we investigate the stability of the inner horizon of a rotating btz black hole. we show that linear perturbations arising from smooth initial data are arbitrarily differentiable at the inner horizon if the black hole is sufficiently close to extremality. this is demonstrated for scalar fields, for massive chern-simons ... | the btz black hole violates strong cosmic censorship |
we extend shen's recent formulation (arxiv:1806.07388) of the classical double copy, based on explicit color-kinematic duality, to the case of finite-size sources with non-zero spin. for the case of spinning yang-mills sources, the most general consistent double copy consists of gravitating objects which carry pairs of... | strings, extended objects, and the classical double copy |
we consider type iib 5-brane configurations for 5d rank 2 superconformal theories which are classified recently by geometry in [1]. we propose all the 5-brane web diagrams for these rank 2 theories and show dualities between some of different gauge theories with explicit duality map of mass parameters and coulomb branc... | dualities and 5-brane webs for 5d rank 2 scfts |
previous work has shown that massless tree amplitudes of the type i and iia/b superstrings can be dramatically simplified by expressing them as double copies between field-theory amplitudes and scalar disk/sphere integrals, the latter containing all the α'-corrections. in this work, we pinpoint similar double-copy cons... | heterotic and bosonic string amplitudes via field theory |
string theory has t-duality symmetry when the target space has abelian isometries. a generalization of t-duality, where the isometry group is non-abelian, is known as non-abelian t-duality, which works well as a solution-generating technique in supergravity. in this paper we describe non-abelian t-duality as a kind of ... | type ii dft solutions from poisson-lie t-duality/plurality |

in string theory, an important challenge is to show if the singularity of black holes can be smoothed out by the complete α′ corrections. the simplest case is to consider a 2d string black hole or 3d black string. this problem was discussed in a gauged wess-zumino-witten (wzw) model and the results are supposed to be c... | two-dimensional regular string black hole via complete α′ corrections |

constructing a holographic string theory dual for a cft in the perturbative, weakly coupled regime is a holy grail for gauge/string dualities that would not only open the door for proofs of the ads/cft correspondence but could also provide novel examples of string duals with and without supersymmetry. in this work we c... | engineering perturbative string duals for symmetric product orbifold cfts |

we conjecture that for superconformal field theories in even dimensions, the supersymmetric casimir energy on a space with topology s 1 × sd-1 is equal to an equivariant integral of the anomaly polynomial. the equivariant integration is defined with respect to the cartan subalgebra of the global symmetry algebra that c... | supersymmetric casimir energy and the anomaly polynomial |
aspects of the low energy physics of certain jackiw-teitelboim gravity and supergravity theories are explored, using their recently presented non-perturbative description in terms of minimal string models. this regime necessarily involves non-perturbative phenomena, and the inclusion of wormhole geometries connecting m... | low energy thermodynamics of jt gravity and supergravity |
we study local operator insertions on 1/2-bps line defects in abjm theory. specifically, we consider a class of four-point correlators in the cft1 with su(1, 1|3) super- conformal symmetry defined on the 1/2-bps wilson line. the relevant insertions belong to the short supermultiplet containing the displacement operator... | analytic bootstrap and witten diagrams for the abjm wilson line as defect cft1 |
it has been suggested that low energy effective field theories should satisfy given conditions in order to be successfully embedded into string theory. in the case of a single canonically normalized scalar field this translates into conditions on its potential and the derivatives thereof. in this letter we revisit smal... | eternal inflation, entropy bounds and the swampland |
