| Jun 22, 2010 at 21:56 | comment | added | endian | Thanks. I had asked for a script as I wanted to be certain the the 1/sinh^4 expression was completely correct. Onsager didn't quote it that way, instead it came out as a particularly nasty looking integration, and Yang just confused me even further. I shall go with the analytic expression above though, although it obviously breaks down right at the phase transition. | |
