Abstract
The simple cubic structure and highly ionic bonding characteristics of Alkali halide NaBr have garnered significant attention in the field of fundamental physics. Previous X-ray diffraction studies revealed a phase transition from B1 to B33 phase in NaBr under pressure. However, the experimental determination of the phase transition pressure suffered from large errors due to the absence of a pressure transfer medium and high-water absorption in NaBr samples. To overcome these limitations, we employ DFT calculations to investigate the phase transition behavior of NaBr up to 40 GPa. Our theoretical analysis reveals a “first-order” phase transition at 25 GPa and provides comprehensive insights into the pressure-dependent physical properties.
期刊介绍：
Physics Letters A offers an exciting publication outlet for novel and frontier physics. It encourages the submission of new research on: condensed matter physics, theoretical physics, nonlinear science, statistical physics, mathematical and computational physics, general and cross-disciplinary physics (including foundations), atomic, molecular and cluster physics, plasma and fluid physics, optical physics, biological physics and nanoscience. No articles on High Energy and Nuclear Physics are published in Physics Letters A. The journal''s high standard and wide dissemination ensures a broad readership amongst the physics community. Rapid publication times and flexible length restrictions give Physics Letters A the edge over other journals in the field.
