# Physical examples of log CFTs

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)?

• Do you mean specifically logarithmic CFTs, used for e.g. the description of percolation, or are logarithmic corrections to power law behavior also fine? Sep 23 '18 at 18:40
• 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. Sep 23 '18 at 19:38
• You might already know it, but here is a comprehensive reference for logarithmic CFTs in $d > 2$: arxiv.org/abs/1605.03959

• Yes, I have seen this paper. But I was mainly interested in applications of LCFTs in physical systems. Sep 25 '18 at 15:56
