Critical role of pinning defects in scroll-wave breakup in active media
S. Sridhar, Anitna Ghosh, Sitabhra Sinha
The breakup of rotating scroll waves in three-dimensional excitable media has been linked to important biological processes. The known mechanisms for this transition almost exclusi…
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…
