Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Quasi-invariant theorem on the Gaussian path space
高斯路径 空间 准不变定理
2023/4/27
In this talk, we will first introduce a class of Gaussian processes, and prove the quasi-invariant theorem with respect to the Gaussian Wiener measure, which is the law of the associated Gaussian proc...
A novel construction of complex-valued Gaussian processes with arbitrary spectral densities and its application to excitation energy transfer
complex-valued Gaussian processes arbitrary spectral densities application to excitation energy transfer
2014/9/24
The recent experimental discoveries about excitation energy transfer (EET) in light harvesting antenna (LHA) attract a lot of interest. As an open non-equilibrium quantum system, the EET demands more ...
软质聚氯乙烯分子网络及其Gaussian模量
软质聚氯乙烯 分子网络结构 Gaussian模量 增塑剂 填料 丁腈橡胶
2009/11/13
采用应力松弛实验及Haward模型, 研究了增塑剂含量、填料[CaCO3、炭黑(CB)]和丁腈橡胶(NBR)对软质聚氯乙烯(PPVC)的分子链缠结网络结构、分子链滑移及Gaussian模量的影响. 结果表明, 在PPVC主网络达到极限伸长之前, PPVC材料的粘弹行为能很好地符合Haward模型. 增塑剂、CaCO3和CB虽然不改变主网络的缠结结构, 并且主网络的极限伸长不变, 但增塑剂可以降低主...
Gaussian factorization of hydrodynamic correlation functions and mode-coupling memory kernels
Gaussian factorization hydrodynamic correlation functions mode-coupling memory kernels
2014/9/24
A simple method to determine mode-coupling memory functions in generalized Langevin equations is obtained by explicitly expressing the random force of the slow hydrodynamic modes in terms of pair inte...
