Low energy modes and Debye behaviour in a colloidal crystal
Antina Ghosh, Romain Mari, V. K. Chikkkadi +3
We study the vibrational spectrum and the low energy modes of a three dimensional colloidal crystal using confocal microscopy. This is done in a two-dimensional cut through a three…

Preventing transition to turbulence: a viscosity stratification does not always help
Vijayakumar Chikkadi, A. Sameen, Rama Govindarajan
In channel flows a step on the route to turbulence is the formation of streaks, often due to algebraic growth of disturbances. While a variation of viscosity in the gradient direct…
