    Publicado 2019
    “…It has previously been proposed that the black hole interior of typical state large black holes in AdS can be described using state-dependent operators. …”

    “…An observable stochastic background of gravitational waves is generated whenever primordial black holes are created in the early universe thanks to a small-scale enhancement of the curvature perturbation. …”

    “…While scaling relations are used to rescale simulations for very massive black holes, primordial black holes have specific properties which can invalidate the rescaling. …”

    “…The enhancement of the spectrum of primordial comoving curvature perturbation R can induce the production of primordial black holes (PBH) which could account for part of present day dark matter. …”

    “…By combining analytic and numerical approaches, we show that in systems with a holographic dual, the saturation time is equal to this lower bound for a variety of differently shaped entangling surfaces, implying that the dual black holes saturate the entanglement entropy as fast as possible. …”

    por Romano, Antonio Enea
    Publicado 2020
    “…We study different mechanisms by which the speed of primordial curvature perturbations can produce an enhancement of the curvature spectrum, which could lead to the production of primordial black holes (PBH). One possibility is the growth of the sound speed in single scalar field models, which can induce super-horizon growth of curvature perturbations. …”

    “…We conjecture that the Higgs potential can be significantly modified when it is in close proximity to the horizon of an astrophysical black hole, leading to the destabilization of the electroweak vacuum. …”

    “…In modern theoretical ideas related to the concept of extra dimensions and multidimensional low-energy gravity, one can expect to observe the creation of the microscopic black holes at the LHC in proton-proton collisions at currently available energies.…”

    “…It has been recently pointed out that nonlinear effects are necessary to model the ringdown stage of the gravitational waveform produced by the merger of two black holes giving rise to a remnant Kerr black hole. We show that this nonlinear behavior is explained, both on the qualitative and quantitative level, by near-horizon symmetries of the Kerr black hole within the Kerr/CFT correspondence.…”

    por Khuri, Ramzi R., Myers, Robert C.
    Publicado 1995
    “…In a recent paper, Duff and Rahmfeld argued that certain massive N_R=1/2 states of the four-dimensional heterotic string correspond to extreme black hole solutions. We provide further, dynamical, evidence for this identification by comparing the scattering of these elementary string states with that of the corresponding extreme black holes, in the limit of low velocities.…”

    por Daniels, R D, Shore, Graham M
    Publicado 1995
    “…In this paper, we extend our analysis of photon propagation in gravitational backgrounds to the Kerr spacetime describing a rotating black hole. The results support two general theorems -- a polarisation sum rule and a `horizon theorem'. …”
