Large-$S$ limit of the large-$N$ theory for the triangular antiferromagnet

Shang-Shun Zhang, E. A. Ghioldi, Yoshitomo Kamiya +3

Large-$S$ and large-$N$ theories (spin value $S$ and spinor component number $N$) are complementary, and sometimes conflicting, approaches to quantum magnetism. While large-$S$ spi…
