    Princeton University Gravity Initiative Lunch
    “Neutron star mergers: On the impact of high spins in multi-messenger gravitational wave events”

    Location: via ZOOM
    Time: 12:30 PM
    Speaker(s): Elias Most, Princeton University; Member, School of Natural Sciences

    Description:

    Since the first detection of a gravitational wave event of the merger of two neutron stars in 2017, two more detections in the neutron star mass range have been announced earlier this year. The first one, GW190425, involved an unusually massive neutron star, the second one, GW190814, had a companion in the lower mass gap that could either have been the heaviest neutron star or the lightest black hole ever observed. One of the uncertainties in those detections is allowing for the possibility of having high initial spins before the merger.  

    In this talk, I will discuss the potential observational impact of the presence of high spins in the inspiral. In particular, I will show what effect high spins can have on the emission of – yet to be observed – electromagnetic precursors and on the mass ejected dynamically during the merger process.

    This will be followed by the presentation of a new method to place limits on high spins and small mass ratios in mergers involving a very massive neutron star, such as GW190425.

    Finally, I will comment on potential implications for the equation of state, in case the secondary in GW190814 was (once) a neutron star. Following up on the possibility of having low mass black holes in the lower mass gap, I will present the results of an on-going study of near equal mass black hole-neutron star mergers. In particular, I will focus on the impact of initial black hole spin on the viability for electromagnetic counterparts.

    Meeting ID: 924 6779 0530

    Abstract: I will demonstrate that holographic error correcting codes naturally give rise to conditional expectations acting on the local operator algebras in the boundary theory. I will use this to give simple derivations of some previously known results as well as some new results when multiple boundary/bulk algebras are considered. Connections to the theory of QFT superselection sectors will be discussed. I will also discuss some shortcomings of these codes as models of AdS/CFT.

    “Leading order corrections to the quantum extremal surface prescription”

    Meeting ID: 924 6779 0530

    Abstract: We show that a naïve application of the quantum extremal surface (QES) prescription can lead to paradoxical results and must be corrected at leading order. The corrections arise when there is a second QES (with strictly larger generalized entropy at leading order than the minimal QES), together with a large amount of highly incompressible bulk entropy between the two surfaces. We trace the source of the corrections to a failure of the assumptions used in the replica trick derivation of the QES prescription, and show that a more careful derivation correctly computes the corrections. Using tools from one-shot quantum Shannon theory (smooth min-and max-entropies), we generalize these results to a set of refined conditions that determine whether the QES prescription holds. We find similar refinements to the conditions needed for entanglement wedge reconstruction (EWR), and show how EWR can be reinterpreted as the task of one-shot quantum state merging (using zero-bits rather than classical bits), a task gravity is able to achieve optimally efficiently.
