  "id": "MLC-T-CHM-009774",
  "term": "Quasiparticle",
  "field": "Chemistry",
  "definition": "An emergent excitation of a many-body system that behaves like a particle, with its own effective mass, momentum, energy and mobility, although it cannot exist outside the system that hosts it. Examples in polymers are polarons, which are charges dressed by a surrounding lattice distortion, and excitons, which are bound electron-hole pairs.",
