DESCRIPTION:We allow a scalar field on a flat FLRW background metric to tu
 nnel between two degenerate minima. The resulting true vacuum state violat
 es the Null Energy Condition and the corresponding homogeneous fluid can i
 nduce a cosmological bounce when coupled to the Friedmann Equations. The m
 echanism presented here requires no exotic matter or modified gravity\, it
  is purely generated by quantum fluctuations and is valid for a generic do
 uble well potential.\n\nhttps://indico.ific.uv.es/event/6981/
