Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic symmetry can cancel energy loss.
Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, ...
Rotational symmetry-broken mechanism for simplifying exceptional point achievement. (a) 3D model of waveguide coupled RTR. (b) Field distribution and (c) far-field pattern of RTR at EP. The spectral ...

Scientific sorcery? Japan achieves near-frictionless levitation on macroscopic rotor
The new levitating rotor works because of its rotational symmetry. Unlike plates that move up and down in varying magnetic fields, the spinning rotor stays within a constant magnetic flux. This ...
In the coming weeks, Symmetry will explore the ways scientists are using artificial intelligence to advance particle physics and astrophysics—in a series of articles written and illustrated entirely ...
