This article explores groundbreaking research from Rice University, led by physicist Qimiao Si, on quantum critical metals, materials that behave unpredictably at low temperatures. The study focuses on quantum critical points (QCPs), transitional states where materials shift between two distinct phases, such as magnetism and nonmagnetism. At QCPs, quasiparticles—representing collective electron behavior—disappear due to “Kondo destruction,” altering the material’s electronic structure and the Fermi surface. These findings shed light on “strange metals,” which defy conventional physics and exhibit universal behaviors tied to Planck’s constant. The study identifies a phenomenon called dynamical Planckian scaling, linking these behaviors to cosmic patterns, offering insights into developing advanced superconductors. Implications extend to diverse quantum materials, such as iron-based superconductors, enhancing our understanding of complex electronic interactions.

In general, if you enjoy reading this kind of scientific news articles, I would also be keen to connect with fellow researchers based on common research interests in materials science, including the possibility to discuss about any potential interest in the Materials Square cloud-based online platform ( [www.matsq.com](http://www.matsq.com) ), designed for streamlining the execution of materials and molecular modelling simulations!
