Higgs Inflation and the Electroweak Gauge Sector
Stephon Alexander, Cyril Creque-Sarbinowski, Humberto Gilmer +1
We introduce a new method that allows for the Higgs to be the inflaton. That is, we let the Higgs be a pseudo-Nambu-Goldstone (pNG) boson of a global coset symmetry that spon…
Spacetime geometry of acoustics and electromagnetism
Lucas Burns, Tatsuya Daniel, Stephon Alexander +1
Both acoustics and electromagnetism represent measurable fields in terms of dynamical potential fields. Electromagnetic force-fields form a spacetime bivector that is represented b…
The -axion and -axiverse of dark QCD
Stephon Alexander, Humberto Gilmer, Tucker Manton +1
Axions and axion-like particles (ALPs) are a prominent dark matter candidate, drawing motivation in part from the axiverse of string theory. Axion-like particles can also arise as…
A path integral formula of quantum gravity emergent from entangled local structures
Jinglong Liu, Stephon Alexander, Antonino Marciano +1
We couple to group field theory (GFT) a scalar field that encodes the entanglement between manifold sites. The scalar field provides a relational clock that enables the derivation…
Parity-Violating Trispectrum from Chern-Simons Gravity
Cyril Creque-Sarbinowski, Stephon Alexander, Marc Kamionkowski +1
We show that dynamical Chern-Simons (dCS) gravity imprints a parity-violating signal in primordial scalar perturbations. Specifically, we find that, after dCS amplifies one gravito…
de Sitter State in Heterotic String Theory
Stephon Alexander, Keshav Dasgupta, Archana Maji +2
Recent no-go theorems have ruled out four-dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well-defined Wilsonian effective act…
