Entropy-Induced Phase Transitions in a Hidden Potts Model
Cook Hyun Kim, D. -S. Lee, B. Kahng
A hidden state in which a spin does not interact with any other spin contributes to the entropy of an interacting spin system. Using the Ginzburg-Landau formalism in the mean-field…
Energy-momentum uncertainties as possible origin of threshold anomalies in UHECR and TeV-gamma ray events
Y. Jack Ng, D. -S. Lee, M. C. Oh +1
A threshold anomaly refers to a theoretically expected energy threshold that is not observed experimentally. Here we offer an explanation of the threshold anomalies encountered in…
Real-time Nonequilibrium Dynamics in Hot QED Plasmas
Shang-Yung Wang
The quantum kinetics of photons is studied directly in real time by implementing the dynamical renormalization group. In contrast to conventional approach, the dynamical renormaliz…
Real-time nonequilibrium dynamics in hot QED plasmas: dynamical renormalization group approach
S. -Y. Wang, D. Boyanovsky, H. J. de Vega +1
We study the real-time nonequilibrium dynamics in hot QED plasmas implementing a dynamical renormalization group and using the hard thermal loop (HTL) approximation. The focus is o…
Damping Rates and Mean Free Paths of Soft Fermion Collective Excitations in a Hot Fermion-Gauge-Scalar Theory
S. -Y. Wang, D. Boyanovsky, H. J. de Vega +2
We study the transport coefficients, damping rates and mean free paths of soft fermion collective excitations in a hot fermion-gauge-scalar plasma with the goal of understanding th…
Chiral Symmetry Breaking in a Uniform External Magnetic Field
D. -S. Lee, C. N. Leung, Y. J. Ng
Using the nonperturbative Schwinger-Dyson equation, we show that chiral symmetry is dynamically broken in QED at weak couplings when an external magnetic field is present, and that…
