Frustrated magnetism and bicollinear antiferromagnetic order in FeTe
Hsin-Hua Lai, Shou-Shu Gong, Wen-Jun Hu +1
Iron chalcogenides display a rich variety of electronic orders in their phase diagram. A particularly enigmatic case is FeTe, a metal which possesses co-existing hole and electron…
Unified Spin Model for Magnetic Excitations in Iron Chalcogenides
Patricia Bilbao Ergueta, Wen-Jun Hu, Andriy H. Nevidomskyy
Recent inelastic neutron scattering (INS) measurements on FeSe and Fe(TeSe), have sparked intense debate over the nature of the ground state in these materials. Here we…
Quantum Transitions of Nematic Phases in a Spin- Bilinear-Biquadratic Model and Their Implications for FeSe
Wen-Jun Hu, Hsin-Hua Lai, Shou-Shu Gong +3
Since its discovery, iron-based superconductivity has been known to develop near an antiferromagnetic order, but this paradigm fails in the iron chalcogenide FeSe, whose single-lay…
Variational Monte Carlo study of chiral spin liquid in quantum antiferromagnet on the triangular lattice
Wen-Jun Hu, Shou-Shu Gong, D. N. Sheng
By using Gutzwiller projected fermionic wave functions and variational Monte Carlo technique, we study the spin- Heisenberg model with the first-neighbor (), second-neigh…
Antiferroquadrupolar order and rotational symmetry breaking in a generalized bilinear-biquadratic model on a square lattice
Hsin-Hua Lai, Wen-Jun Hu, Emilian M. Nica +2
The magnetic and nematic properties of the iron chalcogenides have recently been the subject of intense interest. Motivated by the proposed antiferroquadrupolar and Ising-nematic o…
Spin Ferroquadrupolar Order in the Nematic Phase of FeSe
Zhentao Wang, Wen-Jun Hu, Andriy H. Nevidomskyy
We provide evidence that spin ferroquadrupolar (FQ) order is the likely ground state in the nonmagnetic nematic phase of stoichiometric FeSe. By studying the variational mean-field…
Spin liquid nature in the Heisenberg - triangular antiferromagnet
Yasir Iqbal, Wen-Jun Hu, Ronny Thomale +2
We investigate the spin- Heisenberg model on the triangular lattice in the presence of nearest-neighbor and next-nearest-neighbor antiferromagnetic couplin…
