Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization
Annalen der Physik, Volume 538, Issue 1, January 2026.A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

Case Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.Aim The aim of this study is to report an extremely rare case of corneal annular opacities, incidentally found in a patient referred for age related cataract surgery. Additional anterior segment particularities were detected in this patient. Methods Clinical and imaging methods were employed for a rigorous ophthalmological examination; a full systemic ...

Advanced Science, Volume 12, Issue 44, November 27, 2025.Grain boundaries endow nanocrystalline metals with unique functions but suffer thermal instability. In boron‐segregated platinum, stability depends critically on segregation level—sub‐equilibrium concentrations strengthen boundaries, whereas oversaturation induces decohesion.
