Prof. Atsuhisa Ota (Chongqing U)

7/31/25, 11:30 AM

We study stimulated emission and absorption of gravitons in a squeezed vacuum
state immersed in a thermal radiation bath. Employing one-loop
interaction-picture perturbation theory, we track the time evolution of the
graviton number operator and its expectation value in the squeezed vacuum,
which characterizes the inflationary graviton state. In a Minkowski background
with a thermal bath...
