic x-ray scattering and ab initio calculations. We observe a…
