Thermal Damping of Mass-Modulating Scalars
Abhishek Banerjee, Ngan H. Nguyen, Erwin H. Tanin
The cosmological evolution of a scalar field is shaped by Hubble damping. Any non-gravitational couplings of the scalar with the primordial thermal bath generically contribute addi…

Thermal Damping of Neutrino-Coupled Scalar Dark Matter
Abhishek Banerjee, Ngan H. Nguyen, Erwin H. Tanin
We point out that ultralight scalar dark matter that modulates neutrino masses can be significantly thermal damped by cosmic neutrinos in the early universe. This dissipative effec…
