Chaos Driven by Soft-Hard Mode Coupling in Thermal Yang-Mills Theory

We argue on a basis of a simple few mode model of SU(2) Yang-Mills theory that the color off-diagonal coupling of the soft plasmon to hard thermal excitations of the gauge field drives the collective plasma oscillations into chaotic motion despite the presence of the plasmon mass.

Hard Thermal Effects in Noncommutative U(N) Yang-Mills Theory

We study the behaviour of the twoand three-point thermal Green functions, to one loop order in noncommutative U(N) Yang-Mills theory, at temperatures T much higher than the external momenta p. We evaluate the amplitudes for small and large values of the variable θ p T (θ is the noncommutative parameter) and exactly compute the static gluon self-energy for all values of θ p T . We show that thes...

Yang-Mills theory at finite coupling

Gauge theory-string theory duality describes strongly coupled N = 4 supersymmetric SU(nc) Yang-Mills theory at finite temperature in terms of near extremal black 3-brane geometry in type IIB string theory. We use this correspondence to compute the leading correction in inverse ’t Hooft coupling to the shear diffusion constant, bulk viscosity and the speed of sound in the large-nc N = 4 supersym...

Running coupling in Yang - Mills theory – a flow equation study –

The effective average action of Yang-Mills theory is analyzed in the framework of exact renormalization group flow equations. Employing the background-field method and using a cutoff that is adjusted to the spectral flow, the running of the gauge coupling is obtained on all scales. In four dimensions and for the gauge groups SU(2) and SU(3), the coupling approaches a fixed point in the infrared.

Gauge-invariant Soft Modes in Yang-mills Theory

A gauge-invariant saddle point expansion for the Yang-Mills vacuum transition amplitude on the basis of the squeezed approximation to the vacuum wave functional is outlined. This framework allows the identification of gauge-invariant infrared degrees of freedom which arise as dominant sets of gauge field orbits and provide the principal input for an essentially analytical treatment of soft ampl...
