Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 227-238, February 2026.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Quantum Engineering of Landau Levels Using Isotopes in Graphene‐Like Graphite

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
We demonstrate that 13C$^{13}{\rm C}$‐doping in graphene‐like graphite produces a sizable splitting of the Landau level transitions in the magneto‐Raman spectra, a signature of an effective gauge field or pseudomagnetic field on the scale of 0.2 Tesla.

Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

Small, Volume 22, Issue 7, 2 February 2026.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

Sound Velocities and Structural Transitions of Endmember and Fe, Al, Mg, Ti‐Bearing CaSiO3 Glasses Up to 23 GPa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The study of silicate glasses is important to understand the physical and chemical properties of silicate melts under high‐pressure conditions relevant to planetary interiors. We conducted in situ Brillouin spectroscopy measurements on two endmember, low‐impurity CaSiO3 glasses and one Fe, Al, Mg, Ti‐bearing CaSiO3 glass up to 23 GPa.
