Integrable auxiliary field deformations of coset models

Autor: Cesàro, Mattia, Kleinschmidt, Axel, Osten, David

We prove the existence of a family of integrable deformations of $\mathbb{Z}_N$-coset models in two dimensions. Our approach uses and generalises the method of auxiliary fields that was recently introduced for the principal chiral model by Ferko and

Abstract We prove the existence of a family of integrable deformations of ℤ N -coset models in two dimensions. Our approach uses and generalises the method of auxiliary fields that was recently introduced for the principal chiral model by Ferko and

A Positive Energy Theorem for AdS Solitons

Autor: Anabalón, Andrés, Cesàro, Mattia, Gallerati, Antonio, Giambrone, Alfredo, Trigiante, Mario

The uncharged AdS$_4$ soliton has been recently shown to be continuously connected to a magnetic, supersymmetric AdS$_4$ soliton within $\mathcal{N}=8$ gauged supergravity. By constructing the asymptotic superalgebra, we establish a positive energy t

$\mathcal{N}=1$ S-fold spectroscopy

Autor: Cesàro, Mattia, Larios, Gabriel, Varela, Oscar

We analyse the spectrum of Kaluza-Klein excitations above three distinct families of ${\cal N}=1$ AdS$_4$ solutions of type IIB supergravity of typically non-geometric, S-fold type that have been recently found. For all three families, we provide the
