论文摘要
我们在三个维度上研究了大N费米子CFT的大电荷部门。根据固定电荷的模型和性质，我们找到了两种类型的描述：根据超氟或费米球体。我们明确计算固定电荷最低运算符的共形尺寸，在超流体情况下，我们验证了声子频谱的EFT预测。
We study the large-charge sector of large-N fermionic CFTs in three dimensions. Depending on the model and the nature of the fixed charge, we find two types of descriptions: in terms of a superfluid or a Fermi sphere. We explicitly compute the conformal dimensions of the lowest operator of fixed charge and in the superfluid case verify the EFT predictions for the phonon spectrum.
