Dynamics of volcanic vortex rings
Scientific Reports, 2023 Vortex rings can easily be generated in the laboratory or with homemade devices, but they have also been observed on volcanoes, since the eighteenth century. However, the physical conditions under which volcanic vortex rings form are still unknown.

Mutual friction and vortex Hall angle in a strongly interacting Fermi superfluid [PDF]
Nature CommunicationsWe investigate the two-dimensional motion of a single vortex orbiting a pinned anti-vortex in a unitary Fermi superfluid. By analyzing its trajectory, we measure the yet-unknown longitudinal and transverse mutual friction coefficients, which quantify the

Vortex Dynamics in Trabeculated Embryonic Ventricles. [PDF]
J Cardiovasc Dev Dis, 2019 Proper heart morphogenesis requires a delicate balance between hemodynamic forces, myocardial activity, morphogen gradients, and epigenetic signaling, all of which are coupled with genetic regulatory networks. Recently both in vivo and in silico studies have tried to better understand hemodynamics at varying stages of veretebrate cardiogenesis.
