Are there real-world physical systems to which higher dimensional ($d>3$) Ising models correspond?

2Well in general you can map a relativistic QFT in $d$-spacetime-dimensions to a statistical field theory/statistical physics problem in $d+1$ dimension. – Tobias Fünke Jan 25 '24 at 11:10

4Does this answer your question? Why do we study the Ising model on $\mathbb{Z}^d$ for $d > 3$? – Yvan Velenik Jan 25 '24 at 11:35

1Roger, I think your question has been perfectly answered in the link by @YvanVelenik . If you feel that is not the case, please update your question. – lcv Jan 25 '24 at 12:19

I do not see a link by YanVelenik. More importantly, I do not see the relation between this question and the supposed duplicate, a part for dealing with dimensions higher than the physical ones. – GiorgioP-DoomsdayClockIsAt-90 Jan 25 '24 at 13:43

@GiorgioP-DoomsdayClockIsAt-90. It was this question that I linked to (but my comment disappeared once the question was closed). It is a pretty clear duplicate. – Yvan Velenik Jan 25 '24 at 13:53
