High-Pressure Phase Stability and Superconductivity in Hydrogen-Rich and Transition-Metal Systems
This community investigates the structural, electronic, and magnetic behavior of materials under extreme pressure and temperature, with a specific focus on identifying stable phases and superconducting properties in hydrogen-rich compounds and transition-metal systems.
The work centers on determining phase diagrams and crystal structures using first-principles calculations, molecular dynamics, and density functional theory. Key experimental methods include diamond anvil cell compression, shock compression, and X-ray diffraction. The research frequently targets hydride superconductors, iron-based superconductors, and the electronic structure of metals like iron, hydrogen, and carbon. Machine learning and Monte Carlo simulations are increasingly used to predict stability and optimize material properties under these extreme conditions.
This research is most prominent in the study of iron, where it constitutes 0.7% of all tracked iron research and accounts for 2,660 papers. It also represents 0.4% of carbon research (3,169 papers) and 0.4% of hydrogen research (2,534 papers).
The community comprises 27,328 papers, primarily published in Physical Review B, Journal of Applied Physics, and Physical Review Letters.
Recent work continues to focus on the maximum critical temperature of conventional superconductors at ambient pressure and the development of machine learning workflows for the inverse design of functional materials.
