Two-dimensional long-range uniaxial order in three-dimensional active fluids
A Maitra - Nature Physics, 2023 - nature.com
Elongated active units cannot spontaneously break rotation symmetry in bulk fluids to form
nematic or polar phases. This has led to the image of active suspensions as spontaneously …
