1. 受限体系中粒子输运研究
2.活性颗粒物,软物质动力学研究
3.非平衡态统计物理基本问题的研究
4. 低维热传导过程中能量输运性质
布朗运动连接着微观热运动和宏观可观测量,是研究热力学基本问题的理想系统。这种随机运动/涨落在我们生活中无处不在,如股市的涨落,粒子的跨膜传输,颗粒物的输运…我们课题组基于随机过程,对小概率事件展开研究。利用热/随机涨落驱动颗粒物远离平衡态,产生定向运动收获能量。其极限在哪里,是近代热力学与统计物理的关键问题。随着微纳米技术的发展,机器微型化,制备出了本身具有各种功能的马达,如靶向给药,纳米火箭等,我们统称为活性马达。我们课题组将基于这类活性马达,探讨热力学的基本问题,设计更高效的微纳米马达。
