摘要: This chapter the additional ingredient of anomalous diffusion, combined with non equilibrium conditions, is studied. The analysis starts a random walk on comb lattice, which can be analytically solvable. A detailed “single file model” then shown and response similar to that one in higher dimensions. ends study ratchet effect fragile glass former. Because presence disorder, under certain an intruder former exhibits subdiffusion. Despite great differences from “family” steady states, also this system it possible observe effect, although characterized by subvelocity due disorder.
