Misalignment dynamics of Scalar Condensates with Yukawa coupling: Particle and Entropy Production
Nathan Herring, Daniel Boyanovsky
Misalignment dynamics, the non-equilibrium evolution of a scalar (or pseudoscalar) condensate in a potential landscape, broadly describes a solution to the strong CP problem, a mec…
Is the finite temperature effective potential, effective for dynamics?
Nathan Herring, Shuyang Cao, Daniel Boyanovsky
We study the applicability of the finite temperature effective potential in the equation of motion of a homogeneous "misaligned" scalar condensate , and find important caveats t…
Is the effective potential, effective for dynamics?
Nathan Herring, Shuyang Cao, Daniel Boyanovsky
We critically examine the applicability of the effective potential within dynamical situations and find, in short, that the answer is negative. An important caveat of the use of an…
Gravitational production of nearly thermal fermionic Dark Matter
Nathan Herring, Daniel Boyanovsky
We consider the cosmological production of fermionic dark matter during inflation and a post-inflationary radiation dominated era. This fermion \emph{only interacts gravitationally…
Non-adiabatic cosmological production of ultra-light Dark Matter
Nathan Herring, Daniel Boyanovsky, Andrew R. Zentner
We study the non-adiabatic cosmological production of ultra light dark matter (ULDM) under a minimal set of assumptions: a free ultra light real scalar as a spectator field in its…
Cosmological decay of Higgs-like scalars into a fermion channel
Daniel Boyanovsky, Nathan Herring
We study the decay of a Higgs-like scalar Yukawa coupled to massless fermions in post-inflationary cosmology, combining a non-perturbative method with an adiabatic expansion. The r…
