If you have a question about this talk, please contact Dr Dimitri M Gangardt. We consider by combinatorial methods the correlation function of k (k is odd) loop-erased random walks in 2D. Starting and ending points of the paths are grouped in a fashion of a k-leg watermelon. For large distance between watermelon extremities, the reunion exponent is (k^2 - 1)/2, in coincidence with known CFT result. Elongating the loop-erased random walks in some direction, we examine how the reunion exponent of k loop-erased random walks is converting into the reunion exponent of k vicious walkers (i.e. world lines of free fermions in (1+1)D). The considered model allows to speculate how by changing the degree of stretching, one can interpolate from the logarithmic Conformal Field Theory to the Random Matrix Theory.
