Quantum modularity in refined topological recursion

Veronica Fantini, Kento Osuga

In this paper we study the Borel summability and quantum modularity of the free energy computed by refined topological recursion on the Weber-type refined spectral curve. On the on…

Superconformal topological recursion

Nezhla Aghaei, Reinier Kramer, Nicolas Orantin +1

We investigate a supersymmetric generalisation of topological recursion from two perspectives: algebraic and geometric. The algebraic side concerns a recursive structure encoded in…

Refined BPS structures and topological recursion - the Weber and Whittaker curves

Omar Kidwai, Kento Osuga

We study properties of the recently established refined topological recursion for some simple spectral curves associated to quadratic differentials. We prove explicit formulas for…

Deformation and quantisation condition of the -top recursion

Kento Osuga

We consider a deformation of a family of hyperelliptic refined spectral curves and investigate how deformation effects appear in the hyperelliptic refined topological recursion as…

Refined topological recursion revisited -- properties and conjectures

Kento Osuga

For any (possibly singular) hyperelliptic curve, we give the definition of a hyperelliptic refined spectral curve and the hyperelliptic refined topological recursion, generalising…

Quantum curves from refined topological recursion: the genus 0 case

Omar Kidwai, Kento Osuga

We formulate geometrically (without reference to physical models) a refined topological recursion applicable to genus zero curves of degree two, inspired by Chekhov-Eynard and Marc…

Five-dimensional gauge theories and the local B-model

Andrea Brini, Kento Osuga

We propose an effective framework for computing the prepotential of the topological B-model on a class of local Calabi--Yau geometries related to the circle compactification of fiv…

Super Topological Recursion and Gaiotto Vectors For Superconformal Blocks

Kento Osuga

We investigate a relation between the super topological recursion and Gaiotto vectors for superconformal blocks. Concretely, we introduce the notion of the untwiste…

Topological Recursion in The Ramond Sector

Kento Osuga

We investigate supereigenvalue models in the Ramond sector and their recursive structure. We prove that the free energy truncates at quadratic order in Grassmann coupling constants…

Super Quantum Airy Structures

Vincent Bouchard, Paweł Ciosmak, Leszek Hadasz +3

We introduce super quantum Airy structures, which provide a supersymmetric generalization of quantum Airy structures. We prove that to a given super quantum Airy structure one can…

Harmony for 2-Qubit Entanglement

Kento Osuga, Don N. Page

In this Letter we present a new quantity that shows whether two general qubit systems are entangled, which we call harmony. It captures the notion of separability and maximal entan…

Supereigenvalue Models and Topological Recursion

Vincent Bouchard, Kento Osuga

We show that the Eynard-Orantin topological recursion, in conjunction with simple auxiliary equations, can be used to calculate all correlation functions of supereigenvalue models.

Qubit Transport Model for Unitary Black Hole Evaporation without Firewalls

Kento Osuga, Don N. Page

We give an explicit toy qubit transport model for transferring information from the gravitational field of a black hole to the Hawking radiation by a continuous unitary transformat…

A New Way to Derive the Taub-NUT Metric with Positive Cosmological Constant

Kento Osuga, Don N. Page

We investigate a biaxial Bianchi IX model with positive cosmological constant, which is sometimes called the Lambda-Taub-NUT spacetime, whose exact solution is well known. The mini…
