Strongly frustrated 2D magnetism in a 3D hexagonal perovskite
Bocheng Yu, Otkur Omar, Songtai Lv +12
Exotic quantum phenomena are often found to occur in spin systems that exhibit low-dimensional magnetism. By combining nuclear magnetic resonance, neutron scattering, and muon-spin…

Magnetic materials with highly anisotropic chemical bonding can be exfoliated to realize ultrathin sheets or interfaces with highly controllable optical or spintronics responses, w…
Line-Graph Approach to Spiral Spin Liquids
Shang Gao, Ganesh Pokharel, Andrew F. May +8
Competition among exchange interactions is able to induce novel spin correlations on a bipartite lattice without geometrical frustration. A prototype example is the spiral spin liq…

Charge density waves (CDW) are modulations of the electron density and the atomic lattice that develop in some crystalline materials at low temperature. We report an unusual exampl…
Hierarchical excitations from correlated spin tetrahedra on the breathing pyrochlore lattice
Shang Gao, Andrew F. May, Mao-Hua Du +10
The hierarchy of the coupling strengths in a physical system often engenders an effective model at low energies where the decoupled high-energy modes are integrated out. Here, usin…
