My former student Kishor, colleague Gaurav and I worked on the dynamics of a liquid film flowing down a granular chain. Here are the results of the experiments and some simulations. www.cambridge.org/core/journal...

Cool finding 2: The effect of the bonded dimers extends outward to their nearest neighbors, where we see that both coordination number and pressure are elevated compared to the average. Civil engineering 🏛️ meets statistical physics ⚛️ is a great combination!

Cool finding 1: we can make histograms of all particles (or just the bonded ones), and study how increased rigidity arises as a function of the fraction of bonded pairs. There are stronger interparticle forces present for the dimers (50% tension, 50% compression) compared to the unbonded particles.

I had the pleasure of being a #Fulbright scholar in @granmech.bsky.social 's lab at IISc Bangalore last year, where grad student Abrar Naseer is doing photoelastic force measurements on bonded pairs of particles (my lab just does single ones!) Here's the first preprint: arxiv.org/abs/2507.19214
