These so-called bound states in the continuum (BIC) are like whirlpools that remain in place even as a river flows around them. But for decades, scientists believed this phenomenon could not exist in a compact, single-particle system.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A joint research team has successfully demonstrated the complete confinement of mechanical waves within a single resonator\u2014something long thought to be theoretically impossible.
