Nonperturbative Reduction of Yang-Mills Theory and Low Energy Effective Action
A. M. Khvedelidze, H. -P. Pavel
The method of reduction of a non-Abelian gauge theory to the corresponding unconstrained system is exemplified for SU(2) Yang-Mills field theory. The reduced Hamiltonian which desc…
Hamiltonian Reduction of SU(2) Yang-Mills Field Theory
A. M. Khvedelidze, H. -P. Pavel
The unconstrained system equivalent to SU(2) Yang-Mills field theory is obtained in the framework of the generalized Hamiltonian formalism using the method of Hamiltonian reduction…
On the Infrared Limit of Unconstrained SU(2) Yang-Mills Theory
A. M. Khvedelidze, H. -P. Pavel
The variables appropriate for the infrared limit of unconstrained SU(2) Yang-Mills field theory are obtained in the Hamiltonian formalism. It is shown how in the infrared limit an…
Coherent and squeezed condensates in massless theory
H. -P. Pavel, D. Blaschke, G. Roepke +1
Generalizing the Bogoliubov model of a weakly non-ideal Bose gas to massless theory we show that spontaneous breaking of symmetry occurs due to condensation in a coherent va…
