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…
