目前的研究课题及展望:

探索具有奇异物理性质的新材料体系是推动凝聚态科学发展的强大动力。在这方面,高压技术具有独特的、不可取代的地位,在现代凝聚态物理的研究中正发挥越来越重要的作用。作为与温度同等重要的热力学参量,高压可以在很大程度上决定许多固态反应的方向和速率,在高温高压条件下能够合成出许多常压条件下不存在的新材料体系。通过施加高压还可以改变决定材料物性非常关键的参数---原子间距离,从而可以精确的调控物性;将超高静水压和极低温、强磁场等极端条件结合在一起,可以探索材料在这些极端激励下的响应,能够揭示出许多奇特并且具有潜在应用价值的物理现象。本人已建立起集高压材料合成与高压物性表征于一体的极端条件实验室,开展综合极端条件下的新材料和物理现象探索。
