Notability[edit]

This physicist has written (as far as I can see) exactly one paper, but what a paper it was! It has been cited many times (according to google, I ran across a few citations that don't google) and develops the theory of Berezin integral, which is nowadays a ubiquitous technique in theoretical physics. The topic is very, very notable, so I assume the inventor is too.Likebox (talk) 21:34, 27 August 2008 (UTC)[reply]

Well known Experimental Physicist D. J. Candlin[edit]

Is this the same person?Likebox (talk) 04:17, 28 August 2008 (UTC)[reply]

No theory of Berezin integral[edit]

We analyzed carefully the cited paper by D. J. Candlin. There is no theory of Berezin integration there, only some anticipation of it.

I think that this subject deserves a wider discussion involving both physicists and mathematicians, and not just someone's arbitrary opinions.

If you read the paper attentively, you will see that it develops the whole theory. This paper is cited by knowledgable authors as the source of grassman techniques in modern physics. For example, Mandelstam takes care to cite it. The only other source is Berezin's textbook, a decade later, which does not make claims to have developed the technique.

The paper defines the anticommuting state space by Grassman algebra, and it shows that the sum over intermediate Fermionic states is reproduced by the integral defined over the grassman variables. There is no prior source, the closest is Schwinger's heuristic action principle. This paper develops the methods carefully, in the manner called "Fermionic coherent states" by Negele and Orland, a method which is repeated, without claims of originality, in Berezin's textbook.

I don't know what you mean when you say you "analyzed carefully" the cited paper. If you read it, it develops the entire theory completely and correctly. Please be more specific about what you think is missing.Likebox (talk) 03:18, 18 October 2009 (UTC)[reply]

Interesting discussion! "If you read the paper attentively, you will see that it develops the whole theory" - of course not! The theory of Berezin integral is a mathematical theory going far beyond such simple notions as coherent states. Can I ask you to kindly read the paper http://arxiv.org/abs/1202.3930 (for instance)? Thank you in advance. Plf57 (talk) 16:24, 3 November 2012 (UTC)[reply]
