Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

Complex plasmas, including dusty plasmas, represent an enthralling state of matter where micron‐sized particles are immersed within an ionised gas. In these systems, the charged microparticles ...
