Passive polymers in active turbulence undergo a collapse-stretch transition
Zahra K. Valei, Davide Marenduzzo, Tyler N. Shendruk
Active processes in living systems generate nonequilibrium forces that deform embedded passive macromolecules. To understand how such dynamics influence polymer conformation, we st…
Scaling laws for passive polymer dynamics in active turbulence
Zahra K. Valei, Tyler N. Shendruk
Biological systems commonly combine intrinsically out-of-equilibrium active components with passive polymeric inclusions to produce unique material properties. To explore these com…
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…
Active nematics in corrugated channels
Jaideep P. Vaidya, Tyler N. Shendruk, Sumesh P. Thampi
Active nematic fluids exhibit complex dynamics in both bulk and in simple confining geometries. However, complex confining geometries could have substantial impact on active sponta…
Dynamics of polymers in coarse-grained nematic solvents

Liquid crystalline media mediate interactions between suspended particles and confining geometries, which not only has potential to guide patterning and bottom-up colloidal assembl…
3D active nematic disclinations behave as Majorana quasiparticles
Louise C. Head, Giuseppe Negro, Livio N. Carenza +7
Quasiparticles are low-energy excitations with important roles in condensed matter physics. An intriguing example is provided by Majorana fermions, quasiparticles which are identic…

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…
Active Darcy's Law
Ryan R. Keogh, Timofey Kozhukhov, Kristian Thijssen +1
While bacterial swarms can exhibit active turbulence in vacant spaces, they naturally inhabit crowded environments. We numerically show that driving disorderly active fluids throug…
Spontaneous Self-Constraint in Active Nematic Flows
Louise C. Head, Claire Dore, Ryan Keogh +5
Active processes drive and guide biological dynamics across scales -- from subcellular cytoskeletal remodelling, through tissue development in embryogenesis, to population-level ba…
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"…
Smectic Layering: Landau theory for a complex-tensor order parameter
Jack Paget, Una Alberti, Marco G. Mazza +2
Composed of microscopic layers that stack along one direction while maintaining fluid-like positional disorder within layers, smectics are excellent systems for exploring topology,…
