Towards the theory of reheating after inflation

- L. Kofman, Andrei Linde, A. Starobinsky
- Physics
- 30 April 1997

Reheating after inflation occurs due to particle production by the oscillating inflaton field. In this paper we describe the perturbative approach to reheating, and then concentrate on effects beyond… Expand

Structure of resonance in preheating after inflation

- P. B. Greene, L. Kofman, Andrei Linde, A. Starobinsky
- Mathematics, Physics
- 19 May 1997

We consider preheating in the theory $1/4 \lambda \phi^4 + 1/2 g^2\phi^2\chi^2 $, where the classical oscillating inflaton field $\phi$ decays into $\chi$-particles and $\phi$-particles. The… Expand

How filaments of galaxies are woven into the cosmic web

- J. Bond, L. Kofman, D. Pogosyan
- PhysicsNature
- 21 December 1995

LARGE-SCALE structure in the distribution of galaxies is thought to have evolved through gravitational instabilities from small density fluctuations in the (largely homogeneous) early Universe. This… Expand

Instant Preheating

- G. Felder, L. Kofman, Andrei Linde
- Physics
- 9 December 1998

We describe a new efficient mechanism of reheating. Immediately after rolling down the rapidly moving inflaton field $\phi$ produces particles $\chi$, which may be either bosons or fermions. This is… Expand

Beauty is attractive: Moduli trapping at enhanced symmetry points

- L. Kofman, Andrei Linde, Xiao Liu, A. Maloney, L. McAllister, E. Silverstein
- Physics
- 1 March 2004

We study quantum effects on moduli dynamics arising from the production of particles which are light at points of enhanced symmetry in moduli space. The resulting forces trap the moduli at these… Expand

Suppressing the lower multipoles in the CMB anisotropies

- C. Contaldi, M. Peloso, L. Kofman, Andrei Linde
- Physics
- 31 March 2003

The Cosmic Microwave Background (CMB) anisotropy power on the largest angular scales observed both by WMAP and COBE DMR appears to be lower than the one predicted by the standard model of cosmology… Expand

Superconformal symmetry, supergravity and cosmology

- R. Kallosh, L. Kofman, Andrei Linde, A. Proeyen
- Physics
- 22 June 2000

We introduce the general N = 1 gauge theory superconformally coupled to supergravity. The theory has local SU(2,2|1) symmetry and no dimensional parameters. The superconformal origin of the… Expand

Preheating with trilinear interactions: Tachyonic resonance

- J. Dufaux, G. Felder, L. Kofman, M. Peloso, D. Podolsky
- Physics
- 16 February 2006

We investigate the effects of bosonic trilinear interactions in preheating after chaotic inflation. A trilinear interaction term allows for the complete decay of the massive inflaton particles, which… Expand

Evolution of one-point distributions from Gaussian initial fluctuations

- L. Kofman, E. Bertschinger, J. M. Gelb, A. Nusser, A. Dekel
- Physics
- 11 November 1993

We study the quasilinear evolution of the one-point probability density functions (PDFs) of the smoothed density and velocity fields in a cosmological gravitating system beginning with Gaussian… Expand

Tachyonic instability and dynamics of spontaneous symmetry breaking

- G. Felder, L. Kofman, Andrei Linde
- Materials Science
- 19 June 2001

Spontaneous symmetry breaking usually occurs due to the tachyonic (spinodal) instability of a scalar field near the top of its effective potential at $\ensuremath{\varphi}=0.$ Naively, one might… Expand
