A Remark on Diffusion of Directed Polymers in Random Environments
We consider a system of random walks or directed polymers interacting with an environment which is random in space and time. Under minimal assumptions on the distribution of the environment, we prove that this system has diffusive behavior with probability one if d > 2 and fl < flo, where flo is defined in terms of the probability that the symmetric nearest neighbor random walk on the d-dimensi...
متن کاملDiffusion of Directed Polymers in a Strong Random Environment
We consider a system of random walks or directed polymers interacting with an environment which is random in space and time. It was shown by Imbrie and Spencer that in spatial dimensions three or above the behavior is diffusive if the directed polymer interacts weakly with the environment and if the random environment follows the Bernoulli distribution. Under the same assumption on the random e...
متن کاملAnomalous diffusion of self-propelled particles in directed random environments.
We theoretically study the transport properties of self-propelled particles on complex structures, such as motor proteins on filament networks. A general master equation formalism is developed to investigate the persistent motion of individual random walkers, which enables us to identify the contributions of key parameters: the motor processivity, and the anisotropy and heterogeneity of the und...
متن کاملA Note on Directed Polymers in Gaussian Environments
We study the problem of directed polymers in gaussian environments in Zd from the viewpoint of a gaussian family indexed by the set of random walk paths. In the zero-temperature case, we give a numerical bound on the maximum of the Hamiltonian, whereas in the finite temperature case, we establish an equivalence between the very strong disorder and the growth rate of the entropy associated to th...
متن کاملBrownian Directed Polymers in Random Environment
We study the thermodynamics of a continuous model of directed polymers in random environment. The environment is given by a space-time Poisson point process, whereas the polymer is defined in terms of the Brownian motion. We mainly discuss: (i) The normalized partition function, its positivity in the limit which characterizes the phase diagram of the model. (ii) The existence of quenched Lyapun...
