Potential Carroll Structures and Special Carrollian Manifolds
Samuel Blitz, Gabriel Herczeg, David McNutt
It is well-known that unlike space-like and time-like hypersurfaces, null hypersurfaces in Lorentzian manifolds do not naturally inherit an affine connection from the spacetime in…
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…
Isometries and the double copy
Damien A. Easson, Gabriel Herczeg, Tucker Manton +1
In the standard derivation of the Kerr-Schild double copy, the geodicity of the Kerr-Schild vector and the stationarity of the spacetime are presented as assumptions that are neces…
Dynamical Henneaux-Teitelboim Gravity
Emma Albertini, Kyle Barnes, Gabriel Herczeg
We consider a modified gravity model which we call "dynamical Henneaux-Teitelboim gravity" because of its close relationship with the Henneaux-Teitelboim formulation of unimodular…
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…
Torsion and the Probability of Inflation
Emma Albertini, Stephon Alexander, Gabriel Herczeg +1
We revisit the problem of the "probability of inflation" from the point of view of the Einstein-Cartan theory, where torsion can be present off-shell even in the absence of spinori…
Black hole and cosmological analysis of BF sequestered gravity
Stephon Alexander, Steven J. Clark, Gabriel Herczeg +1
We study a minimal extension of a recently proposed modification of general relativity that draws on concepts from topological field theory to resolve aspects of the cosmological c…
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…
Dynamical Quantization of Contact Structures
Roger Casals, Gabriel Herczeg, Andrew Waldron
We construct a dynamical quantization for contact manifolds in terms of a flat connection acting on a Hilbert tractor bundle. We show that this contact quantization, which is indep…
A generalized Hartle-Hawking wavefunction
Stephon Alexander, Gabriel Herczeg, Joao Magueijo
The Hartle-Hawking wave function is known to be the Fourier dual of the Chern-Simons or Kodama state reduced to mini-superspace, using an integration contour covering the whole rea…
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…
Chiral Symmetry and the Cosmological Constant
Stephon Alexander, Gabriel Herczeg, Jinglong Liu +1
In this work we provide a link between a nearly vanishing cosmological constant and chiral symmetry. This is accomplished with a modification of General Relativity coupled to a top…
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…
A Tour Through Shape Dynamic Black Holes
Gabriel Herczeg
Shape dynamics is a classical theory of gravity which agrees with general relativity in many important cases, but possesses different gauge symmetries and constraints. Rather than…
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…
Parity Horizons in Shape Dynamics
Gabriel Herczeg
I introduce the notion of a parity horizon, and show that many simple solutions of shape dynamics possess them. I show that the event horizons of the known asymptotically flat blac…
Towards Black Hole Entropy in Shape Dynamics
Gabriel Herczeg, Vasudev Shyam
Shape dynamics is classical theory of gravity which agrees with general relativity in many important cases, but possesses different gauge symmetries and constraints. Rather than sp…
A Rotating Black Hole Solution for Shape Dynamics
Henrique Gomes, Gabriel Herczeg
Shape dynamics is a classical theory of gravity which agrees with general relativity in many important aspects, but which possesses different gauge symmetries and can present some…
