3d宇称违反CFTs的大电荷区

Large Charge Sector of 3d Parity-Violating CFTs

Gabriel Cuomo, Luca V. Delacretaz, Umang Mehta

摘要:

某些具有整体$U(1)$对称性的CFTs在与化学势耦合时成为超流体。当这种情况发生时,戈德斯通的有效场论控制了最轻的大电荷算符的光谱和跃迁。我们表明,在3d中,这个EFT包含一个单一的奇偶违反1-导数项与量化系数。这一项迫使超流的基态在球体上产生涡旋,从而产生比宇称不变的CFTs更丰富的大电荷算符谱。我们测试我们的预测在弱耦合陈-西蒙斯物质理论。

英文摘要:

Certain CFTs with a global $U(1)$ symmetry become superfluids when coupled to a chemical potential. When this happens, a Goldstone effective field theory controls the spectrum and correlators of the lightest large charge operators. We show that in 3d, this EFT contains a single parity-violating 1-derivative term with quantized coefficient. This term forces the superfluid ground state to have vortices on the sphere, leading to a spectrum of large charge operators that is remarkably richer than in parity-invariant CFTs. We test our predictions in a weakly coupled Chern-Simons matter theory.
