Gravitational wave constraints on non-birefringent dispersions of gravitational waves due to Lorentz violations with GWTC-3
Cheng Gong, Tao Zhu, Rui Niu +5
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry in the gravitational interaction. In…
Lyapunov Exponent and Plasmon Damping Rate in Nonabelian Gauge Theories
T. S. Biro, C. Gong, B. Mueller
We explain why the maximal positive Lyapunov exponent of classical SU() gauge theory coincides with (twice) the damping rate of a plasmon at rest in the leading order of thermal…
Renormalization Group Approach to Scalar Theory
Sen-Ben Liao, Chengqian Gong
Effective potential for scalar theory is obtained using the exact renormalization group method which includes both the usual one-loop contribution as well as the dominant hi…
Manifestation of Infrared Instabilities in High-Energy Processes in Nonabelian Gauge Theories
C. Gong, S. G. Matinyan, B. Mueller +1
We show that a high frequency standing wave in SU(2) gauge theory is unstable against decay into long wavelength modes. This provides a non-perturbative mechanism for energy transf…
Lyapunov Spectra in SU(2) Lattice Gauge Theory
C. Gong
We develop a method for calculating the Lyapunov characteristic exponents of lattice gauge theories. The complete Lyapunov spectrum of SU(2) gauge theory is obtained and Kolmogorov…
Some remarks on pion condensation in relativistic heavy ion collisions
C. Greiner, C. Gong, B. Müller
Recently it was pointed out that coherent or condensated states of pions may account for the explanation of the Centauro events observed in cosmic ray showers. We argue that an occ…
Hamiltonian Dynamics of Yang-Mills Fields on a Lattice
T. S. Biro, C. Gong, B. Mueller +1
We review recent results from studies of the dynamics of classical Yang-Mills fields on a lattice. We discuss the numerical techniques employed in solving the classical lattice Yan…
Variational Approach to Real-Time Evolution of Yang-Mills Gauge Fields on a Lattice
C. Gong, B. Mueller, T. S. Biro
Applying a variational method to a Gaussian wave ansatz, we have derived a set of semi-classical evolution equations for SU(2) lattice gauge fields, which take the classical form i…
Lyapunov Exponent of SU(3) Gauge Theory
C. Gong
The classical SU(3) gauge theory is shown to be deterministic chaotic. Its largest Lyapunov exponent is dertermined, from which a short time scale of thermalization of a pure gluon…
