Description
We investigated quantum infrared dynamics in 2D Liouville gravity
with a positive cosmological constant and a large central charge
$c>25$. Superhorizon fluctuations of the conformal mode of the
metric dynamically screen the cosmological constant, and the dS
entropy increases simultaneously. We can identify the dS entropy
with the von Neumann entropy of the conformal zero mode. This
quantum time evolution can also be described by a classical
inflation theory.
