A fragmentation approach to quantum calculation of large molecular systems

Fragmentation method has opened a new door for the development of quantum mechanical methods and their applications to large molecules. In the past decade, we have evidenced much progress in this field, and this development is believed to be continued in the future. This article provides a brief overview on the recent development of fragmentation-based methods for electron structure calculation of large molecular systems, with highlight on contribution by researchers from China in this field.
