Correlated Fluctuations in Luminosity Distance and the (Surprising) Importance of Peculiar Motion in Supernova Surveys
Lam Hui, Patrick B. Greene
Large scale structure introduces two different kinds of errors in the luminosity distance estimates from standardizable candles such as supernovae Ia (SNe) - a Poissonian scatter f…
Spinors, Inflation, and Non-Singular Cyclic Cosmologies
C. Armendariz-Picon, Patrick B. Greene
We consider toy cosmological models in which a classical, homogeneous, spinor field provides a dominant or sub-dominant contribution to the energy-momentum tensor of a flat Friedma…
Everpresent Lambda
Maqbool Ahmed, Scott Dodelson, Patrick B. Greene +1
A variety of observations indicate that the universe is dominated by dark energy with negative pressure, one possibility for which is a cosmological constant. If the dark energy is…
Supergravity Inflation Free from Harmful Relics
Patrick B. Greene, Kenji Kadota, Hitoshi Murayama
We present a realistic supergravity inflation model which is free from the overproduction of potentially dangerous relics in cosmology, namely moduli and gravitinos which can lead…
Dynamics of Symmetry Breaking and Tachyonic Preheating
Gary Felder, Juan Garcia-Bellido, Patrick B. Greene +3
We reconsider the old problem of the dynamics of spontaneous symmetry breaking using 3d lattice simulations, and develop a theory of tachyonic preheating, which occurs due to the s…
On the Theory of Fermionic Preheating
Patrick B. Greene, Lev Kofman
In inflationary cosmology, the particles constituting the Universe are created after inflation due to their interaction with moving inflaton field(s) in the process of preheating.…
Inflationary Reheating and Fermions
Patrick B. Greene
Coherent oscillations of the inflaton field at the end of inflation can parametrically excite fermions in much the same way that bosons are created in preheating. Although Pauli-bl…
Sine-Gordon Parametric Resonance
Patrick B. Greene, Lev Kofman, Alexei A. Starobinsky
We consider the instability of fluctuations in an oscillating scalar field which obeys the Sine-Gordon equation. We present simple closed-form analytic solutions describing the par…
Preheating of Fermions
Patrick B. Greene, Lev Kofman
In inflationary cosmology, the particles constituting the Universe are created after inflation in the process of reheating due to their interaction with the oscillating inflaton fi…
Structure of Resonance in Preheating after Inflation
Patrick Greene, Lev Kofman, Andrei Linde +1
We consider preheating in the theory , where the classical oscillating inflaton field decays into -particles and -particles. The parametric res…
