Gauge Fixing in the Chain by Chain Method
In a recent work we showed that for a Hamiltonian system with constraints, the set of constraints can be investigated in first and second class constraint chains. We show here that using this ”chain by chain” method for an arbitrary system one can fix the gauges in the most economical and consistent way. We show that it is enough to assume some gauge fixing conditions conjugate to last elements...
متن کاملRabies vaccine stockpile: fixing the supply chain
635 World Rabies Day is 28 September, 2016,1 and is designed to raise awareness about the prevention and control of this neglected disease. Almost all human rabies are transmitted by domestic dog bites or scratches, usually via saliva. Rabies virus replicates in the wound site and gains access to nerves to reach the central nervous system. The incubation period varies from five days to several ...
متن کاملClassification of constraints using chain by chain method 1
Using our " chain by chain " method for constructing the constraint structure of a system possessing both first and second class constraints, we show that the whole constraints can be classified into completely first or second class constraint chains. We found appropriate redefini-tion of second class constraints so that to obtain a symplectic algebra among them.
متن کاملCalculation of chemical potentials of chain molecules by the incremental gauge cell method.
The gauge cell Monte Carlo method is extended to calculations of the incremental chemical potentials and free energies of linear chain molecules. The method was applied to chains of Lennard-Jones beads with stiff harmonic bonds up to 500 monomers in length. We show that the suggested method quantitatively reproduces the modified Widom particle insertion method of Kumar et al. [S. K. Kumar, I. S...
متن کاملGauge fixing by unitary transformations in QCD
The unitary gauge fixing technique is applied to the QCD hamiltonian formulated in terms of angular variables. It is demonstrated that in this formulation projections on the physical Hilbert space are unnecessary to separate physical and unphysical degrees of freedom. Therefore the application of the unitary gauge fixing technique can be extended to the operator level.
