Thermal Positivity
Clifford Cheung, Rachel A. Rosen
We argue that Lorentz invariance and unitarity impose sharp constraints on thermodynamic quantities. By relating thermal vacuum diagrams to forward scattering amplitudes, we derive…
On Entropy Bounds for Irrelevant Operators
Lucas Fernández-Sarmiento, Riccardo Penco, Rachel A Rosen
Consistency constraints for low-energy theories, especially those lacking Lorentz invariance, have recently garnered attention. Building on results from black hole thermodynamics,…
Applications of de Sitter Causality Conditions
Daniel McLoughlin, Rachel A Rosen
We find explicit de Sitter shockwave solutions in arbitrary spacetime dimensions. We use these to determine the dimensional-dependent "stretching" of the de Sitter Penrose diagram…
Cosmological gravitational particle production of massive spin-2 particles
Edward W. Kolb, Siyang Ling, Andrew J. Long +1
The phenomenon of cosmological gravitational particle production (CGPP) is expected to occur during the period of inflation and the transition into a hot big bang cosmology. Partic…
On Causality Conditions in de Sitter Spacetime
Noah Bittermann, Daniel McLoughlin, Rachel A. Rosen
We carefully consider the Shapiro time delay due to black holes and shockwaves in de Sitter spacetime and study the implications for causality. We discuss how causality conditions…
Gravitational Collapse in Massive Gravity on de Sitter Spacetime
Roman Berens, Luke Krauth, Rachel A. Rosen
We analyze the evolution of a homogenous and pressureless ball of dust (or "star") in ghost-free massive gravity on de Sitter spacetime. We find that gravitational collapse does no…
