Title: Equilibrium-like fluctuation-response relation far from equilibrium
Speaker: 천현명 (University of Michigan)
Abstract: The fluctuation-dissipation theorem (FDT) is a central result of equilibrium statistical physics which links the response of a system to its fluctuations. The great utility of the FDT has stimulated interest in the generalization of it to nonequilibrium situations. However, such generalizations tend to be rather formal and often require the knowledge of the steady-state distribution of the system. Recently, J. A. Owen et al. derived an equilibrium-like FDT valid arbitrarily far from equilibrium for static response in discrete jump processes. We identify a class of perturbations that generalize the equilibrium-like FDT to dynamic response in continuous systems. As a consequence of the new FDT, we derive nonequilibrium Green-Kubo relations for the transport coefficients. Our predictions are analytically and numerically corroborated for model systems.

Title: Cost-precision trade-off relation in animal development
Speaker: Yong-Hyun Song (KIAS)
Abstract: Developmental biology is the study of how animals and plants grow and generate macroscopic structures. Biomolecular processes in development operate out of equilibrium, constantly expending free energy to perform vital functions. Importantly, developmental processes are under evolutionary selective pressure to be accurate and reproducible, while operating under a limited energy budget. In this light, I will introduce fruit fly development as an experimental platform to start exploring the thermodynamic cost of precision in biomolecular processes. Next, I will formulate a thermodynamic principle involving morphogens that mediate biological pattern formation. According to this principle, there is a cost-effective optimal strategy by which developing animals can generate precise biological patterns at minimal thermodynamic cost. Remarkably, the dynamical properties of well characterized morphogens are revealed to be governed by our principle, which underscores the thermodynamic cost as an important physical constraint in biological pattern formation.
