Topological kicks enhance colloidal diffusivity in topological turbulence
Timofey Kozhukhov, Benjamin Loewe, Kristian Thijssen +1
Colloidal inclusions in nematic fluids induce topological defects that govern their dynamics. These defects create well-understood rheological behavior in passive nematics, but the…
Multi-Particle Collision Framework for Active Polar Fluids
Oleksandr Baziei, Benjamín Loewe, Tyler N. Shendruk
Sufficiently dense intrinsically out-of-equilibrium suspensions, such as those observed in biological systems, can be modelled as active fluids characterised by their orientational…
Multiphase Field Model of Cells on a Substrate: From 3D to 2D
Michael Chiang, Austin Hopkins, Benjamin Loewe +2
Multiphase field models have emerged as an important computational tool for understanding biological tissue while resolving single-cell properties. While they have successfully rep…
Mitigating Density Fluctuations in Particle-based Active Nematic Simulations
Timofey Kozhukhov, Benjamin Loewe, Tyler N. Shendruk
Understanding active matter has led to new perspectives on biophysics and non-equilibrium dynamics. However, the development of numerical tools for simulating active fluids capable…
Intercellular Friction and Motility Drive Orientational Order in Cell Monolayers
Michael Chiang, Austin Hopkins, Benjamin Loewe +2
Spatiotemporal patterns in multicellular systems are important to understanding tissue dynamics, for instance, during embryonic development and disease. Here, we use a multiphase f…
Motility induced phase separation of deformable cells
Austin Hopkins, Benjamin Loewe, Michael Chiang +2
Using a multi-phase field model, we examine how particle deformability, which is a proxy for cell stiffness, affects motility induced phase separation (MIPS). We show that purely r…
Anisotropic run-and-tumble-turn dynamics
Benjamin Loewe, Tyler N. Shendruk
Run-and-tumble processes successfully model several living systems. While studies have typically focused on particles with isotropic tumbles, recent examples exhibit "tumble-turns"…
Yield Stress and Compliance in Active Cell Monolayers
Austin Hopkins, Michael Chiang, Benjamin Loewe +2
The rheology of biological tissue plays an important role in many processes, from organ formation to cancer invasion. Here, we use a multi-phase field model of motile cells to simu…
Helical Flow States in Active Nematics
Ryan Keogh, Santhan Chandragiri, Benjamin Loewe +3
We show that confining extensile nematics in 3D channels leads to the emergence of two self-organized flow states with nonzero helicity. The first is a pair of braided anti-paralle…
Passive Janus Particles Are Self-propelled in Active Nematics
Benjamin Loewe, Tyler N. Shendruk
While active systems possess notable potential to form the foundation of new classes of autonomous materials, designing systems that can extract functional work from active surroun…
Shape and size changes of adherent elastic epithelia
Benjamin Loewe, Francesco Serafin, Suraj Shankar +2
Epithelial tissues play a fundamental role in various morphogenetic events during development and early embryogenesis. Although epithelial monolayers are often modeled as two-dimen…
Solid-Liquid Transition of Deformable and Overlapping Active Particles
Benjamin Loewe, Michael Chiang, Davide Marenduzzo +1
Experiments and theory have shown that cell monolayers and epithelial tissues exhibit solid-liquid and glass-liquid transitions. These transitions are biologically relevant to our…
Flocking from a quantum analogy: Spin-orbit coupling in an active fluid
Benjamin Loewe, Anton Souslov, Paul M. Goldbart
Systems composed of strongly interacting self-propelled particles can form a spontaneously flowing polar active fluid. The study of the connection between the microscopic dynamics…
Emergent tilt order in Dirac polymer liquids
Anton Souslov, Benjamin Loewe, Paul M. Goldbart
We study a liquid of zigzagging two-dimensional directed polymers with bending rigidity, i.e., polymers whose conformations follow checkerboard paths. In the continuum limit the st…
