pp-Waves and the Hidden Symmetries of Black Hole Quasinormal Modes
Daniel Kapec, Ahmed Sheta
There are two interesting classes of trapped null geodesics in any black hole spacetime: those that lie on the photon ring and those that generate the horizon. Recent work introduc…
Quasinormal Corrections to Near-Extremal Black Hole Thermodynamics
Daniel Kapec, Y. T. Albert Law, Chiara Toldo
Recent work on the quantum mechanics of near-extremal non-supersymmetric black holes has identified a characteristic scaling of the low temperature black hole partition f…
Logarithmic Corrections to Kerr Thermodynamics
Daniel Kapec, Ahmed Sheta, Andrew Strominger +1
Recent work has shown that loop corrections from massless particles generate corrections to black hole entropy which dominate the thermodynamic…
Comments on the Quantum Field Theory of the Coulomb Gas Formalism
Daniel Kapec, Raghu Mahajan
The holomorphic Coulomb gas formalism is a set of rules for computing minimal model observables using free field techniques. We attempt to derive and clarify these rules using stan…
Matrix ensembles with global symmetries and 't Hooft anomalies from 2d gauge theory
Daniel Kapec, Raghu Mahajan, Douglas Stanford
The Hilbert space of a quantum system with internal global symmetry decomposes into sectors labelled by irreducible representations of . If the system is chaotic, the energi…
Particle motion near high-spin black holes
Daniel Kapec, Alexandru Lupsasca
General relativity predicts that the Kerr black hole develops qualitatively new and surprising features in the limit of maximal spin. Most strikingly, the region of spacetime near…
