  • Closed-form expression for cross-channel conformal blocks near the lightcone

    Wenliang Li

    … Based on the nonperturbative pole structure in spin of Lorentzian inversion, we propose the natural basis functions for cross-channel conformal blocks. … In this new basis, we find a closed-form expression for crossed conformal blocks in terms of the Kampe de Feriet function, which applies to intermediate operators of arbitrary spin in general dimensions. … Our results for the lightcone limit also shed light on the complete analytic structure of conformal blocks in the lightcone expansion. …

  • Analysis of flow and acoustic radiation in reed instruments by compressible flow simulation

    Yokoyama Hiroshi , Kobayashi Masanori , Iida Akiyoshi

    … <p>Direct aeroacoustic simulations of flow and sound around an instrument with an oscillating reed were performed on the basis of compressible Navier–Stokes equations along with experiments with an artificial blowing device. … It was found that compression and expansion occur inside the mouthpiece, where the flow separation occurs after the spreading of the air jet from the reed channel exit along the inner wall of the mouthpiece. …

  • Multipole-based distance-dependent screening of Coulomb integrals

    Andreas Irmler , Fabian Pauly

    … We derive a new estimate for two-electron repulsion integrals (ERIs), when evaluated within a local atomic basis set. … It is based on the multipole expansion and provides a rigorous upper bound of an ERI for well-separated charge distributions. … Using Gaussian basis functions, we show that the estimate allows us to accelerate the construction of the exchange matrix by up to a factor of two without introducing further approximations. …
