比如在http://arxiv.org/pdf/1311.1646v1.pdf提到过 a way was found to construct the linear response space for general choices of the MPS gauge in terms of the tangent space vectors
涉及了 tangent space vectors,
在http://arxiv.org/pdf/1405.1225.pdf提到了Grassmann manifold "An SD is therefore described by the Grassmann manifoldUL/(UN × UL−N ), with Uk the unitary group of k × k unitary matrices."
有哪位对微分几何与量子化学比较有感觉的吗?
也许有人会说,我可以把深奥的数学概念用简单的图象来理解,所以就不需要这些微分几何的概念了(费曼与数学家的故事?)不过我觉得,如果谁对这方面很有感觉,也许可以开启一扇新世界的大门

就好像~~~
