摘要
我们报告了关于最近提出的 3D SCFT 中 F 极大化原理的初步结果。我们在大 N 极限下数值计算了具有单个伴随手征超场的 N=2 Chern-Simons-Matter 理论的三球自由能，已知该理论会展现出与触及幺正界并变为自由场的手征超场相关的偶然对称性模式。我们观察到，F 极大化原理产生了一个与先前获得的界一致的 U(1) R 对称性，但与假设的类 Seiberg 对偶性不一致。与退耦场相关的该原理的潜在修正似乎不足以解释观察到的破坏。

备注
17 pages, 3 figures; v2 a reference has been added, a missing factor of 2 has been corrected in eq (3.3) and the numerical results have been accordingly updated. The new results do not show any obvious signs of violation of previously obtained bounds. A potential disagreement with a postulated Seiberg-like duality is noted
