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…
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…
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…
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…
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…
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…
