External magnetic fields and the chiral phase transition in QED at nonzero chemical potential
W. -C. Syu, D. -S. Lee, C. N. Leung
Inspired by recent discussions of inverse magnetic catalysis in the literature, we examine the effects of a uniform external magnetic field on the chiral phase transition in quench…
Photon production from non-equilibrium disoriented chiral condensates in a longitudinal expansion : A theoretic framework
Da-Shin Lee, Yeo-Yie Charng, Kin-Wang Ng
A theoretical framework is developed for treating the quantization of the photons in a spacetime with a longitudinal expansion. This can be used to study the production of the phot…
Affleck-Dine Baryogenesis, Split Supersymmetry, and Inflation
Yeo-Yie Charng, Da-Shin Lee, Chung Ngoc Leung +1
It is shown that, in the context of split supersymmetry, a simple model with a single complex scalar field can produce chaotic inflation and generate the observed amount of baryon…
Nonequilibrium Effects and Baryogenesis
Yeo-Yie Charng, Da-Shin Lee, Chung Ngoc Leung +1
Possible effects due to nonequilibrium dynamics in the Affleck-Dine mechanism of baryogenesis are examined. Using the closed-time-path formalism, the quantum fluctuation and the ba…
Photon Production from Nonequilibrium Disoriented Chiral Condensates in a Spherical Expansion
Yeo-Yie Charng, Kin-Wang Ng, Chi-Yong Lin +1
We study the production of photons through the non-equilibrium relaxation of a disoriented chiral condensate formed in the expanding hot central region in ultra-relativistic heavy-…
Out-of-equilibrium Photon Production from Disoriented Chiral Condensates
Da-Shin Lee, Kin-Wang Ng
We study the production of photons through the non-equilibrium relaxation of a disoriented chiral condensate. We propose that to search for non-equilibrium photons in the direct ph…
