Exact fixed point for directed random walks
J J Rajasekaran and S M Bhattacharjee
Show affiliationsThe authors have shown that the renormalization group fixed point for mutually avoiding directed random walks in (d+1) dimensions is exactly 2 pi in where in =2-d, with no higher order terms in in . Since the whole calculation can be carried out to all orders exactly, the model is also significant from a pedagogical point of view.
