Fully developed active turbulence defined through a non-equilibrium phase transition
Lasse Bonn, Tianxiang Ma, Olga Bantysh +7
Non-equilibrium systems challenge the standard definitions of phases and phase transitions from equilibrium statistical physics. For example, in active fluids continuous energy inj…
Cell division sets a universal flow geometry in cell layers
Tianxiang Ma, Lasse Bonn, Valeriia Grudtsyna +4
Collective flows in epithelial tissues contain a geometric backbone of vortical interfaces whose statistics exhibit hallmarks of critical percolation and conformal invariance. Yet…
Epithelia Realize Nematopolar Topological Defect Structures
Tianxiang Ma, Niels de Graaf Sousa, Valeriia Grudtsyna +2
We introduce a shape-based polar order parameter that captures the structural asymmetry of cells within epithelial monolayers. By combining bright-field imaging and traction force…
Anti-hyperuniform Critical States of Active Topological Defects
Simon Guldager Andersen, Tianxiang Ma, Makito F. Katsume +4
Topological defects are fundamental to the collective dynamics of non-equilibrium systems and in active matter, mediating spontaneous flows, dynamic self-organization, and emergent…
Density-Velocity Relation Is Scale-Dependent in Epithelial Monolayers
Hengdong Lu, Tianxiang Ma, Amin Doostmohammadi
The relationship between cell density and velocity is often assumed to be negative, reflecting crowding-induced suppression of movement. However, observations across systems reveal…
Cellular Flow Architecture Exposes the Hidden Mechanics of Biological Matter
Tianxiang Ma, Valeriia Grudtsyna, Robin V. Bölsterli +1
Understanding how biomechanical reorganization governs key biological processes, such as morphogenesis and development, requires predictive insights into stress distributions and c…
