Monodromy Defects in Massive Type IIA

Andrea Conti, Yolanda Lozano, Christopher Rosen

In this paper we study solutions to massive Type IIA supergravity which we propose are dual to co-dimension 2 monodromy defects in 6d (1,0) CFTs realised in NS5-D6-D8 brane systems…

Defect entanglement entropy for superconformal monodromy defects

Andrea Conti, Yolanda Lozano, Filippos Rogdakis +1

We compute the defect entanglement entropy for co-dimension two superconformal monodromy defects in well known maximally symmetric holographic theories of various dimension. In eac…

( $0, 6$ ) AdS $_{3}$ /CFT $_{2}$ and surface defects

Yolanda Lozano, Anayeli Ramirez

We explore a new class of AdS $_{3}$ solutions in massive type IIA supergravity preserving $N = (0, 6)$ supersymmetry and realising an $osp (6∣2)$ superconformal al…

$N = 6$ supersymmetric AdS $_{2} \times CP^{3} \times Σ_{2}$

Andrea Conti, Yolanda Lozano, Niall T. Macpherson

We perform a complete classification of AdS $_{2}$ solutions of Type II supergravity realising $N = 6$ supersymmetry and OSp $(6∣2)$ superconformal symmetry on backgrounds that…

On $AdS_{2} \times S^{7}$ , its $Z_{k}$ orbifold and their dual quantum mechanics

Yolanda Lozano, Niall T. Macpherson, Achilleas Passias

We consider a previously constructed class of massive Type IIA AdS $_{2} \times$ S $^{7} \times I$ solutions with OSp $(8∣2)$ symmetry, as well as OSp $(6∣2)$ -symmetric ones, by replacing the…

Deconstruction and surface defects in 6d CFTs

Andrea Conti, Giuseppe Dibitetto, Yolanda Lozano +2

We study the two families of AdS $_{3} \times S^{3} \times S^{2} \times Σ_{2}$ solutions to massive Type IIA supergravity with small and large $(0, 4)$ supersymmetries constructed recently in t…

Half-BPS Janus solutions in AdS $_{7}$

Andrea Conti, Giuseppe Dibitetto, Yolanda Lozano +2

We study half-BPS flows in gauged minimal 7d supergravity featured by an AdS $_{3} \times S^{3}$ slicing of the metric, supported by a dyonic three-form field. We first present a novel s…
