Quasi-entropy by log-determinant covariance matrix and application to liquid crystals
Jie Xu
A quasi-entropy is constructed for tensors averaged by a density function on using the log-determinant of a covariance matrix. It serves as a substitution of the entropy fo…

Symmetry-consistent expansion of interaction kernels between rigid molecules
Jie Xu
We discuss the expansion of interaction kernels between anisotropic rigid molecules. The expansion decouples the correlated orientational variables so that it can be utilized to de…

Classifying local anisotropy formed by rigid molecules: symmetries and tensors
Jie Xu
We consider an infinitesimal volume where there are many rigid molecules of the same kind, and discuss the description and classification of the local anisotropy in this volume by…
