Duality defects in D n -type Niemeier lattice CFTs by Sachin Grover, Subramanya Hegde, Dileep P. Jatkar

“…Abstract We discuss the construction of duality defects in c = 24 meromorphic CFTs that correspond to Niemeier lattices. We will illustrate our constructions for the D n -type lattices. …”

BKM Lie superalgebras from counting twisted CHL dyons – II by Suresh Govindarajan, Sutapa Samanta

“…We show the modularity of some Siegel modular forms that appear in umbral moonshine associated with Niemeier lattices constructed from A-type root systems and further show that the same Siegel modular forms appear for generalized Mathieu moonshine in some cases. …”

A lattice theoretical interpretation of generalized deep holes of the Leech lattice vertex operator algebra by Ching Hung Lam, Masahiko Miyamoto

“…Höhn, which relates the weight one Lie algebras of holomorphic VOAs of central charge $24$ to certain codewords associated with the glue codes of Niemeier lattices.…”
