The new issue of Optica Quantum is available. A Gold Open Access journal from Optica Publishing Group, Optica Quantum provides a home for high-impact research in quantum information science and technology enabled by optics and photonics. October marks the one-year anniversary of Optica Quantum’s launch in 2023, acknowledged by the Editor-in-Chief and Deputy Editors in their commemorative editorial.

There have been many attempts to create monochromatic metallic materials, but few materials change luster color in response to external stimuli. In a recent breakthrough, researchers from Chiba University have prepared a diacetylene derivative-based metallic luster material that changes from silver to gold under UV irradiation. These findings are expected to find applications in decorative items, printing inks, photomask patterning, UV laser lithography, and cosmetics.

The coupled electronic and nuclear motions within a single molecule are ubiquitous in physics and chemistry, which determine the dominant pathways of energy transfer and charge transfer processes in nearly all chemical reactions. Thus, probing coupled electron-nuclear dynamics on ultrafast time scales is essential not only for our understanding of numerous fundamental processes in physics and chemistry, but also for controlling chemical reactions at the molecular level.

The conservation law is a fundamental tool that significantly aids our quest to understand the world, playing a crucial role across various scientific disciplines. Particularly in strong-field physics, these laws enhance our comprehension of atomic and molecular structures as well as the ultrafast dynamics of electrons.

A new study published in <i>Physical Review Letters</i> provides direct evidence of the breakdown of spin statistics in ion-atom charge exchange collisions. This study was led by scientists from the Institute of Modern Physics of the Chinese Academy of Sciences.
