Physicists Find Useful Energy Hiding in Quantum “Waste Heat”
An atom in a cavity between two mirrors (left) acts as a heat engine in a driven-dissipative quantum…
Rice University physicists used a grain-of-sand-sized magnet levitated above a superconductor cooled to near absolute zero to search for ultraheavy dark matter. Results presented in September 2026 found no signal but probed particles approximately 10 million times heavier than those examined in previous levitated-particle experiments.
A tiny magnet floating above a superconductor has given physicists a way to test an unusually heavy set…
In 2026, physicists allowed an Alcubierre-shaped warp field to evolve instead of holding its bubble profile artificially fixed, and found that it became unstable: nearby trajectories crossed to form caustics, making the velocity field multivalued unless some still-unknown physics could stabilize it.
A warp bubble can look orderly when its shape is prescribed in advance. A 2026 study asked what…
Balancing an egg: How scientists built a floating magnet to hunt dark matter
A magnet the thickness of a few sheets of paper floats in mid-air with essentially no friction. It…
Physicists Devise New Way to Listen for ‘Hairy’ Black Holes
When two black holes merge, the resulting object rings like a struck bell, radiating gravitational waves that fade…
