Imaginary particles. Explaining tangible things…
Tangible products—like a solar-powered hearing aid—may come from not-so-real particles. More particular, scientists analyze the behaviour of modern materials with the help of imaginary structures called quasiparticles. (1) In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if…
