Gaussian state for the bouncing quantum cosmology

Understand

We present results concerning propagation of the Gaussian state across the cosmological quantum bounce.

• The reduced phase space quantization of loop quantum cosmology is applied to the Friedman-Robertson-Walker universe with a free massless scalar field.
• Evolution of quantum moments of the canonical variables is investigated.
• The covariance turns out to be a monotonic function so it may be used as an evolution parameter having quantum origin.
