Ionic fluctuations in finite volumes: fractional noise and hyperuniformity
Thê Hoang Ngoc Minh, Benjamin Rotenberg, Sophie Marbach
Abstract
scalings when observing diffusing particles in finite domains. The hyperuniform behaviour of charge fluctuations, namely that correlations scale with the area of the observation volume, is preserved in time. Correlations even become proportional to the box perimeter at sufficiently long times. Our results pave the way to understand fluctuations in more complex systems, from nanopores to single-particle electrochemistry.
