Model-dependent analysis method for energy budget of the cosmological first-order phase transition
Xiao Wang, Chi Tian, Fa Peng Huang
The kinetic energy of the fluid shell in the cosmological first-order phase transition is crucial for predicting the gravitational wave signals generated by the sound wave mechanis…
Accelerating spherical harmonic transforms for a large number of sky maps
Chi Tian, Siyu Li, Hao Liu
The spherical harmonic transform is a powerful tool in the analysis of spherical data sets, such as the cosmic microwave background data. In this work, we present a new scheme for…
What is flat ΛCDM, and may we choose it?
Stefano Anselmi, Matthew F. Carney, John T. Giblin +5
The Universe is neither homogeneous nor isotropic, but it is close enough that we can reasonably approximate it as such on suitably large scales. The inflationary--Cold Dark Mat…
Gravitational Waves from Fully General Relativistic Oscillon Preheating
Xiao-Xiao Kou, James B. Mertens, Chi Tian +1
As long-lived quasi-solitons from the fragmentation of a scalar condensate, oscillons may dominate the preheating era after inflation. During this period, stochastic gravitational…
Accurate relativistic observables from post-processing light cone catalogues
Chi Tian, Matthew F. Carney, James B. Mertens +1
We introduce and study a new scheme to construct relativistic observables from post-processing light cone data. This construction is based on a novel approach, LC-Metric, which tak…
On the question of measuring spatial curvature in an inhomogeneous universe
Chi Tian, Stefano Anselmi, Matthew F. Carney +3
The curvature of a spacetime, either in a topological sense, or averaged over super-horizon-sized patches, is often equated with the global curvature term that appears in Friedmann…
Oscillon Preheating in Full General Relativity
Xiao-Xiao Kou, Chi Tian, Shuang-Yong Zhou
Oscillons are dense objects that may be copiously produced in the preheating period after inflation, during which what role general relativity might play is largely unknown. We inv…
Cosmic expansion from spinning black holes
John T. Giblin, James B. Mertens, Glenn D. Starkman +1
We examine how cosmological expansion arises in a universe containing a lattice of spinning black holes. We study averaged expansion properties as a function of fundamental propert…
The Limited Accuracy of Linearized Gravity
John T. Giblin, James B. Mertens, Glenn D. Starkman +1
Standard cosmological models rely on an approximate treatment of gravity, utilizing solutions of the linearized Einstein equations as well as physical approximations. In an era of…
The Supersymmetric Standard Models with a Pseudo-Dirac Gluino from Hybrid and Term Supersymmetry Breakings
Ran Ding, Tianjun Li, Florian Staub +2
We propose the Supersymmetric Standard Models (SSMs) with a pseudo-Dirac gluino from hybrid and term supersymmetry (SUSY) breakings. Similar to the SSMs before the LHC, al…
Effect of the Minimal Length on Bose-Einstein Condensation in the Relativistic Ideal Bose Gas
Xiuming Zhang, Chi Tian
Based on the generalized uncertainty principle (GUP), the critical temperature and the Helmholtz free energy of Bose-Einstein condensation (BEC) in the relativistic ideal Bose gas…
The Renormalizable Three-Term Polynomial Inflation with Large Tensor-to-Scalar Ratio
Tianjun Li, Zheng Sun, Chi Tian +1
We systematically study the renormalizable three-term polynomial inflation in the supersymmetric and non-supersymmetric models. The supersymmetric inflaton potentials can be realiz…
