RIKEN Lunch Seminar
"Generalized Nambu-Goldstone theorem"
Presented by Yoshimasa Hidaka, RIKEN

Symmetry and its spontaneous breaking are of basic importance
for understanding the low energy physics in many-body systems. When a
continuum symmetry is spontaneously broken, there exist a zero mode
called Nambu-Goldstone (NG) mode, which is well developed in Lorentz
invariant systems. In contrast, in non-Lorentz invariant systems, the
NG theorem has not been well developed. In this talk, we discuss the
recent progress in generalization of NG theorem in non-relativistic systems,
open systems, and systems with higher form symmetries.
