Researchers at OIST successfully moved a levitating, centimeter-wide diamond using the force generated by electron spin alone, directly observing a quantum effect on an object subject to gravity. This achievement sets a new baseline for studying the boundary between classical and quantum physics.
Researchers at Kyoto University developed a hybrid graphite-based substance with aligned particles that demonstrates stable diamagnetic levitation. The team successfully created the substance by aligning micro-crystals in a uniform direction and applying a magnetic field, resulting in a miniature flying carpet-like effect.
A macroscopic device has been designed to reduce eddy-current damping, allowing for precise measurements of physical phenomena like gravity. The system uses a graphite disk and rare earth magnets, enabling ultra-precise sensors that can be used in classical and quantum physics research.
Scientists have made a breakthrough in fulfilling perfect diamagnetism of sulfur hydride system under high pressure, using a highly sensitive magnetic susceptibility technique. The research confirms high-temperature superconductivity and determines the superconducting phase diagram of sulfur hydrogen system.
