Researchers have innovated a microscopic "trampoline" – a sophisticated phonon waveguide crafted from an ultra-thin silicon nitride film. The waveguide's surface design is rooted in mathematical topology principles, enabling it to steer phonons around corners with exceptionally low loss, even navigating sharp 120-degree turns with minimal momentum dissipation. This groundbreaking development holds promise for significantly enhancing signal transmission efficiency within microchips.
