Real-time Gravitational Wave Response in Thermal Spinning fields
Atsuhisa Ota, Hui-Yu Zhu, Yuhang Zhu
We study how the spin content of the thermal plasmas affects the propagation of gravitational waves in a radiation-dominated universe. As a simple but representative setup, we cons…

Graviton stimulated emission in squeezed vacuum states
Atsuhisa Ota, Yuhang Zhu
We study the dynamics of gravitons in a squeezed vacuum state under a thermal radiation background. Unlike traditional treatments that rely on the Boltzmann equation, we employ the…

Missing one-loop contributions in secondary gravitational waves
Chao Chen, Atsuhisa Ota, Hui-Yu Zhu +1
We find several missing one-loop-order contributions in previous considerations about secondary gravitational waves induced at nonlinear order in cosmological perturbations. We con…
