Onset of slow dynamics in dense suspensions of active colloids
Antina Ghosh, Sayan Maity, Vijayakumar Chikkadi
Slow relaxation and heterogeneous dynamics are characteristic features of glasses. The presence of glassy dynamics in nonequilibrium systems, such as active matter, is of significa…
Modelling of strain fields in sheared colloidal glasses using Eshelby inclusions
Atharva Pandit, Antina Ghosh, Vijayakumar Chikkadi
When amorphous solids are strained they display elastic deformation at small strain, however, beyond a critical strain they yield and begin to flow plastically. The origin of this…
Direct observation of percolation in the yielding transition of colloidal glasses
Antina Ghosh, Zoe Budrikis, Vijayakumar Chikkadi +3
When strained beyond the linear regime, soft colloidal glasses yield to steady-state plastic flow in a way that is similar to the deformation of conventional amorphous solids. Due…
Connecting Structural Relaxation with the Low Frequency Modes in a Hard-Sphere Colloidal Glass
Antina Ghosh, Vijayakumar Chikkadi, Peter Schall +1
Structural relaxation in hard-sphere colloidal glasses has been studied using confocal microscopy. The motion of individual particles is followed over long time scales to detect th…
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…
Low energy modes and Debye behavior in a colloidal crystal
A. Ghosh, R. Mari, V. K. Chikkadi +3
withdrawn by the author due to double submission in arXiv:1102.4271 .
Density of states of colloidal glasses
Antina Ghosh, Vijayakumar K. Chikkadi, Peter Schall +2
Glasses are structurally liquid-like, but mechanically solid-like. Most attempts to understand glasses start from liquid state theory. Here we take the opposite point of view, and…
