In this paper we discuss the supersymmetric localization of the 4D $ \mathcal{N} $ = 2 offshell gauged supergravity on the background of the AdS$_{4}$ neutral topological black hole, which is the gravity dual of the ABJM theory defined on the boundary $ {\mathrm{S}}^1\times {\mathrm{\mathbb{H}}}^2 $ . We compute the large-N expansion of the supergr...

The low-energy description of wrapped M5 branes in compactifications of M-theory on a Calabi-Yau threefold times a circle is given by a conformal field theory studied by Maldacena, Strominger and Witten and known as the MSW CFT. Taking the threefold to be $ {\mathbb{T}}_6 $ or $ \mathrm{K}3\times {\mathbb{T}}^2 $ , we construct a map between a sub-...

We study BPS bound states of little strings in a limit where they realize monopole strings in five dimensional gauge theories. The latter have gauge group U(M)N and arise from compactification of (1,0) little string theories of type AM-1×AN-1. We find evidence that the partition function of a certain subclass of monopole strings of charge (k,…,k) (...

In one dimension, the area law and its implications for the approximability by matrix product states are the key to efficient numerical simulations involving quantum states. Similarly, in simulations involving quantum operators, the approximability by matrix product operators (in Hilbert–Schmidt norm) is tied to an operator area law, namely the fac...

We study supersymmetric intersections of NS5-, D6- and D8-branes in type IIA string theory. We focus on the supergravity description of this system and identify a “near horizon” limit in which we recover the recently classified supersymmetric seven-dimensional AdS solutions of massive type IIA supergravity. Using a consistent truncation to seven-di...

Holographic models provide unique laboratories to investigate nonlinear physics of transport in inhomogeneous systems. We provide a detailed account of both dc and ac conductivities in a defect conformal field theory with spontaneous stripe order. The spatial symmetry is broken at large chemical potential, and the resulting ground state is a combin...

We study quantum aspects of the recently constructed doubly λ -deformed σ -models representing the effective action of two WZW models interacting via current bilinears. We show that although the exact beta-functions and current anomalous dimensions are identical to those of the λ -deformed models, this is not true for the anomalous dimensions of ge...

Motivated by the absence of signals of new physics at the LHC, which seems to imply the presence of large mass hierarchies, we investigate the theoretical possibility that these could arise dynamically in new strongly-coupled gauge theories extending the standard model of particle physics. To this purpose, we study lattice data on non-Abelian gauge...

In the presence of boundaries the integrated conformal anomaly is modified by the boundary terms so that the anomaly is non-vanishing in any (even or odd) dimension. The boundary terms are due to extrinsic curvature whose exact structure in d=3 and d=4 has recently been identified. In this note we present a holographic calculation of those terms in...

We consider a general class of asymptotically locally AdS5 solutions of minimal gauged supergravity, which are dual to superconformal field theories on curved backgrounds S1×M3 preserving two supercharges. We demonstrate that standard holographic renormalization corresponds to a scheme that breaks supersymmetry. We propose new boundary terms that r...
