      abstract     = {We define a stochastic lattice model for a fluctuating
                      directed polymer in d≥2 dimensions. This model can be
                      alternatively interpreted as a fluctuating random path in
                      two dimensions, or a one-dimensional asymmetric simple
                      exclusion process with d−1 conserved species of particles.
                      The deterministic large dynamics of the directed polymer are
                      shown to be given by a system of coupled Kardar-Parisi-Zhang
                      (KPZ) equations and diffusion equations. Using nonlinear
                      fluctuating hydrodynamics and mode coupling theory we argue
                      that stationary fluctuations in any dimension d can only be
                      of KPZ type or diffusive. The modes are pure in the sense
                      that there are only subleading couplings to other modes,
                      thus excluding the occurrence of modified KPZ-fluctuations
                      or Lévy-type fluctuations, which are common for more than
                      one conservation law. The mode-coupling matrices are shown
                      to satisfy the so-called trilinear condition.},
