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…

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…

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…
