Dynamic scaling in natural swarms
WebIn some instances, ˘scales with the system’s size, giving rise to scale-free correlations [2, 7, 9]. Strikingly, another key hallmark of statistical physics, namely dynamic scaling [10, 11], has been veri ed in the case of natural swarms of insects [12]. WebCollective behaviour in biological systems pitches us against theoretical challenges way beyond the borders of ordinary statistical physics. The lack of concepts like scaling and …

WebAug 17, 2024 · Susceptibility, correlation length, dynamic correlation function and largest Lyapunov exponent obey power laws. Their critical exponents agree with those observed in natural midge swarms, unlike values obtained from the order-disorder transition of the standard Vicsek model which confines particles by artificial periodic boundary conditions. WebIn an attempt to improve this situation, we present here experimental evidence of the emergence of dynamic scaling laws in natural swarms of midges. We find that spatio-temporal correlation functions in different swarms can be rescaled by using a single characteristic time, which grows with the correlation length with a dynamical critical ...

WebDec 1, 2014 · By gathering three-dimensional data on swarms of midges in the field we find that swarms tune their control parameter and size so as to maintain a scaling behavior of the correlation function. As a consequence, correlation length and susceptibility scale with the system’s size and swarms exhibit a near-maximal degree of correlation at all sizes. early start oakleighWebJun 19, 2024 · Dynamic scaling in natural swarms – Nature Physics in Highlights, News, Physical Biology, Statistical Physics & Complexity.
