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…
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…
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…
Cross-linking of micelles by gemini surfactants
Prabal K. Maiti, Kurt Kremer, Oliver Flimm +2
We investigate the effects of gemini surfactants, telechelic chain and lipids on the nature of micelles formed by conventional single-tail surfactants in water by carrying out Mont…
A new cellular automata model for city traffic
A. Schadschneider, D. Chowdhury, E. Brockfeld +3
We present a new cellular automata model of vehicular traffic in cities by combining ideas borrowed from the Biham-Middleton-Levine (BML) model of city traffic and the Nagel-Schrec…
