using the double-copy construction of yang-mills-einstein theories formulated in our earlier work, we obtain compact presentations for single-trace yang-mills-einstein tree amplitudes with up to five external gravitons and an arbitrary number of gluons. these are written as linear combinations of color-ordered yang-mil... | explicit formulae for yang-mills-einstein amplitudes from the double copy |
in this paper we propose a quantum version of the swampland conjecture. we argue that quantum instabilities of de sitter space discovered using field theoretical methods, are directly related to the difficulties in finding stringy de sitter vacua. | the quantum swampland |
we systematically analyse weak coupling limits for 2-form tensor fields in the presence of gravity. such limits are significant for testing various versions of the weak gravity and swampland distance conjectures, and more broadly, the phenomenon of emergence. the weak coupling limits for 2-forms correspond to certain i... | emergent strings, duality and weak coupling limits for two-form fields |
we establish a map between ads3×s2 and ads7 solutions to massive iia supergravity that allows one to interpret the former as holographic duals to d2-d4 defects inside 6d (1,0) cfts. this relation singles out in a particular manner the ads3×s2 solution constructed from ads3×s3×cy2 through non-abelian t-duality, with res... | ads3 solutions in massive iia, defect cfts and t-duality |

correlators in symmetric orbifold cfts are given by a finite sum of admissible branched covers of the 2d spacetime. we consider a gross-mende like limit where all operators have large twist, and show that the corresponding branched covers can be described via a penner-like matrix model. the limiting branched covers are... | from symmetric product cfts to ads3 |
we consider α' corrections to the one-loop four-point correlator of the stress- tensor multiplets in n = 4 super yang-mills at order 1/n4. holographically, this is dual to string corrections of the one-loop supergravity amplitude on ads5 × s5. while this correlator has been considered in mellin space before, we derive ... | one-loop string corrections to ads amplitudes from cft |
it was recently shown that the theory obtained by deforming a general two dimensional conformal theory by the irrelevant operator t\overline{t} is solvable. in the context of holography, a large class of such theories can be obtained by studying string theory on ads 3. we show that a certain single trace t\overline{t} ... | t\\overline{t} and lst |

string consistency conditions are stronger than anomaly cancellation and can require the addition of exotics in the visible sector. we study such exotics and demonstrate that they may account for the modest excess at $750$ gev in recent diphoton resonance searches performed by the atlas and cms collaborations. in a pre... | string consistency, heavy exotics, and the 750 gev diphoton excess at the lhc |
higher-derivative corrections to cosmological effective actions in string theory are largely constrained by t-duality, but have been computed hitherto only to the first few orders in the string scale α'. the functional renormalization group, in conjunction with the strong constraints imposed by t-duality, allows us to ... | string tension between de sitter vacua and curvature corrections |
we study limits of infinite distance in the moduli space of 4d n = 2 string compactifications, in which instanton effects dominate. we first consider trajectories in the hypermultiplet moduli space of type iib calabi-yau compactifications. we observe a correspondence between towers of d-brane instantons and d-brane 4d ... | instanton corrections and emergent strings |
anomaly matching constrains low-energy physics of strongly-coupled field theories, but it is not useful at finite temperature due to contamination from high-energy states. the known exception is an 't hooft anomaly involving one-form symmetries as in pure su( n ) yang-mills theory at θ = π. recent development about lar... | circle compactification and 't hooft anomaly |
given the recent geometrical classification of 6d (1, 0) scfts, a major question is how to compute for this large class their elliptic genera. the latter encode the refined bps spectrum of the scfts, which determines geometric invariants of the associated elliptic non-compact calabi-yau threefolds. in this paper we est... | elliptic blowup equations for 6d scfts. part iv. matters |

the role of the brane in providing de sitter vacua with spontaneously broken supersymmetry in the kklt construction is clarified. the first step in this direction was explained in [1, 2]: it was shown there that in the gkp background the bosonic contributions to the vacuum energy from the dbi and wz term cancel for a d... | and ds |
