Superconformal Block Quivers, Duality Trees and Diophantine Equations
Amihay Hanany, Yang-Hui He, Chuang Sun +1
We generalize previous results on N=1, (3+1)-dimensional superconformal block quiver gauge theories. It is known that the necessary conditions for a theory to be superconformal, i.…
Numerical Analyses on Moduli Space of Vacua
Jonathan Hauenstein, Yang-Hui He, Dhagash Mehta
We propose a new computational method to understand the vacuum moduli space of (supersymmetric) field theories. By combining numerical algebraic geometry (NAG) and elimination theo…
Quiver Structure of Heterotic Moduli
Yang-Hui He, Seung-Joo Lee
We analyse the vector bundle moduli arising from generic heterotic compactifications from the point of view of quiver representations. Phenomena such as stability walls, crossing b…
Calabi-Yau Manifolds with Large Volume Vacua
James Gray, Yang-Hui He, Vishnu Jejjala +3
We describe an efficient, construction independent, algorithmic test to determine whether Calabi--Yau threefolds admit a structure compatible with the Large Volume moduli stabiliza…
Hamiltonian description of singular Lagrangian systems with spontaneously broken time translation symmetry
Liu Zhao, Pengfei Yu, Wei Xu
Shapere and Wilczek recently found some singular Lagrangian systems which spontaneously breaks time translation symmetry. The common feature of their models is that the energy func…
Brane Geometry and Dimer Models
Yang-Hui He, Vishnu Jejjala, Diego Rodriguez-Gomez
The field content and interactions of almost all known gauge theories in AdS_5/CFT_4 can be expressed in terms of dimer models or bipartite graphs drawn on a torus. Associated with…
