(David) author Vainstein, Mendeli H. author Rubí Capaceti, José Miguel author Hänggi, Peter author 2010-07-05T10:28:34Z 2010-07-05T10:28:34Z 2008 We present a novel scheme for the appearance of stochastic resonance when the dynamics of a Brownian particle takes place in a confined medium. The presence of uneven boundaries, giving rise to an entropic contribution to the potential, may upon application of a periodic driving force result in an increase of the spectral amplification at an optimum value of the ambient noise level. The entropic stochastic resonance, characteristic of small-scale systems, may constitute a useful mechanism for the manipulation and control of single molecules and nanodevices.
