Event details

Soap films fascinate children and scientists alike. Historically, their study has helped in the emergence of many concepts that we are familiar with today. However, the physics of these systems is far from being entirely understood. For example, though the fast thinning and drainage of soap films (which ultimately leads to their bursting) is a manifest phenomenon, the physical processes responsible for them remain largely mysterious. It has been observed that this fast thinning is associated with an instability known as "marginal regeneration", and whose classical interpretation invokes the emergence of thin regions of film near the borders of the frame. In this seminar, we will present a mechanism for the appearance of such thin regions, and try to understand how these can lead subsequently to the marginal regeneration instability.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
