Fluctuating chemically active droplets
Guido L. A. Kusters, Noah Ziethen, Michael E. Cates +1
We study size fluctuations of chemically active droplets in the regime of weak reactions and strong phase separation. By combining a thin-interface model for the deterministic drop…
Nucleation and time-reversal symmetry breaking in nonconserved scalar field theories
Noah Ziethen, Michalis Chatzittofi, Michael E. Cates +1
Classical nucleation theory (CNT) describes the formation of a stable phase from a metastable one in terms of a single reaction coordinate that corresponds to the radius of a nucle…
Nonequilibrium nucleation theory for nonconserved fields: from active matter to population dynamics
Michalis Chatzittofi, Noah Ziethen, Cesare Nardini +1
Classical nucleation theory (CNT) describes the formation of a stable phase from a metastable one. In equilibrium systems, it quantifies the free-energy competition between a favor…
Chemically Active Liquid Bridges Generate Repulsive Forces
Noah Ziethen, Frieder Johannsen, David Zwicker
Droplets help organize cells by compartmentalizing biomolecules and by mediating mechanical interactions. When bridging two structures, such droplets generate capillary forces, whi…
Heterogeneous Nucleation and Growth of Sessile Chemically Active Droplets
Noah Ziethen, David Zwicker
Droplets are essential for spatially controlling biomolecules in cells. To work properly, cells need to control the emergence and morphology of droplets. On the one hand, driven ch…
Vascular adaptation model from force balance: Physarum polycephalum as a case study
Sophie Marbach, Noah Ziethen, Karen Alim
Understanding vascular adaptation, namely what drives veins to shrink or grow, is key for the self-organization of flow networks and their optimization. From the top-down principle…
Nucleation of chemically active droplets
Noah Ziethen, Jan Kirschbaum, David Zwicker
Driven chemical reactions can control the macroscopic properties of droplets, like their size. Such active droplets are critical in structuring the interior of biological cells. Ce…
Thermodynamically Consistent Phase-Field Theory Including Nearest-Neighbor Pair Correlations Explains Failure of Mean-Field Reasoning
Kristian Blom, Noah Ziethen, David Zwicker +1
Most of our current understanding of phase separation is based on ideas that disregard correlaions. Here we illuminate unexpected effects of correlations on the structure and therm…
