There are examples of CFTs having correlators with logarithms. What are the examples of physical systems exhibiting such logarithmic behaviour (particularly in $d>2$ dimensions)?

$\begingroup$ Do you mean specifically logarithmic CFTs, used for e.g. the description of percolation, or are logarithmic corrections to power law behavior also fine? $\endgroup$– AnyonSep 23, 2018 at 18:40

$\begingroup$ I meant logarithmic CFTs. But to be honest I don't quite understand why conformal theories would allowed to have log terms in correlators, in the first place. $\endgroup$– Physics MoronSep 23, 2018 at 19:38

$\begingroup$ You might already know it, but here is a comprehensive reference for logarithmic CFTs in $d > 2$: arxiv.org/abs/1605.03959 $\endgroup$– M.JoSep 25, 2018 at 15:06

$\begingroup$ Yes, I have seen this paper. But I was mainly interested in applications of LCFTs in physical systems. $\endgroup$– Physics MoronSep 25, 2018 at 15:56
