We present a rigorous mathematical approach of two species channel transportwithin the framework of stochastic thermodynamics, which explains the impact ofinterparticle in-channel interactions. Different from mean field approaches,the model explicitly conserves spatial correlations by considering stochastictransitions between the channel's occupation states. The interparticleinteractions determine the Brownian ratchet like rectifying forces, which thesespecies exert mutually on each other. Perfect coupling of transport emerges byan attractive empty channel and strong repulsive forces between particles ofthe same species. Stochastic transitions are then confined to a subspace withcircular topology, which makes channel flows of both species become equivalent.For opposing concentration gradients, this makes the species with the strongergradient the driving, positive entropy producing one, the other is driven andproduces negative entropy. A differential interaction with less repulsiveforces within particles of one species, but maintenance of this interaction forthe other species, adds a bypass path to this circular subspace. On this path aleak flow of the species with less repulsive interparticle interaction emerges,which is directed parallel to its concentration gradient, and, hence, producespositive entropy. Now, appropriate strong opposing concentration gradients maysimultaneously parallelize flow of their respective species, which makes eachspecies produce positive entropy. The rectifying potential of the species withthe bypass option is diminished, which implies the existence of a gradient ofthe other species, above which its flow and gradient are always parallel.Conversely flow of the less coupled species may always be turned anti-parallelto its gradient by a sufficient strong opposing gradient of the other one.
