Poking a nanostring: Scientists uncover energy cascades in tiny resonators

Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. For the first time, researchers have observed this cascade reaching all the way up to the fifth mode, while only actuating the first mode.
