Is it true that Gapless excitations in condensed matter physics include Goldstone bosons resulting from spontaneous symmetry breaking?

Yes. Gapless excitations in condensed matter and quantum many-body systems are well established as arising from spontaneous symmetry breaking in the form of Goldstone bosons.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The retrieved papers provide robust theoretical and experimental evidence demonstrating that spontaneous symmetry breaking in condensed matter and quantum many-body systems results in gapless excitations, specifically Nambu-Goldstone bosons. Papers [0], [1], and [8] directly support this fundamental principle.
