    We compute the quantum circuit complexity of the evolution of scalar curvature perturbations on expanding backgrounds, using the language of squeezed vacuum states. In particular, we construct a simple cosmological model ...
  • Bhattacharya, Arpan; Das, Saurya; Haque, S. Shajidul; Underwood, Bret (American Physical Society, 2020-08)
    We compute the circuit complexity of scalar curvature perturbations on Friedmann-Lemaitre-Robertson-Walker cosmological backgrounds with a fixed equation of state w using the language of squeezed vacuum states. Backgrounds ...
