We construct tilting modules over Jacobian algebras arising from knots. To a two-bridge knot L [a 1,…, a n], we associate a quiver Q with potential and its Jacobian algebra A. We construct a family of canonical indecomposable A-modules M (i), each supported on a different specific subquiver Q (i) of Q. Each of the M (i) is expected to parametrize the Jones polynomial of the knot. We study the direct sum M=⊕ i M (i) of these indecomposables inside the module category of A as well as in the cluster category. In this paper we consider the special case where the two-bridge knot is given by two parameters a 1, a 2. We show that the module M is rigid and τ-rigid, and we construct a completion of M to a tilting (and τ-tilting) A-module T. We show that the endomorphism algebra End A T of T is isomorphic to A, and that the mapping T↦ A [1] induces a cluster automorphism of the cluster algebra A (Q). This automorphism is of order two. Moreover, we give a mutation sequence that realizes the cluster automorphism. In particular, we show that the quiver Q is mutation equivalent to an acyclic quiver of type T p, q, r (a tree with three branches). This quiver is of finite type if (a 1, a 2)=(a 1, 2),(1, a 2), or (2, 3), it is tame for (a 1, a 2)=(2, 4) or (3, 3), and wild otherwise.
