Additivity, Haag duality, and non-invertible symmetries
Shu-Heng Shao, Jonathan Sorce, Manu Srivastava
The algebraic approach to quantum field theory focuses on the properties of local algebras, whereas the study of (possibly non-invertible) global symmetries emphasizes global aspec…
On the Causality Paradox and the Karch-Randall Braneworld as an EFT
Dominik Neuenfeld, Manu Srivastava
Holography on cutoff surfaces can appear to be in tension with causality. For example, as argued by Omiya and Wei [arxiv:2107.01219], double holography seemingly allows for superlu…
Generalized Lense--Thirring metrics: higher-curvature corrections and solutions with matter
Finnian Gray, Robie A. Hennigar, David Kubiznak +2
The Lense--Thirring spacetime describes a 4-dimensional slowly rotating approximate solution of vacuum Einstein equations valid to a linear order in rotation parameter. It is fully…
Complexity of Scalar Collapse in Anti-de Sitter Spacetime
Andrew R. Frey, Michael P. Grehan, Manu Srivastava
We calculate the volume and action forms of holographic complexity for the gravitational collapse of scalar field matter in asymptotically anti-de Sitter spacetime, using numerical…
Gravitational radiation close to a black hole horizon: Waveform regularization and the out-going echo
Manu Srivastava, Yanbei Chen
Black hole perturbation theory for Kerr black holes is best studied in the Newman Penrose Formalism, in which gravitational waves are described as perturbations in the Weyl scalars…
Analytical computation of quasi-normal modes of slowly-rotating black-holes in dCS gravity
Manu Srivastava, Yanbei Chen, S. Shankaranarayanan
Using gravitational wave observations to search for deviations from general relativity in the strong-gravity regime has become an important research direction. Chern Simons (CS) gr…
Gravitational-wave echoes from spinning exotic compact objects: numerical waveforms from the Teukolsky equation
Shuo Xin, Baoyi Chen, Rico K. L. Lo +7
We present numerical waveforms of gravitational-wave echoes from spinning exotic compact objects (ECOs) that result from binary black hole coalescence. We obtain these echoes by so…
Non-trivial quantum fluctuations in asymptotically non-flat black-hole space-times
Manu Srivastava, S. Shankaranarayanan
Hawking radiation remains a crucial theoretical prediction of semi-classical gravity and is considered one of the critical tests for a model of quantum gravity. However, Hawking's…
