Unified low-energy effective Hamiltonian and the band topology of $p$-block square-net layer derivatives

S. I. Hyun, Inho Lee, Geunsik Lee +1

In recent years, low-dimensional materials with tetragonal $P4/nmm$ (orthorhombic $Pnma$) space group having square-net (chain-like) substructure of $p$-block elements have been st…
