Bootstrapping Weakly Broken Gauge Theories in (A)dS
Daniel Baumann, Kurt Hinterbichler, Callum R. T. Jones +1
We develop a bootstrap approach for weakly broken gauge theories in (anti-)de Sitter space, focusing on cases in which the conservation of the dual boundary current is broken by a…
Breaking de Sitter Symmetry with Cosmic Topology: Cosmological Role of Infrared Vacuum Freedom
Anna Negro, Kurt Hinterbichler, Glenn D. Starkman +5
When spatial sections of spacetime are topologically nontrivial, the symmetry arguments usually used to choose the Bunch-Davies vacuum are no longer guaranteed to apply. We study t…
Moduli Bounds from Spin-2 Sum Rules
Francesco Bertucci, James Bonifacio, Kurt Hinterbichler
Mirbabayi and Villadoro have provided strong numerical evidence for a universal upper bound on the mass of the lightest scalar field in gravitational Kaluza--Klein (KK) theories. T…
Radial Solutions of Multi-Field de Sitter Galileons
Alice Garoffolo, Mary Gerhardinger, Kurt Hinterbichler +1
We study static, spherically symmetric screening solutions in the -invariant multi-field de Sitter Galileon theory, with matter couplings preserving the internal…
De Sitter Representations
Kurt Hinterbichler
We review the representations of so(1,D), the algebra of isometries of D dimensional de Sitter space. We cover the representations in all D, including mixed symmetry representation…
Quantum Signatures of Cosmic Topology: How Casimir Backreaction Transmits Isotropy Violation
Anna Negro, Kurt Hinterbichler, Glenn D. Starkman +17
A finite, scheme-independent Casimir contribution to the stress-energy tensor arises naturally for quantum fields in universes with non-trivial spatial topology. We compute this Ca…
