Entwined lattice of atoms and anionic electrons in layered electride LaCl
Songyuan Geng, Xin Wang, Jianqi Zhong +14
Controlling the lattice geometry that governs electronic structure is a central theme in condensed-matter physics, yet in crystalline solids this geometry is usually fixed by the a…

YCl Electride as a Multi-Orbital Correlated Topological Dice Lattice System
Jianqi Zhong, Songyuan Geng, Teng-Fei Ying +2
The long-sought dice lattice flat band has recently been discovered for the first time in two-dimensional layered electride yttrium monochloride (YCl) [Nature Communications 17, 22…

Magnons in multiorbital Hubbard models, from Lieb to kagome
Teng-Fei Ying, Hugo U. R. Strand, Benjamin T. Zhou +1
We investigate the magnetic orders and excitations in a half-filled Hubbard model that continuously interpolates between the Lieb and kagome lattices. Using self-consistent Hartree…
