From Action Principle to Stochastic Thermodynamics of Elastic and Viscous Active Matter
Valentina Barletta, Michele Lupini, Ian D. Estabrook +6
Motivated by the complex material properties of living matter, we derive a framework of stochastic thermo- and elastodynamics for active materials from the classical principle of l…
True and Quasi Long-Range Order in Malthusian Flocks
Patrick Jentsch, Anna Erzberger
Living matter undergoes continuous turnover. The hydrodynamic theory of Malthusian flocks describes polar active matter with turnover, but its phase diagram and nonlinear scaling b…
Ensemble theory of thermodiffusion
R. Belousov, J. Elliott, A. Erzberger
Heat flow sustained by a temperature difference generates a gradient of matter as observed, for example, in atomistic simulations of hard-core gases. We use path-ensemble theory to…
System size and boundaries determine the patterning dynamics of attracting active particles
Jan Rombouts, Michael L Zhao, Alexander Aulehla +1
Pattern formation often occurs in confined systems, yet how boundaries shape patterning dynamics is unclear. We develop techniques to analyze confinement effects in nonlocal advect…
Repulsive particle interactions enable selective information processing at cellular interfaces
Jenna Elliott, Hiral Shah, Roman Belousov +2
Living systems relay information across membrane interfaces to coordinate compartment functions. We identify a physical mechanism for selective information transmission that arises…
Microcanonical ensemble out of equilibrium
Roman Belousov, Jenna Elliott, Florian Berger +2
Introduced by Boltzmann under the name "monode," the microcanonical ensemble serves as the fundamental representation of equilibrium thermodynamics in statistical mechanics by coun…
Feedback between microscopic activity and macroscopic dynamics drives excitability and oscillations in mechanochemical matter
Tim Dullweber, Roman Belousov, Anna Erzberger
The macroscopic behaviour of active matter arises from nonequilibrium microscopic processes. In soft materials, active stresses typically drive macroscopic shape changes, which in…
Boundary geometry controls a topological defect transition that determines lumen nucleation in embryonic development
Pamela C. Guruciaga, Takafumi Ichikawa, Steffen Plunder +2
Topological defects determine the collective properties of anisotropic materials. How their configurations are controlled is not well understood however, especially in 3D. In livin…
Shape Switching and Tunable Oscillations of Adaptive Droplets
Tim Dullweber, Roman Belousov, Camilla Autorino +2
Living materials adapt their shape to signals from the environment, yet the impact of shape changes on signal processing and associated feedback dynamics remain unclear. We find th…
Poissonian cellular Potts models reveal nonequilibrium kinetics of cell sorting
Roman Belousov, Sabrina Savino, Prachiti Moghe +3
Cellular Potts models are broadly applied across developmental biology and cancer research. We overcome limitations of the traditional approach, which reinterprets a modified Metro…
