Ab-initio QCD Calculations Impact the Inference of the Neutron-star-matter Equation of State
(Peer reviewed; Journal article, 2023)We demonstrate that ab-initio calculations in QCD at high densities offer significant and nontrivial information about the equation of state of matter in the cores of neutron stars, going beyond that which is obtainable ... -
Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory
(Journal article; Peer reviewed, 2017-02)John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ... -
Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model
(Journal article; Peer reviewed, 2018-11)We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ... -
Universal Black Holes
(Peer reviewed; Journal article, 2020-02)We prove that a generalized Schwarzschild-like ansatz can be consistently employed to construct d-dimensional static vacuum black hole solutions in any metric theory of gravity for which the Lagrangian is a scalar invariant ... -
Unveiling the gravitational universe at μ-Hz frequencies
(Peer reviewed; Journal article, 2021)We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in between the Laser Interferometer Space Antenna ...
