The effective potential of composite fields in weakly coupled QED in a uniform external magnetic field
D. -S. Lee, P. N. McGraw, Y. J. Ng +1
The effective potential for the composite fields responsible for chiral symmetry breaking in weakly coupled QED in a magnetic field is derived. The global minimum of the effective…
Fermion Damping in a Fermion-Scalar Plasma
D. Boyanovsky, H. J. de Vega, Y. J. Ng +2
In this article we study the dynamics of fermions in a fermion-scalar plasma. We begin by obtaining the effective in-medium Dirac equation in real time which is fully renormalized…
Cosmic Background Radiation Temperature Anisotropy: Position of First Doppler Peak
Paul H. Frampton, Y. Jack Ng, Ryan Rohm
The purpose of the Cosmic Background Radiation (CBR) experiments is to measure the temperature anisotropy via the autocorrelation function. The partial wave corresponding to…
Magnetic catalysis of chiral symmetry breaking and the Pauli problem
Y. Jack Ng
The non-perturbative Schwinger-Dyson equation is used to show that chiral symmetry is dynamically broken in QED at weak gauge couplings when an external uniform magnetic field is p…
