Topological defects lead to energy transfer in active nematics
Daniel J. G. Pearce, Berta MartÃnez-Prat, Jordi Ignés-Mullol +1
Active nematics are fluids in which the components have nematic symmetry and are driven out of equilibrium due to the microscopic generation of an active stress. When the active st…

Active nematic pumps
Ignasi Vélez-Ceron, Rodrigo C. V. Coelho, Pau Guillamat +4
Microfluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from…

Beyond Dipolar Activity: Quadrupolar Stress Drives Collapse of Nematic Order on Frictional Substrates
Aleksandra Ardaševa, Ignasi Vélez-Cerón, Martin Cramer Pedersen +3
The field of active nematics has traditionally employed descriptions based on dipolar activity, with interactions that align along a single axis. However, it has been theoretically…
