Logarithmic conformal field theory
In theoretical physics, a logarithmic conformal field theory is a conformal field theory in which the correlators of the basic fields are allowed to be logarithmic at short distance, instead of being powers of the fields' distance. Equivalently, the dilation operator is not diagonalizable.
Just like conformal field theory in general, logarithmic conformal field theory has been particularly well-studied in two dimensions.
Examples of logarithmic conformal field theories include critical percolation.
