Welcome to the Yan Group at Lanzhou Jiaotong University
We are committed to the research of the physical properties of two-dimensional materials under high pressure.
Our mission is to fully harness the scientific regulation of two-dimensional layered materials under high pressure, aiming to establish a spin-based information exchange mechanism.

High-Pressure Materials Research: Pioneering Electronic Control for Next-Generation Technologies
Our research group harnesses high-pressure techniques to manipulate interatomic distances at the gigapascal scale, enabling precise control over electronic states and unlocking unprecedented material properties. By compressing matter to mimic extreme environments like planetary cores, we explore transformative phenomena in diverse systems. In transition metal halides, such as FeCl2 and CrI3, pressure induces structural shifts from layered to 3D networks, triggering spin-state flips and emergent magnetism or superconductivity, ideal for spintronic devices. For Group pentelide elements like nitrogen and phosphorus, we investigate phase transitions—from molecular to polymeric forms in N₂ and amorphous-amorphous evolutions in red P—revealing high-energy-density materials and metallization pathways for advanced batteries and optoelectronics. Extending to hydrogen-rich superconductors, including LaH10 and YH6, our work synthesizes hydrides with near-room-temperature Tc, driven by enhanced electron-phonon coupling, paving the way for lossless energy transmission and quantum computing. Through diamond anvil cells, synchrotron probes, and ab initio simulations, we bridge fundamental discoveries to applications, fostering next-generation self-spinning electronics, sensors, and sustainable technologies. This interdisciplinary approach not only deciphers nature's extremes but propels innovations for a quantum future
