    • note
    • 4-term in evaluating the energy spectrum from Eq. (15). However, such a quartic term could be eliminated in comparison with quadratic terms since we are considering the lowest energy excitations. Thus, we would still have a linear spectrum and would derive the same power counting rule as (21). However, the rule would tell us that we do not need include any derivatives of σ from the beginning at all.
