Extreme topological tunability of Weyl-Kondo semimetal to Zeeman coupling
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
There is considerable interest in the intersection of correlations and topology, especially in metallic systems. Among the outstanding questions are how strong correlations drive n…
Weyl-Kondo Semimetal: Towards Control of Weyl Nodes
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
Heavy fermion semimetals represent a promising setting to explore topological metals driven by strong correlations. In this paper, we i) summarize the theoretical results in a Weyl…
Density Matrix Renormalization Group Study of Nematicity in Two Dimensions: Application to a Spin- Bilinear-Biquadratic Model on the Square Lattice
Wen-Jun Hu, Shou-Shu Gong, Hsin-Hua Lai +2
Nematic order is an exotic property observed in several strongly correlated systems, such as the iron-based superconductors. Using large-scale density matrix renormalization group…
Weyl-Kondo semimetals in nonsymmorphic systems
Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen +1
There is considerable current interest to explore electronic topology in strongly correlated metals, with heavy fermion systems providing a promising setting. Recently, a Weyl-Kond…
Plaquette instability competing with bicollinear ground state in detwinned FeTe
David W. Tam, Hsin-Hua Lai, Jin Hu +10
We use inelastic neutron scattering to show that long-range spin waves arising from the static bicollinear antiferromagnetic (AF) order in FeTe, which have twofold rotational symme…
Nematic and Antiferromagnetic Quantum Criticality in a Multi-Orbital Hubbard Model for Iron Pnictides
Wen-Jun Hu, Haoyu Hu, Rong Yu +4
The extent to which quantum criticality drives the physics of iron pnictides is a central question in the field. Earlier theoretical considerations were based on an effective field…
