1203.1494 (Yoshimasa Hidaka)

Counting rule for Nambu-Goldstone modes in nonrelativistic systems    [PDF]

Yoshimasa Hidaka
The counting rule of Nambu-Goldstone modes is discussed using Mori's projection operator method in nonrelativistic systems. We show the number of the Nambu-Goldstone modes are equal to the number of the broken charges, Q_a, minus half the rank of the expectation value of [Q_a,Q_b], if the corresponding matrix of the decay constant is regular.
