# Oscillons from string moduli (movies)

## Oscillons from the Kähler modulus in the KKLT scenario

The movies below show the non-linear evolution of the Kähler modulus (and its energy density) in the KKLT scenario. The movies were created from three dimensional lattice simulations with 128 lattice points per dimension. Results from simulations with 256 and 512 points per dimension are presented and described in more detail in our paper "Oscillons from string moduli" arXiv:1708.08922 [hep-th].

## Field and energy density

Left: evolution of the Kähler modulus Φ(x,t) as the field oscillates around the minimum of the potential at Φ=Φmin The red areas correspond to field values Φ(x,t)-Φmin < 0 while blue areas denote Φ(x,t)-Φmin > 0. The minimum shown amplitude, denoted by the faintest colored areas, corresponds to |Φ(x,t)-Φmin|≥0.008 MPl while the largest highlighted amplitudes are  |Φ(x,t)-Φmin|≥0.04 MPl (brightest areas). Right: evolution of the energy density ρ(x,t) in units of  <ρ>. The yellow surfaces correspond to ρ(x,t)/<ρ> = 6 while the blue ones denote ρ(x,t)/<ρ> = 12. The movie was created from a three dimensional lattice simulation with 128 points per spatial dimension.

## Oscillons from blow-up moduli in the Large Volume Scenario (LVS)

The movies below were created from the results of two and three dimensional lattice simulations of the evolution of a blow-up Kähler modulus in the LVS in an expanding universe. More details on the models can be found in our paper "Oscillons from string moduli" arXiv:1708.08922 [hep-th].

## Field and energy density (2D)

The movie shows the time evolution of the blow-up Kähler modulus Φ(x,t) (left) and of its energy density ρ(x,t) (right) in two spatial dimensions. The energy density is shown in units of the average energy density <ρ>. The movie was created from a lattice simulation with 1024 points per spatial dimension.

## Energy density in 3D

Evolution of the energy density of the blow-up Kähler modulus. The yellow surfaces correspond to  ρ(x,t)/<ρ>=6 and the blue surfaces to ρ(x,t)/<ρ>=12, where <ρ> is the average energy density. The movie was created from a three dimensional lattice simulation with 128 points per spatial dimension.
