Gravitational algebras and applications to nonequilibrium physics

Michele Cirafici

This note aims to offer a non-technical and self-contained introduction to gravitational algebras and their applications in the nonequilibrium physics of gravitational systems. We…

On the Nonequilibrium Dynamics of Gravitational Algebras

Michele Cirafici

We explore nonequilibrium features of certain operator algebras which appear in quantum gravity. The algebra of observables in a black hole background is a Type $\mathrm{II}_\infty…

$t t^{*}$ Toda equations for surface defects in $N = 2$ SYM and instanton counting for classical Lie groups

Giulio Bonelli, Fran Globlek, Alessandro Tanzini

The partition function of $N = 2$ super Yang-Mills theories with arbitrary simple gauge group coupled to a self-dual $Ω$ -background is shown to be fully determined by study…

M2-branes and $q$ -Painlevé equations

Giulio Bonelli, Fran Globlek, Naotaka Kubo +2

In this paper we investigate a novel connection between the effective theory of M2-branes on $(C^{2} / Z_{2} \times C^{2} / Z_{2}) / Z_{k}$ and the $\ma…

Irregular Liouville correlators and connection formulae for Heun functions

Giulio Bonelli, Cristoforo Iossa, Daniel Panea Lichtig +1

We perform a detailed study of a class of irregular correlators in Liouville Conformal Field Theory, of the related Virasoro conformal blocks with irregular singularities and of th…

Instantons to the people: the power of one-form symmetries

Giulio Bonelli, Fran Globlek, Alessandro Tanzini

We show that the non-perturbative dynamics of $N = 2$ super Yang-Mills theories in a self-dual $Ω$ -background and with an arbitrary simple gauge group is fully determined b…

ADHM in 8d, coloured solid partitions and Donaldson-Thomas invariants on orbifolds

Giulio Bonelli, Nadir Fasola, Alessandro Tanzini +1

We study the moduli space of $S U (4)$ invariant BPS conditions in supersymmetric gauge theory on non-commutative $C^{4}$ by means of an ADHM-like quiver construction and we…

A note on discrete dynamical systems in theories of class $S$

Michele Cirafici

In this note we consider the set of line operators in theories of class $S$ . We show that this set carries the action of a natural discrete dynamical system associated with the BPS…

BPS quivers of five-dimensional SCFTs, Topological Strings and q-Painlevé equations

Giulio Bonelli, Fabrizio Del Monte, Alessandro Tanzini

We study the discrete flows generated by the symmetry group of the BPS quivers for Calabi-Yau geometries describing five dimensional superconformal quantum field theories on a circ…

Circular quiver gauge theories, isomonodromic deformations and $W_{N}$ fermions on the torus

Giulio Bonelli, Fabrizio Del Monte, Pavlo Gavrylenko +1

We study the relation between class S theories on punctured tori and isomonodromic deformations of flat SL(N) connections on the two dimensional torus with punctures. Turning on th…

Crepant Resolutions of $C^{3} / Z_{4}$ and the Generalized Kronheimer Construction (in view of the Gauge/Gravity Correspondence)

Ugo Bruzzo, Annamaria Fino, Pietro Fré +2

As a continuation of a general program started in two previous publications, in the present paper we study the Kähler quotient resolution of the orbifold $\mathbb{C}^3/\mathbb{Z}_4…

$N = 2^{*}$ gauge theory, free fermions on the torus and Painlevé VI

Giulio Bonelli, Fabrizio Del Monte, Pavlo Gavrylenko +1

In this paper we study the extension of Painlevé/gauge theory correspondence to circular quivers by focusing on the special case of $S U (2)$ $N = 2^{*}$ theory. We show that t…
