Visualization of Inertial and Kelvin Waves on the Quantum Vortex Lattice in Superfluid Helium
Florian Lorin, Charles Peretti, Corentin Bourjaillat +3
Superfluid He subjected to steady rotation develops a regular lattice of quantum vortices aligned with the rotation axis. We prepare this lattice in a rotating cryostat, pertur…
