【摘要】

：

Pentiptycene[1,2] has the unique H-shaped structure, which is inherently different from the Y-shaped scaffold of triptycene.Thus, pentiptycene derivatives can be used as a new class of useful building

基于热力学积分方法和Monte Carlo的配分函数计算

热力学积分(Thermodynamic Integration,TI)方法是一种基于平衡态统计力学系综理论的计算系统配分函数的方法[1,2]。通过将积分变量设定为β=1/kBT,我们把Monte Carlo模拟和TI方法结合在一起,系统计算了不同大小的二维Ising Model和Potts Model的配分函数,并较为精细地测试了其配分函数的精度对积分中β取值的数量以及体系温度的依赖性。

全局驱动下耦合随机激发系统的倍周期分岔

我们在Prager等的著名三态模型基础上提出了一个新的三态模型。该模型的三个状态分别与心肌细胞钙离子释放单元的激发态、不应期态和恢复态对应，是描述心肌细胞单个钙释放单元内钙离子循环的简单模型。用该三态模型构建了一个局部耦合的二维格点系统，数值模拟和理论分析了全局周期驱动下的该耦合系统的聚集行为。

生物高分子网络及液晶胶体中的随机场研究

我们研究无序软物质体系中随机场性质。具体而言，我们关注的对象是由取向之间存在相互作用的高分子链链接而成的系统，如液晶胶体及生物高分子网络等。这类物质的一个显著特征是微观尺度上的多重复杂性与无序性。首先，随机链接过程生成的是无序的网络结构，并且该网络结构受链接时刻系统状态的影响。

有限时间尺度内与分子取向相关的不对称自由扩散

使用分子动力学研究方法，我们发现具有不对称结构的纳米颗粒(分子)在皮秒到纳秒的有限时间尺度内，其自由扩散和分子取向有关。在100皮秒左右的时间尺度，颗粒朝取向方向扩散的概率比朝相反方向扩散的概率高10％左右，相应的扩散距离为1纳米左右。我们发现这种取向相关扩散的关键在于纳米颗粒受到的阻尼力与其取向相关，以及分子取向调整需要一定的时间。
