An analytic evaluation of gravitational particle production of fermions via Stokes phenomenon
Soichiro Hashiba, Siyang Ling, Andrew J. Long
The phenomenon of gravitational particle production can take place for quantum fields in curved spacetime. The abundance and energy spectrum of gravitationally produced particles i…
Stokes phenomenon and gravitational particle production -- How to evaluate it in practice
Soichiro Hashiba, Yusuke Yamada
We revisit gravitational particle production from the Stokes phenomenon viewpoint, which helps us make a systematic way to understand asymptotic behavior of mode functions in time-…
Particle production induced by vacuum decay in real time dynamics
Soichiro Hashiba, Yusuke Yamada, Jun'ichi Yokoyama
We discuss particle production associated with vacuum decay, which changes the mass of a scalar field coupled to a background field which induces the decay. By utilizing the Stokes…
