List of Questions in DFT and answers (for some Qs)

The questions span a wide topics in Physics or sometimes other subjects also. Whenever possible, I try to answer in a separate post and give links to related materials to these question. To see the answer page, click the link ANSWER given at the end of the question.

1. A multi-electron wave function should obey Anti-symmetric priciple, i.e. the sign of the wave function should change sign if two electrons are interchanged (or swapped). Does Kohn-Sham orbitals obey this principle? Is there any description related to this? ANSWER

Peer-review: What it is like?

How is peer-review like?

Most of the time peer-review improves the manuscript. Here is an illustration (credit:redpenblackpen.jasonya.com) of how peer-review improves your manuscript. Originally, you submit a decent paper and if the manuscript is reviewed properly, surely it will transform your decent manuscript to a luxury car.

While peer-review some times gives so much pain for the authors, peer-review methodology works well.
"Yes. Exceptions too. There are so many research works which at the end got Nobel prize where initially rejected by peer-reviewers (as well as editors). A most recent example would be the first report on the atomically thick, 2D material cleaved from graphite known as Graphene. Firstly, the authors submitted the paper to Nature and it was rejected. Then, the authors made a minor revision in the paper and submitted to Science and it was published. Within 5 years after the publication of this paper, Nobel prize was awarded." This kind of rejections will be covered in another post.

But, here we are going to see so many examples where peer-review system is not that bad.
