Multiferroicity in plastically deformed SrTiO.

Quantum materials have a fascinating tendency to manifest novel and unexpected electronic states upon proper manipulation. Ideally, such manipulation should induce strong and irreversible changes and lead to new relevant length scales. Plastic deformation introduces large numbers of dislocations into a material, which can organize into extended structures and give rise to qualitatively new physics as a result of the huge localized strains.

Impact of Workplace Bullying on Nursing Care Quality: A Comprehensive Review.

Workplace bullying, commonly known as mobbing, persists as a significant problem across various industries, including the healthcare sector. To establish effective interventions and protocols for enhancing the well-being of healthcare workers and patients, it is vital to fully grasp the link between workplace bullying and the quality of nursing care. The analysis highlights the complex link between workplace bullying and nursing care quality, stressing the urgency of addressing this issue due to its wide-reaching impact on individuals and healthcare organizations, ultimately affecting patient safety.

Local inversion-symmetry breaking in a bismuthate high-T superconductor.

The doped perovskite BaBiO exhibits a maximum superconducting transition temperature (T) of 34 K and was the first high-T oxide to be discovered, yet pivotal questions regarding the nature of both the metallic and superconducting states remain unresolved. Although it is generally thought that superconductivity in the bismuthates is of the conventional s-wave type, the pairing mechanism is still debated, with strong electron-phonon coupling and bismuth valence or bond disproportionation possibly playing a role. Here we use diffuse x-ray scattering and Monte Carlo modeling to study the local structure of BaKBiO across its insulator-metal boundary.

Unconventional short-range structural fluctuations in cuprate superconductors.

The interplay between structural and electronic degrees of freedom in complex materials is the subject of extensive debate in physics and materials science. Particularly interesting questions pertain to the nature and extent of pre-transitional short-range order in diverse systems ranging from shape-memory alloys to unconventional superconductors, and how this microstructure affects macroscopic properties. Here we use neutron and X-ray diffuse scattering to uncover universal structural fluctuations in LaSrCuO and TlBaCuO, two cuprate superconductors with distinct point disorder effects and with optimal superconducting transition temperatures that differ by more than a factor of two.

Uniaxial Strain Control of Bulk Ferromagnetism in Rare-Earth Titanates.

The perovskite rare-earth titanates are model Mott insulators with magnetic ground states that are very sensitive to structural distortions. These distortions couple strongly to the orbital degrees of freedom and, in principle, it should be possible to tune the superexchange and the magnetic transition with strain. We investigate the representative system (Y,La,Ca)TiO_{3}, which exhibits low crystallographic symmetry and no structural instabilities.
