Obstruction to local entropy laws on arbitrary black-hole cuts in five-dimensional Einstein--Gauss--Bonnet gravity
Cendikiawan Suryaatmadja, Robert B. Mann
We study local entropy laws on arbitrary cuts of event horizons in five-dimensional Einstein--Gauss--Bonnet gravity, treated as an exact theory. No covariant local entropy can both…
Charged soliton--black hole phase transitions in three-dimensional Einstein--Gauss--Bonnet gravity
Cendikiawan Suryaatmadja, Robert Mann
We construct a magnetic soliton by double Wick rotating the static electrically charged black hole in three-dimensional Einstein--Gauss--Bonnet gravity. We match the boundary metri…
Propagation and horizon formation in Einstein--Gauss--Bonnet scalar collapse. I. Characteristic conditions, bounds and formation
Cendikiawan Suryaatmadja
We study scalar collapse in five- and six-dimensional Einstein--Gauss--Bonnet gravity with positive coupling, treated as an exact classical theory. On spherical scalar backgrounds,…
Black Holes and Scalar Propagation in Three-Dimensional Einstein--Gauss--Bonnet Gravity
Cendikiawan Suryaatmadja
We derive an analytic black-hole family in three-dimensional scalar--tensor Einstein--Gauss--Bonnet gravity with positive coupling. A single implicit equation determines the static…
Acceleration in 3D Einstein-Gauss-Bonnet Gravity
Cendikiawan Suryaatmadja, Dong-han Yeom, Robert Mann
We present a new class of exact solutions in Einstein-Gauss-Bonnet gravity in 2+1 dimensions that generalize the C-metric. This set of metrics equals the C-metric multiplied by a f…
Signatures of Rotating Black Holes in Quantum Superposition
Cendikiawan Suryaatmadja, Cemile Senem Arabaci, Matthew P. G. Robbins +3
A new approach for operationally studying the effects of spacetime in quantum superpositions of semiclassical states has recently been proposed by some of the authors. This approac…
Relativity and decoherence of spacetime superpositions
Joshua Foo, Robert B. Mann, Magdalena Zych
It is univocally anticipated that in a theory of quantum gravity, there exist quantum superpositions of semiclassical states of spacetime geometry. Such states could arise for exam…
Entanglement Harvesting of Inertially Moving Unruh-DeWitt Detectors in Minkowski Spacetime
Cendikiawan Suryaatmadja, Wan Cong, Robert . B. Mann
We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent and constant velocitie…
