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…
The Time Surface Term in Quantum Gravity
V. N. Pervushin, V. V. Papoyan, G. A. Gogilidze A. M. Khvedelidze +2
The role of the time surface term in the ADM Hamiltonian formulation of general relativity is investigated. We show that the variable contained in the time surface term (the scale…
Bogoliubov condensation of gluons and spontaneous gauge symmetry breaking in QCD
V. N. Pervushin, G. Roepke, M. K. Volkov +3
The problem of the gluonic quasiparticle excitations in QCD is considered under the aspect of the condensation of gluon pairs in the ''squeezed'' vacuum. The present approach is a…
On Admissible Gauges for Constrained Systems
S. A. Gogilidze, A. M. Khvedelidze, V. N. Pervushin
The {\it {gauge - fixing} } and {\it gaugeless } methods for reducing the phase space in the generalized Hamiltonian dynamics are compared with the aim to define the class of admis…
On Abelianization of First Class Constraints
S. A. Gogilidze, A. M. Khvedelidze, V. N. Pervushin
The systematic method for the conversion of first class constraints to the equivalent set of Abelian one based on the Dirac equivalence transformation is developed. The representat…
