Scientists discover strange “narwhal” waves that trap light beyond known limits

Scientists at Peking University have discovered a new class of electromagnetic waves called "narwhal-shaped wavefunctions" that can trap light at incredibly small scales without generating heat. Unlike previous methods that used metals, this approach uses lossless dielectric materials, avoiding energy waste. The breakthrough enabled a microscope with λ/1000 resolution and could transform quantum optics, super-resolution imaging, and ultra-efficient photonic computing.
