100 years of Einstein's theory of Brownian motion: from pollen grains to protein trains
Debashish Chowdhury
Experimental verification of the theoretical predictions made by Albert Einstein in his paper, published in 1905, on the molecular mechanisms of Brownian motion established the exi…
Evolutionary ecology in-silico: Does mathematical modelling help in understanding the "generic" trends?
Debashish Chowdhury, Dietrich Stauffer
Motivated by the results of recent laboratory experiments (Yoshida et al. Nature, 424, 303-306 (2003)) as well as many earlier field observations that evolutionary changes can take…
Collective effects in traffic on bi-directional ant-trails
Alexander John, Andreas Schadschneider, Debashish Chowdhury +1
Motivated by recent experimental work of Burd et al., we propose a model of bi-directional ant-traffic on pre-existing ant-trails. It captures in a simple way some of the generic c…
Self-organized patterns and traffic flow in colonies of organisms: from bacteria and social insects to vertebrates
Debashish Chowdhury, Katsuhiro Nishinari, Andreas Schadschneider
Flocks of birds and schools of fish are familiar examples of spatial patterns formed by living organisms. In contrast to the patterns on the skins of, say, zebra and giraffe, the p…
Anomalous fundamental diagrams in traffic on ant trails
Andreas Schadschneider, Debashish Chowdhury, Alexander John +1
Many insects like ants communicate chemically via chemotaxis. This allows them to build large trail systems which in many respects are similar to human-build highway networks. Usin…
A cellular-automata model of flow in ant-trails: non-monotonic variation of speed with density
Debashish Chowdhury, Vishwesha Guttal, Katsuhiro Nishinari +1
Generically, in models of driven interacting particles the average speed of the particles decreases monotonically with increasing density. We propose a counter-example, motivated b…
