Capillary Interfacial Tension in Active Phase Separation (2021)
Journal Article
Fausti, G., Tjhung, E., Cates, M., & Nardini, C. (2021). Capillary Interfacial Tension in Active Phase Separation. Physical Review Letters, 127(6), Article 068001. https://doi.org/10.1103/physrevlett.127.068001

In passive fluid-fluid phase separation, a single interfacial tension sets both the capillary fluctuations of the interface and the rate of Ostwald ripening. We show that these phenomena are governed by two different tensions in active systems, and c... Read More about Capillary Interfacial Tension in Active Phase Separation.

Thermodynamics of Active Field Theories: Energetic Cost of Coupling to Reservoirs (2021)
Journal Article
Markovich, T., Fodor, É., Tjhung, E., & Cates, M. E. (2021). Thermodynamics of Active Field Theories: Energetic Cost of Coupling to Reservoirs. Physical Review X, 11(2), Article 021057. https://doi.org/10.1103/physrevx.11.021057

The hallmark of active matter is the autonomous directed motion of its microscopic constituents driven by consumption of energy resources. This motion leads to the emergence of large-scale dynamics and structures without any equilibrium equivalent. T...

Analogies between growing dense active matter and soft driven glasses (2020)
Journal Article
Tjhung, E., & Berthier, L. (2020). Analogies between growing dense active matter and soft driven glasses. Physical Review Research, 2(4), Article 043334. https://doi.org/10.1103/physrevresearch.2.043334

We develop a minimal model to describe growing dense active matter such as biological tissues, bacterial colonies, and biofilms, which are driven by a competition between particle division and steric repulsion. We provide a detailed numerical analysi... Read More about Analogies between growing dense active matter and soft driven glasses.

Self-propulsion of active droplets without liquid-crystalline order (2020)
Journal Article
Singh, R., Tjhung, E., & Cates, M. E. (2020). Self-propulsion of active droplets without liquid-crystalline order. Physical Review Research, 2(3), Article 032024(R). https://doi.org/10.1103/physrevresearch.2.032024

The swimming of cells, far from any boundary, can arise in the absence of long-range liquid-crystalline order within the cytoplasm, but simple models of this effect are lacking. Here, we present a two-dimensional model of droplet self-propulsion invo... Read More about Self-propulsion of active droplets without liquid-crystalline order.

Shear-Induced First-Order Transition in Polar Liquid Crystals (2019)
Journal Article
Markovich, T., Tjhung, E., & Cates, M. E. (2019). Shear-Induced First-Order Transition in Polar Liquid Crystals. Physical Review Letters, 122(8), Article 088004. https://doi.org/10.1103/physrevlett.122.088004

The hydrodynamic theory of polar liquid crystals is widely used to describe biological active fluids as well as passive molecular materials. Depending on the “shear-alignment parameter”, in passive or weakly active polar fluids under external shear,... Read More about Shear-Induced First-Order Transition in Polar Liquid Crystals.

Cluster Phases and Bubbly Phase Separation in Active Fluids: Reversal of the Ostwald Process (2018)
Journal Article
Tjhung, E., Nardini, C., & Cates, M. E. (2018). Cluster Phases and Bubbly Phase Separation in Active Fluids: Reversal of the Ostwald Process. Physical Review X, 8(3), Article 031080. https://doi.org/10.1103/physrevx.8.031080

It is known that purely repulsive self-propelled colloids can undergo bulk liquid-vapor phase separation. In experiments and large-scale simulations, however, more complex steady states are also seen, comprising a dynamic population of dense clusters...
