Crystal Melting and Toric Calabi-Yau Manifolds
Hirosi Ooguri, Masahito Yamazaki
We construct a statistical model of crystal melting to count BPS bound states of D0 and D2 branes on a single D6 brane wrapping an arbitrary toric Calabi-Yau threefold. The three-d…
Octonions, G_2 and generalized Lie 3-algebras
Masahito Yamazaki
We construct an explicit example of a generalized Lie 3-algebra from the octonions. In combination with the result of arXiv:0807.0808, this gives rise to a three-dimensional N=2 Ch…
Toric Calabi-Yau four-folds dual to Chern-Simons-matter theories
Kazushi Ueda, Masahito Yamazaki
We propose a new method to find gravity duals to a large class of three-dimensional Chern-Simons-matter theories, using techniques from dimer models. The gravity dual is given by M…
Intersecting Solitons, Amoeba and Tropical Geometry
Toshiaki Fujimori, Muneto Nitta, Kazutoshi Ohta +2
We study generic intersection (or web) of vortices with instantons inside, which is a 1/4 BPS state in the Higgs phase of five-dimensional N=1 supersymmetric U(Nc) gauge theory on…
New Aspects of Heterotic--F Theory Duality
Hirotaka Hayashi, Radu Tatar, Yukinobu Toda +2
In order to understand both up-type and down-type Yukawa couplings, F-theory is a better framework than the perturbative Type IIB string theory. The duality between the Heterotic a…
Anomalies and O-plane charges in orientifolded brane tilings
Yosuke Imamura, Keisuke Kimura, Masahito Yamazaki
We investigate orientifold of brane tilings. We clarify how the cancellations of gauge anomaly and Witten's anomaly are guaranteed by the conservation of the D5-brane charge. We al…
