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…
Condensate decay in a radiation dominated cosmology
Shuyang Cao, Daniel Boyanovsky
We study the decay of a homogeneous condensate of a massive scalar field of mass \emph{m} into massless fields in thermal equilibrium in a radiation dominated cosmology. The model…
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…
Effective field theory of particle mixing
Shuyang Cao, Daniel Boyanovsky
We introduce an effective field theory to study \emph{indirect} mixing of two fields induced by their couplings to a common decay channel in a medium. The extension of the method o…
Chern Simons condensate from misaligned axions
Shuyang Cao, Daniel Boyanovsky
We obtain the non-equilibrium condensate of the Chern Simons density induced by a misaligned homogeneous coherent axion field in linear response. The Chern-Simons dynamical suscept…
