Mathematically, symmetry breaking is easy to … WebSep 22, 2024 · The Goldstone theoremis the short answer. The number of Goldstone bosons is equal to the number of broken generatorsof the continuous symmetry. Your initial symmetry is $U(1)$, which has one generator. Having broken that, since your post-SSB Lagrangian depends on real fields only, you can expect at most one Goldstone mode.

WebSep 21, 2024 · The formulation of the Nambu–Goldstone theorem in the scenario of the non-Hermitian Field theory (respecting the Parity-time reversal (PT) symmetry in order to satisfy unitarity) was done by Alexandre, Ellis, Millingtone and Seynaeve in [14, 15]. In such a case, the authors demonstrated that for every conserved current, there should be a ... WebMar 13, 2014 · In a paper published in Physics Letters on 15 September 1964 (received on 27 July 1964), Peter Higgs showed that Goldstone bosons need not occur when a local symmetry is spontaneously broken in a relativistic theory (1). Instead, the Goldstone mode provides the third polarisation of a massive vector field.
