Descripción
We study the dynamics of an asymmetric intruder in a glass-former model. At equilibrium, the intruder diffuses with average zero velocity. After an abrupt quench to T deeply under the mode-coupling temperature, a net average drift is observed, steady on a logarithmic time scale. The phenomenon is well reproduced in an asymmetric version of the Sinai model. The sub-velocity of the intruder grows with T eff / T , where T eff is defined by the response/correlation ratio, corresponding to a general behavior of thermal ratchets when in contact with two thermal reservoirs.
