Exact WKB of solutions by Borel summation and open TBA
Qianyu Hao
In this paper, we study the exact WKB methods for solutions of the Schrödinger equations corresponding to quantum Seiberg-Witten curves in 4d theories with surface…
On quivers, spectral networks and black holes
Paolo Arnaudo, Alba Grassi, Qianyu Hao
It was recently found that connection coefficients of the Heun equation can be derived in closed form using crossing symmetry in two-dimensional Liouville theory via the Nekrasov-S…
A new construction of Virasoro blocks
Qianyu Hao, Andrew Neitzke
We introduce a nonabelianization map for conformal blocks, which relates Virasoro blocks on a Riemann surface to Heisenberg blocks on a branched double cover $\widetilde{…
Connecting topological strings and spectral theory via non-autonomous Toda equations
Pavlo Gavrylenko, Alba Grassi, Qianyu Hao
We consider the Topological String/Spectral theory duality on toric Calabi-Yau threefolds obtained from the resolution of the cone over the singularity. Assuming Kyiv for…
Exponential Networks, WKB and Topological String
Alba Grassi, Qianyu Hao, Andrew Neitzke
We propose a connection between 3d-5d exponential networks and exact WKB for difference equations associated to five dimensional Seiberg-Witten curves, or equivalently, to quantum…
Exact WKB methods in
Alba Grassi, Qianyu Hao, Andrew Neitzke
We study in detail the Schrödinger equation corresponding to the four dimensional SQCD theory with one flavour. We calculate the Voros symbols, or quantum p…
Factorized class theories and surface defects
Behzat Ergun, Qianyu Hao, Andrew Neitzke +1
It is known that some theories of class are actually factorized into multiple decoupled nontrivial four-dimensional theories. We propose a way of constructing examples of…
BPS states in the Minahan-Nemeschansky theory
Qianyu Hao, Lotte Hollands, Andrew Neitzke
We use the method of spectral networks to calculate BPS degeneracies in the Minahan-Nemeschansky theory, as representations of the flavor symmetry. Our results provide…
