Much is known about the geometry of road networks within cities, and how these vary with city size and level of economic development. Less is known about how these structures influence the flows of people and activity within cities, and how that activity in turn feeds back to shape road network geometry. Read more
Since the pioneering work of Wigner in the 50’s, random matrix theory has been playing a crucial role in the understanding of several problems in physics, such as the statistics of nuclear energies, quantum chaos and disordered electronic systems. Read more
LML External Fellow Yuzuru Sato has recently reported the experimental evidence of the existence of stochastic chaos in a turbulent swirling flow. Together with co-authors (D. Faranda, B. Saint-Michel, C. Wiertel, V. Padilla, B. Dubrulle, and F. Daviaud), he shows that the experimental attractor can be modeled by a random strange attractor in stochastic Duffing equations. The article is published in Physical Review Letters: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.119.014502 Read more
During the 2016 LML summer school, Max and I ended up discussing the irreproducibility crisis in science, and that led to a draft manuscript, published today on the arXiv:1706.07773, see also this earlier blog post. Over the last few years several (apparently reproducible!) studies have come out that confirm the crisis. For instance, a survey of scientists, conducted by Nature, found that 70% of respondents had at some point tried but failed to reproduce a published result.

LML External Fellow Isaac Perez has completed and submitted his joint paper titled ‘Level compressibility for the Anderson model on regular random graphs and the absence of non-ergodic extended eigenfunctions’ to Physical Review Letters. Working alongside Fernando Metz from the University of Santa Maria, Brazil, the full paper can be accessed here. Read more
LML Fellows Ole Peters and Alex Adamou have launched a blog called Ergodicity Economics, to accompany their growing set of lecture notes and provide background information to LML’s economics project as it progresses.
The AIP journal Chaos announced today its most-read papers of 2016. Leading the list is “Evaluating gambles using dynamics” by LML resident Fellow Ole Peters and Santa Fe Institute Professor Murray Gell-Mann.
Yonatan Berman and LML Fellows Ole Peters and Alex Adamou have published a substantially extended version of their recent paper on American wealth distributions Read more
