Description:
Author(s): Rong Yu and Qimiao Si Motivated by the properties of the iron chalcogenides, we study the phase diagram of a generalized Heisenberg model with frustrated bilinear-biquadratic interactions on a square lattice. We identify zero-temperature phases with antiferroquadrupolar and Ising-nematic orders. The effects of quantum fl… [Phys. Rev. Lett. 115, 116401] Published Tue Sep 08, 2015
