Abstract
UNUSUAL TIME (4pm)!
Zoom link: https://maths-cam-ac-uk.zoom.us/j/94018037756
An active particle in a box is a minimal model system displaying characteristic properties of active matter such as effective attraction and breaking of detailed balance. In this talk I present analytical results for the steady state properties of this system, including the entropy production rate, showing its derivative is maximal at a point of a qualitative change in the system behavior. In addition, I will discuss the force applied to objects by active particles with spatially inhomogeneous activity. This force has the form of an Archimedes principle in 1D, which is broken and modified in higher dimensions.
