Higher-Rank Connections and Deformed Schrödinger Operators
Jonah Baerman, Alba Grassi, Giovanni Ravazzini
We study the connection problem for a class of linear differential equations of order closely related to the Baxter equation of the quantum Toda chain. The space of solutions i…
Eigenfunctions of deformed Schrödinger equations
Matijn François, Alba Grassi, Tommaso Pedroni
We study the spectral problems associated with the finite-difference operators , where is an arbitrary polynomial potential of degree . These…
Large charge meets semiclassics in super Yang-Mills
Augustus Brown, Francesco Galvagno, Alba Grassi +2
We study the large-charge sector of super Yang-Mills theory (SYM) with gauge group by constructing a special class of half-BPS heavy operators, termed "cano…
On the open TS/ST correspondence
Matijn François, Alba Grassi
The topological string/spectral theory correspondence establishes a precise, non-perturbative duality between topological strings on local Calabi-Yau threefolds and the spectral th…
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…
Matrix models for extremal and integrated correlators of higher rank
Alba Grassi, Cristoforo Iossa
We study extremal and integrated correlators of half-BPS operators in four-dimensional SQCD and SYM with gauge group. We focus on the large…
