Talk:Singlet state

could this page also mention isosinglet? --MarSch 09:32, 25 April 2006 (UTC)

Split
The page mentions four different topics, three of them one-line sentences. This is adequate grounds for proposing a split into separate pages accessible from a disambigation page. However, three of those topics are barely more than one line long, so may not merit a separate page. --B.d.mills 02:30, 3 April 2007 (UTC)

the rotation group SU(2) ???
Well, SU(2) is not the rotation group. Is it the cyclic group SO(2) or the unitary group SU(2) --81.65.198.143 (talk) 13:15, 11 May 2008 (UTC)

I would rather call SU(2) for the special unitary group, or else it would be U(2). —Preceding unsigned comment added by 130.225.102.1 (talk) 12:46, 16 December 2009 (UTC)

Changed rotation group to Lie group following the example in the Doublet state article. Considered special unitary group, but SU(2) already redirects there. — Preceding unsigned comment added by 67.249.203.18 (talk) 14:38, 14 July 2011 (UTC)

Shorten EPR discussion and cite the EPR article instead?
I have cleaned up the discussion of the EPR paradox and mention of Bell's theorem a bit (adding a reference to Bohm who introduced the application of the singlet in this context!). But perhaps this material should be shortened/summarized and reference made to the EPR paradox and Bell's theorem pages instead (moving material from this article into those articles if any of it provides additional useful discussion or clearer presentation of aspects of those topics). — Preceding unsigned comment added by MorphismOfDoom (talk • contribs) 18:31, 22 February 2022 (UTC)
