HPSynR Research Interests
The group develops high-pressure science as a powerful and clean tuning dimension to explore emergent phenomena in quantum and functional materials, discover metastable states, and probe matter under extreme conditions.
1. Quantum Materials under Pressure
高压调控量子材料：超导、电荷序与拓扑相变
The group investigates the evolution of quantum states under pressure, leveraging pressure as a continuous and chemical-free tuning parameter to uncover the interplay between superconductivity, topological transitions, charge ordering, and magnetism in correlated materials. Significant advances have been achieved in nickelates, layered transition metal chalcogenides, and quasi-one-dimensional systems, highlighting the group's strength in discovering and understanding emergent quantum states under pressure.
2. Pressure-Engineered Functional Materials
压力工程功能材料：光电、发光、非线性光学与铁电光伏
The group extends high-pressure techniques to functional materials, systematically tuning band structures, local coordination environments, excitonic behaviors, symmetry breaking, and ferroelectric relaxation dynamics. This has led to the development of a “pressure engineering” strategy for enhancing material functionalities, including improved luminescence, optoelectronic response, nonlinear optical properties, and ferroelectric photovoltaic effects in halide perovskites and related systems.
3. Metastable Materials and High-Pressure Synthesis
高压诱导新材料与亚稳相合成：从新结构发现到常压保留
A central focus of the group is the discovery of new structures and phases under pressure, along with understanding their kinetic pathways and stabilization mechanisms. The group aims to translate high-pressure phases into recoverable metastable materials at ambient conditions, enabling practical applications. Notable achievements include the synthesis of bulk hexagonal diamond, metastable polymorphs, and strategies for retaining high-pressure phases.
4. Dynamic Compression and Extreme States of Matter
动态压缩与极端条件原位表征：面向地学与超高压前沿
Beyond static compression, the group explores materials under shock compression and laser-driven extreme conditions, employing time-resolved techniques to probe structural evolution on nanosecond timescales. These studies contribute to understanding materials behavior relevant to geophysics, planetary science, and warm dense matter, bridging condensed matter physics and extreme environment science.
5. High-Pressure Methods and In Situ Characterization
高压实验方法与多场耦合原位表征平台
The group actively develops multi-field coupled experimental platforms integrating high pressure, low temperature, and time-resolved in situ probes. These methodological advances enable precise calibration, structural determination, and dynamic measurements, providing critical tools for studying complex materials under extreme conditions.
