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…
