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.4 p.application/pdfeng(c) American Physical Society, 2008Física estadísticaFísica matemàticaStatistical physicsMathematical physicsinfo:eu-repo/semantics/article563464info:eu-repo/semantics/openAccess
