In theoretical physics, a bare particle is an excitation of an elementary quantum field.{{Cn|date=August 2024}} In solid-state physics, quasiparticles are dressed particles that also include additional particles surrounding the bare one.{{Cite book |last=Rössler |first=Ulrich |url=https://books.google.com/books?id=Mi3rCAAAQBAJ&dq=%22Bare+particle%22+-wikipedia&pg=PA204 |title=Solid State Theory: An Introduction |date=2013-06-29 |publisher=Springer Science+Business Media |isbn=978-3-662-09940-7 |pages=203 |language=en}}{{Cite book |last=Economou |first=Eleftherios N. |author-link=Eleftherios Economou |url=https://books.google.com/books?id=HdJDAAAAQBAJ&dq=%22Bare+particle%22+-wikipedia&pg=PA276 |title=Green's Functions in Quantum Physics |date=2006-08-02 |publisher=Springer Science+Business Media |isbn=978-3-540-28841-1 |pages=276 |language=en}}
