Title: Gravitational waves from asymmetric oscillon dynamics?

Abstract

It has been recently suggested that oscillons produced in the early universe from certain asymmetric potentials continue to emit gravitational waves for a number of e-folds of expansion after their formation, leading to potentially detectable gravitational wave signals. We revisit this claim by conducting a convergence study using graphics processing unit (GPU)-accelerated lattice simulations and show that numerical errors accumulated with time are significant in low-resolution scenarios, or in scenarios where the run-time causes the resolution to drop below the relevant scales in the problem. Our study determines that the dominant, growing high frequency peak of the gravitational wave signals in the fiducial "hill-top model" in [arXiv:1607.01314] is a numerical artifact. This new finding prompts the need for a more careful analysis of the numerical validity of other similar results related to gravitational waves from oscillon dynamics.

Gravitational perturbations from oscillons and transients after inflation

Journal Article Lozanov, Kaloian D. ; Amin, Mustafa A. - Physical Review D

We study the scalar and tensor perturbations generated by the fragmentation of the inflaton condensate into oscillons or transients after inflation, using nonlinear classical lattice simulations. Without including the backreaction of metric perturbations, we find that the magnitude of scalar metric perturbations never exceeds a few ×10^-3, whereas the maximal strength of the gravitational wave signal today is $O$(10^-9) for standard post-inflationary expansion histories. We provide parameter scalings for the α-attractor models of inflation, which can be easily applied to other models. We also discuss the likelihood of primordial black hole formation, as well as conditions under which the gravitationalmore »« less

Self-resonance after inflation: Oscillons, transients, and radiation domination

Journal Article Lozanov, Kaloian D. ; Amin, Mustafa A. - Physical Review D

Homogeneous oscillations of the inflaton after inflation can be unstable to small spatial perturbations even without coupling to other fields. We show that for inflaton potentials ∝Φ|²ⁿ near |Φ|=0 and flatter beyond some |Φ|=M, the inflaton condensate oscillations can lead to self-resonance, followed by its complete fragmentation. We find that for non-quadratic minima (n>1), shortly after backreaction, the equation of state parameter, w→1/3. If M << m_Pl, radiation domination is established within less than an e-fold of expansion after the end of inflation. In this case self-resonance is efficient and the condensate fragments into transient, localised spherical objects which aremore »« less

A review of the discovery reach of directional Dark Matter detection

Journal Article Mayet, F. ; Green, A. M. ; Battat, J. B. R. ; ... - Physics Reports

Cosmological observations indicate that most of the matter in the Universe is Dark Matter. Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs) can be detected directly, via its elastic scattering off target nuclei. Most current direct detection experiments only measure the energy of the recoiling nuclei. However, directional detection experiments are sensitive to the direction of the nuclear recoil as well. Due to the Sun's motion with respect to the Galactic rest frame, the directional recoil rate has a dipole feature, peaking around the direction of the Solar motion. This provides a powerful tool for demonstrating themore »« less

Adiabatic hydrodynamics: the eightfold way to dissipation

Journal Article Haehl, Felix M. ; Loganayagam, R. ; Rangamani, Mukund - Journal of High Energy Physics (Online)

Hydrodynamics is the low-energy effective field theory of any interacting quantum theory, capturing the long-wavelength fluctuations of an equilibrium Gibbs densitymatrix. Conventionally, one views the effective dynamics in terms of the conserved currents, which should be expressed via the constitutive relations in terms of the fluid velocity and the intensive parameters such as the temperature, chemical potential, etc. . . However, not all constitutive relations are acceptable, one has to ensure that the second law of thermodynamics is satisfied on all physical configurations. In this paper, we provide a complete solution to hydrodynamic transport at all orders in the gradientmore »« less

Machine Learning for Searching the Dark Energy Survey for Trans-Neptunian Objects

Journal Article Henghes, B. ; Lahav, O. ; Gerdes, D. W. ; ... - Publications of the Astronomical Society of the Pacific (Online)

In this paper we investigate how implementing machine learning could improve the efficiency of the search for Trans-Neptunian Objects (TNOs) within Dark Energy Survey (DES) data when used alongside orbit fitting. The discovery of multiple TNOs that appear to show a similarity in their orbital parameters has led to the suggestion that one or more undetected planets, an as yet undiscovered "Planet 9", may be present in the outer solar system. DES is well placed to detect such a planet and has already been used to discover many other TNOs. Within, we perform tests on eight different supervised machine learningmore »« less
