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…
Is there a maximum magnetic field in QED?
Chung Ngoc Leung, Shang-Yung Wang
It was recently conjectured by Shabad and Usov that there exists in QED a maximum magnetic field of 10^{42} G, above which the magnetized vacuum becomes unstable. Using a nonpertur…
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…
Probing the Gravitational Scale via Running Gauge Couplings
Ilia Gogoladze, C. N. Leung
According to a recent paper by Robinson and Wilczek, the leading gravitational corrections to the running of gauge couplings tend to reduce the values of the couplings at energies…
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…
Gauge Independence and Chiral Symmetry Breaking in a Strong Magnetic Field
C. N. Leung, S. -Y. Wang
The gauge independence of the dynamical fermion mass generated through chiral symmetry breaking in QED in a strong, constant external magnetic field is critically examined. We pres…
