Students from the Superconductivity Group School of Physics and Astronomy at Tel-Aviv University recently demonstrated quantum levitation.
Quantum levitation can happen when you manipulate the Casimir force -- the force of the quantum vacuum -- by introducing other materials like liquid to change the force from attraction to repulsion.
The experiment shows a superconducting magnet, which is frozen in liquid nitrogen, locked in space. The superconductor pivots around the axis of the magnet in a three-dimensional field.
LAUNCH has contacted the team and will update this story if we receive a response.
When placed slightly above a magnetic track, the superconductor follows the path, resembling a hovering disc.
The group, led by Professor Guy Deutscher, comprises three PhD students, two MSc students and one technician.
The superconductor floats on top of the magnet.
The superconductor follows the path of the magnets, staying suspended in the air.
