we find a new obstruction to the existence of solutions of the hull-strominger system, which goes beyond the balanced property of the calabi-yau manifold $(x,\omega)$ and the mumford-takemoto slope stability of the bundle over it. the basic principle is the construction of a (possibly indefinite) hermitian-einstein met... | futaki invariants and yau's conjecture on the hull-strominger system |
we derive the subleading soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary number of finite energy external states carrying arbitrary mass and spin. our results are valid to all orders in perturbation theory when the number of non-compact space-ti... | subleading soft theorem for multiple soft gravitons |
out-of-time-order correlators (otocs) that capture maximally chaotic properties of a black hole are determined by scattering processes near the horizon. this prompts the question to what extent otocs display chaotic behaviour in horizonless microstate geometries. this question is complicated by the fact that lyapunov g... | slow scrambling in extremal btz and microstate geometries |
we show how to combine higgsed topological vertices introduced in [7] with conventional refined topological vertices. we demonstrate that the extended formalism describes very general interacting d5-ns5-d3 brane systems. in particular, we introduce new types of intertwining operators of ding-iohara-miki algebra between... | mixed network calculus |
we consider a broad family of higher-derivative extensions of four-dimensional einstein gravity and study the multipole moments of rotating black holes therein. we carefully show that the various definitions of multipoles carry over from general relativity, and compute these multipoles for higher-derivative kerr using ... | black hole multipoles in higher-derivative gravity |

we review recent progress in the construction of four-dimensional vacua of type ii string theory and f-theory which yield the standard model of particle physics (sm) or extensions thereof. in type ii orientifold compactifications the sm gauge group and chiral spectrum arise from the open string sector of the theory, na... | d-brane and f-theory model building |
the quantum gravity path integral involves a sum over topologies that invites comparisons to worldsheet string theory and to feynman diagrams of quantum field theory. however, the latter are naturally associated with the non-abelian algebra of quantum fields, while the former has been argued to define an abelian algebr... | baby universes and worldline field theories |
using the ambitwistor string, we complete the list of celestial operator product expansion (ope) coefficients for supersymmetric theories. this uses the ambitwistor string worldsheet conformal field theory to dynamically generate the ope coefficients for maximally supersymmetric gauge theory, as well as gravity and ein... | supersymmetric celestial opes and soft algebras from the ambitwistor string worldsheet |
in this paper, we investigate the complexity growth of the tensionless limit of string in the neutral btz black hole horizon in massive gravity. when the string approaches the horizon, we observe a novel phenomenon for the nambu-goto action growth that produces significant difference from tensile string geometry. the s... | complexity growth of btz black hole in massive gravity with a null string |

string stars, or horowitz-polchinski solutions, are euclidean string theory saddles with a normalizable condensate of thermal winding strings. string stars were suggested as a possible description of stringy (euclidean) black holes close to the hagedorn temperature. in this work, we continue the study initiated in [1] ... | the black hole/string transition in ads3 and confining backgrounds |
recently the rydberg blockade effect has been utilized to realize quantum spin liquid (qsl) on a kagome lattice. evidence of qsl has been obtained experimentally by directly measuring non-local string order. in this paper, we report a bardeen-cooper-schrieffer (bcs)-type variational wave function study of the spin liqu... | variational approach to quantum spin liquid in a rydberg atom simulator |
2-group symmetries arise in physics when a 0-form symmetry g[0] and a 1-form symmetry h[1] intertwine, forming a generalised group-like structure. specialising to the case where both g[0] and h[1] are compact, connected, abelian groups (i.e. tori), we analyse anomalies in such `toric 2-group symmetries' using the cobor... | toric 2-group anomalies via cobordism |
we argue that the fundamental "atomic objects" in string theory are themelia: extended objects that have 16 supersymmetries locally. we show that all existing smooth horizonless microstate geometries can be seen as bound states of themelia, and we conjecture that all such bound states with suitable kkm charges will giv... | themelia: the irreducible microstructure of black holes |
we construct villain hamiltonians for compact scalars and abelian gauge theories. the villain integers are promoted to integral spectrum operators, whose canonical conjugates are naturally compact scalars. further, depending on the theory, these conjugate operators can be interpreted as (higher-form) gauge fields. if a... | lattice quantum villain hamiltonians: compact scalars, u(1) gauge theories, fracton models and quantum ising model dualities |

in 1984, 't hooft famously used a brickwall (aka stretched horizon) to compute black hole entropy up to a numerical pre-factor. this calculation is sometimes interpreted as due to the entanglement of the modes across the horizon, but more operationally, it is simply an indirect count of the semi-classical modes trapped... | normal modes of the stretched horizon: a bulk mechanism for black hole microstate level spacing |
string theory in ads3 with purely ns-ns fluxes and vanishing rr moduli has a continuum of winding string excitations in radial plane wave states. btz black holes can emit such strings, which then flow out toward the ads3 boundary as a stream of massive quanta, and form a black hole analogue of the solar wind. the windi... | the holar wind |
n m5-branes probing the intersection between the orbifold ℂ2/γade and an e8 wall give rise to 6d (1, 0) scfts known as ade-type orbi-instantons. at fixed n and order of the orbifold, each element of hom(γade, e8) defines a different scft. the scfts are connected by higgs branch rg flows, which generically reduce the fl... | hierarchy of rg flows in 6d (1, 0) orbi-instantons |

we use the ads/cft correspondence to study the resummation of a perturbative genus expansion appearing in the type ii superstring dual of abjm theory. although the series is borel summable, its borel resummation does not agree with the exact non-perturbative answer due to the presence of complex instantons. the same ty... | resumming the string perturbation series |
with one exception, all known non-supersymmetric ads4 and ads5 vacua of gauged maximal supergravities that descend from string and m theory have been shown to have modes with mass below the bf bound. the remaining non-supersymmetric ads solution is perturbatively stable within gauged maximal supergravity, and hence app... | brane-jet instabilities |
