硬芯势 meaning in English

hard-core potential

A generalized bariev model for correlated hopping with a finite range hard - core repulsion is studied in this paper
本文要讨论的是一种具有硬芯势的bariev模型。
Due to the hard core repulsion , the distribution function of electrons was compressed effectively . thus , we hope the new model has different properties from the standard bariev model with open boundary
由于存在硬芯势，电子在链上的分布变得稀疏，开边界的有芯模型具有不同于标准bariev模型的性质。
