A Nonlocal Realization of MOND that Interpolates from Cosmology to Gravitationally Bound Systems
C. Deffayet, R. P. Woodard
Nonlocal modifications of gravity derive from corrections to the quantum gravitational stress tensor which grow nonperturbatively strong during primordial inflation and may persist…
The Price of Abandoning Dark Matter Is Nonlocality
C. Deffayet, R. P. Woodard
We consider the classic question posed by Pardo and Spergel about the price of abandoning dark matter in the context of an invariant, metric-based theory of gravity. Our answer is…
Stable Vacua with Realistic Phenomenology and Cosmology in Heterotic M-theory Satisfying Swampland Conjectures
Cédric Deffayet, Burt A. Ovrut, Paul J. Steinhardt
We recently described a protocol for computing the potential energy in heterotic M-theory for the dilaton, complex structure and Kähler moduli. This included the leading order non-…
Moduli Axions, Stabilizing Moduli and the Large Field Swampland Conjecture in Heterotic M-Theory
Cédric Deffayet, Burt A. Ovrut, Paul J. Steinhardt
We compute the potential energy for the dilaton, complex structure and Kahler moduli and search of realistic vacua of heterotic M-theory compactified on Calabi-Yau threefolds. We p…
