Symmetry in nuclear physics and astrophysicsVesić, Jelena (Avtor) symmetry energyisospinnuclear symmetrySymmetry is a key principle in physics that links basic invariances to the structure of matter and the evolution of the universe. In this review, we use symmetry as a unifying thread connecting nuclear structure, nuclear reactions, and dense matter, and we highlight how symmetry-based arguments connect laboratory observables to astrophysical constraints. We present the essential concepts in a form accessible to a broad physics audience.MDPI20262026-03-13 11:30:21Neznano28303Švicasl© 2026 by the author.
