Upcoming events

The AMRC hosts a series of seminars on subjects in statistical physics and fluid dynamics. As we have close links with physics and mathematics groups at Warwick, we also list relevant events there.

Event

Title: Anton Souslov (Bath), Chiral Active Metamaterials
Start date: February 14
Start time: 01:00 pm
End time: 02:00 pm
Organizer: Gareth Alexander
Location: PS1.28
Description: 

Active liquids are composed of self-driven microbots that endow the liquid with a unique set of mechanical characteristics. I will present two designs for materials exhibiting topological states: one using periodic confinement of an active liquid and another using a bulk fluid without periodic order. In a periodic lattice, geometry of confinement controls the structure of topological waves. Without periodic order, topological edge waves can arise in a rotating fluid as a result of the Coriolis force that breaks Galilean invariance and opens a gap at low frequency. I will explore how the number and spatial profile of topological edge states depends on an anomalous response coefficient called odd (or Hall) viscosity. As the sign of odd viscosity changes, a topological phase transition occurs without closing the bulk band gap. For large odd viscosity, this transverse response can be measured via the profile shape of topologically robust edge waves.
