ABSTRACT

Number of particles in simple liquids, such as water, is normally beyond the Avogadro number, and as a result fluctuations in flows of simple liquids are not crucial. However, complex fluids, such as blood stream, contain far less particles and fluctuations in these flows are significant, let alone the role of particle shape and friction. In KIAS, we applied ideas of stochastic thermodynamics for the investigation of fluctuations in complex fluids. A recent paper by the Cambridge complex fluid group entitled "Power fluctuations in sheared amorphous materials: A minimal model" [ https://arxiv.org/abs/2106.12962] has given a full mathematical derivation of our work. In this talk, I will discuss this paper and compare the results and predictions of that paper with those of ours.
