    por Giddings, Steven B.
    Publicado 2019
    “…An interesting question is to characterize the general class of allowed boundary conditions for gauge theories, including gravity, at spatial and null infinity. This has played a role in discussions of soft charges, where antipodal symmetry has typically been assumed. …”

    Generalized asymptotics for gauge fields
  2. 3302
    “…We discuss the implication of these results for products of CFT partition functions in gravity and Euclidean wormholes. Our results suggest that there are new connected wormhole geometries that dominate over the genus-two wormhole.…”

    Gravitational portals with nonminimal couplings
  4. 3304
    “…As a byproduct we give in general the full duality group (quantum monodromy) for an arbitrary rigid SU(r+1) gauge theory, extending previous explicit constructions for the r=1,2 cases. In the coupling to gravity, R--symmetry and monodromy groups of the dynamical Riemann surface, whose structure we discuss in detail, is embedded into the symplectic duality group \Gamma_D associated with the moduli space of the dynamical Calabi--Yau threefold.…”

    A search for non-perturbative dualities of local N=2 Yang-Mills theories from Calabi-Yau threefolds
  5. 3305
    “…They appear as holographic dual to theories of (strongly coupled) gravity. For instance, in Holographic Cosmology, the two-point function of the Energy-Momentum Tensor (EMT) of a particular class of three-dimensional QFTs can be mapped into the power spectrum of the Cosmic Microwave Background in the gravitational theory. …”

    Position-Space Renormalisation of the Energy-Momentum Tensor

    por Sfetsos, Konstadinos
    Publicado 1998
    “…We also discuss supersymmetric properties of the various solutions and the relation to 2-dim solitons, on flat space, of the reduced axion-dilaton-gravity equations. Finally, we address the problem of understanding other supergravity solutions from the multicenter ones. …”

    Branes for Higgs phases and exact conformal field theories
  7. 3307
    por Pilaftsis, Apostolos
    Publicado 1999
    “…We study the scenario of baryogenesis through leptogenesis in higher-dimensional theories, in which the scale of quantum gravity may be as low as few TeV. The minimal realization of these theories includes an isosinglet neutrino which is considered to propagate in large compact dimensions, whereas all the SM particles are localized on a (1+3)-dimensional wall. …”

    “…We derive an expression for the angular power spectrum of cosmic microwave background anisotropies due to gravity waves generated by a stochastic magnetic field and compare the result with current observations; we take into account the non-linear nature of the stress energy tensor of the magnetic field. …”

    Current correlators in the Coulomb branch of N=4 SYM

    “…We investigate the properties of scalar fields arising from gravity propagating in extra dimensions. In the scenario of large extra dimensions, proposed by Arkani-Hamed, Dimopoulos and Dvali (1998), graviscalar Kaluza-Klein excitations are less important than the spin-2 counterparts in most processes. …”

    “…The SBM-Tobit model and GIS were employed to analyze AEE based on the carbon emission evaluation system in the spatial and temporal characteristics, as well as the influencing factors and the migration path of the center of gravity in the “low carbon” context. A rational plan of agricultural production was proposed according to the results. …”

    “…The most important aspect of this study was establishing the optimum particle size for sustained floatation and balancing the buoyancy and gravity effect. The results show that the particles sink with a larger than optimum particle size because of the gravity effect. …”

    “…Neutral buoyancy removes somatosensory cues to the direction of gravity but leaves vestibular cues intact. Removal of both somatosensory and direction of gravity cues while floating in microgravity or using virtual reality to establish conflicts between them has been shown to affect the perception of distance traveled in response to visual motion (vection) and the perception of distance. …”

    “…High dimensional electromyogram (EMG) vectors were generated as several arm and trunk muscles were recorded while subjects pointed at various angles above and below the gravity neutral horizontal plane. We used Linear Discriminant Analysis (LDA) to carry out binary classifications between the EMG vectors for pointing at a particular angle, vs. pointing at the gravity neutral direction. …”
