It's solid-state physics - there is pretty crazy stuff possible by coupling/decoupling or increasing/decreasing properties (e.g. mass, charge, spin) of particles that we otherwise think of as being "elementary". Have a look here for a list of different quasiparticles, as they are called: https://en.wikipedia.org/wiki/List_of_quasiparticles https://en.wikipedia.org/wiki/List_of_quasiparticles Follow some of the links there, as it is only going to get crazier. This one, for example, sounds more like technobabble from your favourite scifi-show than actual science: https://en.wikipedia.org/wiki/Intersubband_polariton https://en.wikipedia.org/wiki/Intersubband_polariton
