Counting Nambu-Goldstone modes of higher-form global symmetries

Published 31 Jul 2020 in hep-th, cond-mat.str-el, hep-ph, and nucl-th | (2007.15901v1)

Abstract: We discuss the counting of Nambu-Goldstone (NG) modes associated with the spontaneous breaking of higher-form global symmetries. Effective field theories of NG modes are developed based on symmetry breaking patterns, using a generalized coset construction for higher-form symmetries. We derive a formula of the number of gapless NG modes, which involves expectation values of the commutators of conserved charges, possibly of different degrees.
