Fine-Grained Chaos in Gravity
Felix M. Haehl, Moshe Rozali
Quantum chaos can be characterized by an exponential growth of the thermal out-of-time-order four-point function up to a scrambling time . We discuss generalizations…
Higher Curvature Gravity from Entanglement in Conformal Field Theories
Felix M. Haehl, Eliot Hijano, Onkar Parrikar +1
By generalizing different recent works to the context of higher curvature gravity, we provide a unifying framework for three related results: (i) If an asymptotically AdS spacetime…
Schwinger-Keldysh superspace in quantum mechanics
Michael Geracie, Felix M. Haehl, R. Loganayagam +3
We examine, in a quantum mechanical setting, the Hilbert space representation of the BRST symmetry associated with Schwinger-Keldysh path integrals. This structure had been postula…
Thermal out-of-time-order correlators, KMS relations, and spectral functions
Felix M. Haehl, R. Loganayagam, Prithvi Narayan +2
We describe general features of thermal correlation functions in quantum systems, with specific focus on the fluctuation-dissipation type relations implied by the KMS condition. Th…
Nonlinear Gravity from Entanglement in Conformal Field Theories
Thomas Faulkner, Felix M. Haehl, Eliot Hijano +3
In this paper, we demonstrate the emergence of nonlinear gravitational equations directly from the physics of a broad class of conformal field theories. We consider CFT excited sta…
Two roads to hydrodynamic effective actions: a comparison
Felix M. Haehl, R. Loganayagam, Mukund Rangamani
We make a detailed comparison between two attempts in recent years to construct hydrodynamic effective actions: we compare our work [1-7] with that of Crossley-Glorioso-Liu [8] and…
Towards a second law for Lovelock theories
Sayantani Bhattacharyya, Felix M. Haehl, Nilay Kundu +2
In classical general relativity described by Einstein-Hilbert gravity, black holes behave as thermodynamic objects. In particular, the laws of black hole mechanics can be interpret…
Classification of out-of-time-order correlators
Felix M. Haehl, R. Loganayagam, Prithvi Narayan +1
The space of n-point correlation functions, for all possible time-orderings of operators, can be computed by a non-trivial path integral contour, which depends on how many time-ord…
