A Diamond Speck Becomes a Sound Laser ⚡ экспресс
Original: "Autonomous phonon maser in levitated spin-mechanics"
A tiny diamond with an internal defect spontaneously began to vibrate, amplifying its oscillations like a laser for sound.

A tiny diamond dust particle floats in a vacuum and suddenly starts vibrating on its own, like a minuscule bell. Inside it is a defect that, under light and microwaves, turns into a sound amplifier. This 'sound laser' is thousands of times more sensitive than ordinary ones: it can pick up the tremor from a single molecule or a gravitational wave.
🎯 The maser is the older brother of the laser: it was first built in 1954 for microwaves, and now the same principle brings sound vibrations to life in a crystal.
🎬 In science fiction, self-exciting crystals often serve as the heart of detectors and engines.
