Effective field theory of emergent symmetry breaking in deformed atomic nuclei
Effective field theory of emergent symmetry breaking in deformed atomic nuclei
Spontaneous symmetry breaking in non-relativistic quantum systems has previously been addressed in the framework of effective field theory. Low-lying excitations are constructed from Nambu–Goldstone modes using symmetry arguments only. We extend that approach to finite systems. The approach is very general. To be specific, however, we consider atomic nuclei with …
