"Logarithmic correlation functions for critical dense polymers on the cylinder" by Alexi Morin-Duchesne and Jesper Lykke Jacobsen has received the Select label. Warm congratulations to the authors!



In this paper, the authors have studied the complex issue of correlation functions in the dense polymer problem. Demonstrating formidable mathematical skills, they are able to express the results in terms of integral formulae and hypergeometric functions. These lattice results were then used to compute structure constants and ratios that appear in the operator product expansions of the boundary condition changing fields. The log-conformal field theories presented in this paper are of special interest in the field of condensed matter theory, as they represent the case where some of the fields are logarithmic instead of primary and thus do not undergo simple multiplicative scale changes under dilation. These results can lead to better understanding of many interesting models like the sandpile model, dense polymers, and critical percolation.
