Quiver BPS Indices from Crystal Profiles
Jiakang Bao, Masahito Yamazaki
We derive new exact formulae for elliptic genera in two spacetime dimensions with supercharges, as well as their one- and zero-dimensional counterparts (for Witt…

The Origin of Calabi-Yau Crystals in BPS States Counting
Jiakang Bao, Rak-Kyeong Seong, Masahito Yamazaki
We study the counting problem of BPS D-branes wrapping holomorphic cycles of a general toric Calabi-Yau manifold. We evaluate the Jeffrey-Kirwan residues for the flavoured Witten i…

Crystals and Double Quiver Algebras from Jeffrey-Kirwan Residues
Jiakang Bao, Masahito Yamazaki
We construct statistical mechanical models of crystal melting describing the flavoured Witten indices of supersymmetric quiver gauge theories. Our results can be…
