Abstract

Building on the recent discovery of the first candidate black hole operator in N = 4 super-Yang-Mills, we explore the near-supersymmetric aspects of the theory that capture lightly excited, highly stringy black holes. We extend the superspace formalism describing the classically supersymmetric (1/16-BPS) sector of N = 4 super-Yang-Mills and compute a large number of one-loop anomalous dimensions. Despite being in the highly stringy regime, we find hints of a gap in the spectrum, similar to that found by a gravitational path integral. We also determine the actual expression of the first candidate black hole operator at weak gauge coupling, going beyond the cohomological construction.

  • Quantum Aspects of Black Holes

    PrerequisiteGeneral Relativity, Field Theory, String TheoryAbstractStarting with an overview of the classical/semi-classical aspects of black holes, this course will emphasise black hole quantum aspects. We will review the basic aspects of these objects and their thermodynamics, the derivation of Hawking radiation and examine different formulations/resolutions of the information paradox. Then w...
