DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PatC/21/">Im
 aginary multiplicative chaos: different questions from different contexts\
 , and a few answers too</a>\nby Juhan Aru (EPFL Lausanne) as part of Proba
 bility and the City Seminar\n\n\nAbstract\nImaginary multiplicative chaos 
 is formally given by exp(iG)\, where G is a log-correlated Gaussian field 
 in d dimensions.\nIt comes up in several different contexts. For example\n
 - as a analytic continuation of the real multiplicative chaos\, that is ce
 ntral in the probabilistic study of Liouville quantum gravity and Liouvill
 e CFT\;\n- when taking the continuum limit of the spin field for the XOR-I
 sing model\;\n- in relation to the Kosterlitz-Thouless-type of phase trans
 itions.\nIn this talk I will try to explain how imaginary chaos comes up i
 n these contexts\, which questions it brings along\, and how to answer som
 e of these questions. \nThis is a joint work with J. Junnila\, and also pa
 rtly with A. Jego.\n
