we construct a background for m-theory that is moduli free. this background is then shown to be related to a topological phase of the e8(8) exceptional field theory (exft). the key ingredient in the construction is the embedding of non-riemannian geometry in exft. this allows one to describe non-relativistic geometries... | non-riemannian geometry of m-theory |
we consider a generalization of elliptic multiple zeta values, which we call twisted elliptic multiple zeta values. these arise as iterated integrals on an elliptic curve from which a rational lattice has been removed. at the cusp, twisted elliptic multiple zeta values are shown to degenerate to cyclotomic multiple zet... | twisted elliptic multiple zeta values and non-planar one-loop open-string amplitudes |

we revisit necessary conditions for gluing local (anti-)d3 throats into flux throats with opposite charge. these consistency conditions typically reveal singularities in the 3-form fluxes whose meaning is being debated. in this note we prove, under well-motivated assumptions, that unphysical singularities can potential... | observations on fluxes near anti-branes |
superstring field theory gives expressions for heterotic and type ii string loop amplitudes that are free from ultraviolet and infrared divergences when the number of non-compact space-time dimensions is five or more. we prove the subleading soft graviton theorem in these theories to all orders in perturbation theory f... | subleading soft graviton theorem for loop amplitudes |

we study the behaviour of abelian gauge symmetries in six-dimensional n = (1 ,0) theories upon decoupling gravity and investigate abelian flavour symmetries in the context of 6d n = (1 , 0) scfts. from a supergravity perspective, the anomaly cancellation mechanism implies that abelian gauge symmetries can only survive ... | 6d scfts and u(1) flavour symmetries |
we reformulate the monodromy relations of open-string scattering amplitudes as boundary terms of twisted homologies on the configuration spaces of riemann surfaces of arbitrary genus. this allows us to write explicit linear relations involving loop integrands of open-string theories for any number of external particles... | monodromy relations from twisted homology |
in the string theory, the fundamental blocks of nature are not particles but one-dimensional strings. therefore, a generalization of this idea is to think of it as a cloud of strings. rodrigues et al. embedded the black bounces spacetime into the string cloud, which demonstrates that the existence of the string cloud m... | ringing and echoes from black bounces surrounded by the string cloud |
we study generating functions of moduli-space integrals at genus one that are expected to form a basis for massless n-point one-loop amplitudes of open superstrings and open bosonic strings. these integrals are shown to satisfy the same type of linear and homogeneous first-order differential equation w.r.t. the modular... | one-loop open-string integrals from differential equations: all-order α'-expansions at n points |

in this note we investigate the role of lloyd's computational bound in holographic complexity. our goal is to translate the assumptions behind lloyd's proof into the bulk language. in particular, we discuss the distinction between orthogonalizing and `simple' gates and argue that these notions are useful for diagnosing... | complexity is simple! |
we survey physical models which capture the main concepts of double field theory on para-hermitian manifolds. we show that the geometric theory of lagrangian and hamiltonian dynamical systems is an instance of para-kahler geometry which extends to a natural example of a born geometry. the corresponding phase space geom... | para-hermitian geometry, dualities and generalized flux backgrounds |
we use deep autoencoder neural networks to draw a chart of the heterotic z6-ii orbifold landscape. even though the autoencoder is trained without knowing the phenomenological properties of the z6-ii orbifold models, it identifies fertile islands in this chart where phenomenologically promising models cluster. then, we ... | deep learning in the heterotic orbifold landscape |
the formalism of matrix product states is used to perform a numerical study of (1 +1 )-dimensional qed—also known as the (massive) schwinger model—in the presence of an external static "quark" and "antiquark". we obtain a detailed picture of the transition from the confining state at short interquark distances to the b... | confinement and string breaking for qed2 in the hamiltonian picture |

we propose a novel modular anomaly equation for the unflavored schur index in the n = 4 su(n) super-yang-mills theory. the vanishing conditions overdetermine the modular ambiguity ansatz from the equation, thus together they are sufficient to recursively compute the exact schur indices for all su(n) gauge groups. using... | modular anomaly equation for schur index of n = 4 super-yang-mills |
we discuss the formation of cosmic strings or macroscopic color flux tubes after the deconfinement/confinement phase transition in the pure yang-mills theory. based on holographic dual descriptions, these cosmic strings can be interpreted as fundamental (f-) strings or wrapped d-branes (which we call as d-strings) in t... | cosmic f- and d-strings from pure yang-mills theory |

a surprising result in e+e- collisions is that the particle spectra from the string formed between the expanding quark-antiquark pair have thermal properties even though scatterings appear not to be frequent enough to explain this. we address this problem by considering the finite observable interval of a relativistic ... | thermal excitation spectrum from entanglement in an expanding quantum string |

axionlike particles (alps) with couplings to electromagnetism have long been postulated as extensions to the standard model. string theory predicts an "axiverse" of many light axions, some of which may make up the dark matter in the universe and/or solve the strong c p problem. we propose a new experiment using superco... | probing axionlike particles and the axiverse with superconducting radio-frequency cavities |
we show that the cosmological abundance of string axions is much smaller than naive estimates if the hubble scale of inflation, h inf , is sufficiently low (but can still be much higher than the axion masses) and if the inflation lasts sufficiently long. the reason is that the initial misalignment angles of the string ... | relaxing the cosmological moduli problem by low-scale inflation |
the holomorphic anomaly equations describe b-model closed topological strings in calabi-yau geometries. having been used to construct perturbative expansions, it was recently shown that they can also be extended past perturbation theory by making use of resurgent transseries. these yield formal nonperturbative solution... | resurgent transseries and the holomorphic anomaly: nonperturbative closed strings in local |

we prove the conditions under which scaling cosmologies are inevitable late-time attractors of multifield multiexponential potentials, independently of initial conditions. the advantage of such scaling cosmologies is that the time dependence of the fields and of the scale factor is known analytically, thus allowing lat... | late-time attractors and cosmic acceleration |
the p-body syk model at finite temperature exhibits submaximal chaos and contains stringy-like corrections to the dual jt gravity. it can be solved exactly in two different limits: "large p" syk 1 ≪ p ≪ n and "double-scaled" syk n, p → ∞ with λ = 2p2/n fixed. we clarify the relation between the two. starting from the e... | large p syk from chord diagrams |
heavy-ion collisions at center-of-mass nucleon collision energies 4.5-11.5 gev are analyzed within the parton-hadron-string dynamics (phsd) transport model. spectator nucleons are separated, and the transfer of the initial angular momentum of colliding nuclei to the fireball formed by participants is studied. the maxim... | helicity and vorticity in heavy-ion collisions at energies available at the jinr nuclotron-based ion collider facility |
