An algorithm is described for the construction of actions for scalar, spinor, and vector gauge fields that remains well-defined when the metric is degenerate and that involve no contravariant tensor fields. These actions produce the standard matter dynamics and coupling to gravity when tetrad is nondegenerate, but have the property that all fields that appear in them can be pulled back through an arbitrary map of degree one and that this pull back leave the action invariant when the map has degree one.

  1. Bag-of-gold spacetimes, Euclidean wormholes, and inflation from domain walls in AdS/CFT

    hep-th 2019-09 conditional novelty 7.0 of 10

    Smooth Euclidean saddles with thin domain walls cannot create inflating interiors in AdS, but can create arbitrarily large bag-of-gold geometries at fixed black hole entropy.
