Spontaneous symmetry breaking in classical systems does mean that the classical ground state (represented by a point in phase space) breaks the symmetry. However, spontaneous …

2020年11月25日 · Spontaneous symmetry breaking is a phenomenon in which the Hamiltonian or Lagrangian of your system has a certain symmetry, but some relevant state of your system …

2016年8月21日 · Spontaneous symmetry breaking is a mode of realization of symmetry breaking in a physical system, where the underlying laws are invariant under asymmetry transformation, …

In short: The spontaneous breaking of global U(1) symmetry, rather than local 'gauge symmetry', gives rise to the non-zero vacuum expectation value of Higgs field. This non-zero VEV is an …

2023年7月16日 · In chapter 19 of An Introduction to Quantum Field Theory by Peskin & Schroeder, they discuss spontaneous symmetry breaking (SSB) at low energies in massless …

Classical Mechanics (CM) exhibits spontaneously symmetry breaking if and only if the system is perturbed. Quantum mechanics (QM) exhibits no symmetry breaking, because the ground …

$\begingroup$ Yeah, I'm not too sure about the solitons, but isn't the idea of spontaneous symmetry breaking for a real scalar field due to the fact that you have a Lagrangian density of …
