The Penrose Transform and the Kerr-Schild double copy
Emma Albertini, Michael L. Graesser, Gabriel Herczeg
There are a number of classical double copies, each providing a prescription for generating solutions to the Maxwell and scalar wave equations from exact solutions of Einstein's eq…
Taub-NUT Instanton as the Self-dual Analog of Kerr
Jash Desai, Gabriel Herczeg, David McNutt +1
It was recently conjectured that a certain vacuum Kerr-Schild spacetime, which may be regarded as a self-dual analog of the Kerr metric, is equivalent to the self-dual Taub-NUT ins…
Double Kerr-Schild spacetimes and the Newman-Penrose map
Kara Farnsworth, Michael Graesser, Gabriel Herczeg
The Newman-Penrose map, which is closely related to the classical double copy, associates certain exact solutions of Einstein's equations with self-dual solutions of the vacuum Max…
An Inner Product for 4D Quantum Gravity and the Chern-Simons-Kodama State
Stephon Alexander, Laurent Freidel, Gabriel Herczeg
We demonstrate that reality conditions for the Ashtekar connection imply a non-trivial measure for the inner product of gravitational states in the polarization where the Ashtekar…
Twistor Space Origins of the Newman-Penrose Map
Kara Farnsworth, Michael L. Graesser, Gabriel Herczeg
Recently, we introduced the "Newman-Penrose map," a novel correspondence between a certain class of solutions of Einstein's equations and self-dual solutions of the vacuum Maxwell…
The Newman-Penrose Map and the Classical Double Copy
Gilly Elor, Kara Farnsworth, Michael L. Graesser +1
Gauge-gravity duality is arguably our best hope for understanding quantum gravity. Considerable progress has been made in relating scattering amplitudes in certain gravity theories…
Contact Quantization: Quantum Mechanics = Parallel transport
G. Herczeg, E. Latini, A. Waldron
Quantization together with quantum dynamics can be simultaneously formulated as the problem of finding an appropriate flat connection on a Hilbert bundle over a contact manifold. C…
Contact Geometry and Quantum Mechanics
Gabriel Herczeg, Andrew Waldron
We present a generally covariant approach to quantum mechanics in which generalized positions, momenta and time variables are treated as coordinates on a fundamental "phase-spaceti…
