Title: Fractional noise in nanopores
Abstract: Fluctuations are ubiquitous in bio and artificial nanopores. Most of the time, fluctuations are seen as a negative feature that impedes for example signal measurements. Yet, biological pores are still able to achieve complex tasks in spite of fluctuations. To investigate the riddle of fluctuations in nanoporous transport, here I explore how fluctuations in the particle number within the pore affect signal measurements. I find that fractional noise emerges naturally as a striking and universal feature. In particular, I will show how fractional noise inherits from an intrinsic property of brownian walks.
