Smoothing and flattening the universe through slow contraction versus inflation
Anna Ijjas, Paul J. Steinhardt, David Garfinkle +1
In a systematic study, we use an equivalent pair of improved numerical relativity codes based on a tetrad-formulation of the classical Einstein-scalar field equations to examine wh…
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…
Cosmological Bounces Induced by a Fermion Condensate
Giorgi Tukhashvili, Paul J. Steinhardt
We show that it is possible for fermion condensation of the Nambu-Jona-Lasinio type to induce a non-singular bounce that smoothly connects a phase of slow contraction to a phase of…
Initial conditions problem in cosmological inflation revisited
David Garfinkle, Anna Ijjas, Paul J. Steinhardt
We present first results from a novel numerical relativity code based on a tetrad formulation of the Einstein-scalar field equations combined with recently introduced gauge/frame i…
Generating large disordered stealthy hyperuniform systems with ultra-high accuracy to determine their physical properties
Peter K. Morse, Jaeuk Kim, Paul J. Steinhardt +1
Hyperuniform many-particle systems are characterized by a structure factor that is precisely zero as ; and stealthy hyperuniform systems…
