Directed polymers with constrained winding angle [PDF]

open access: yesPhysical Review E, 2005
In this article we study from a non-perturbative point of view the entanglement of two directed polymers subjected to repulsive interactions given by a Dirac $ -$function potential. An exact formula of the so-called second moment of the winding angle is derived.
