We discuss the magnetization M_m in the m-th column of the zig-zag layered 2D Ising model on a half-plane using Kadanoff-Ceva fermions and orthogonal polynomials techniques. Our main result...

The celebrated result by Biane-Bougerol-O'Connell relates Duistermaat-Heckman (DH) measures for coadjoint orbits of a compact Lie group G with the multi-dimensional Pitman transform of the...

We systematically analyse weak coupling limits for 2-form tensor fields in the presence of gravity. Such limits are significant for testing various versions of the Weak Gravity and Swampland...

String theory on {\rm AdS}_3 \times {\rm S}^3 \times {\rm S}^3 \times {\rm S}^1 with pure NS-NS flux and minimal flux through one of the two {\rm S}^3's is studied from a world-sheet perspective...

We construct an explicit equivalence between the (bi)category of gl(2) webs and foams and the Bar-Natan (bi)category of Temperley-Lieb diagrams and cobordisms. With this equivalence we can fix...

We present the first-principle derivation of a weak-strong duality between the fishnet theory in four dimensions and a discretised string-like model living in five dimensions. At strong coupling...

This Astro-2020 White Paper deals with what we might learn from future gravitational wave observations about the early universe phase transitions and their energy scales, primordial black holes...

We compute tautological integrals over Quot schemes on curves and surfaces. After obtaining several explicit formulas over Quot schemes of dimension 0 quotients on curves (and finding a new...

We model the Lights Out game on general simple graphs in the framework of linear algebra over the field \mathbb F_2. Based upon a version of the Fredholm alternative, we introduce a separating...

In this note, we revisit the Θ-invariant as defined by R. Bott and the first author. The Θ-invariant is an invariant of rational homology 3-spheres with acyclic orthogonal local systems, which...

We use the monodromy method to compute expectation values of an arbitrary number of light operators in finitely excited ("heavy") eigenstates of holographic 2D CFT. For eigenstates with scaling...
