Particle Exchange

Within the Hartree–Fock approximation the ground state of the composite fermion metal is found. We observe that the single-particle energy spectrum is dominated by the logarithmic interaction exchange term which leads to an infinite jump of the single-particle exchange at the Fermi momentum. It is shown that the Hartree–Fock result brings no corrections to the RPA Fermi velocity.

Values of the compressibility, cohesive energy, atomization energy, force constant, i.r. absorption frequency, Debye temperature, Griineisen parameter, Anderson-Griineisen parameter and MoelwynHughes parameter for 45 chalcogenide crystals with sodium chloride structure are reported here. These have been obtained using a logarithmic interaction potential energy function. A new method of calculation, derived on the basis of the Moelwyn-Hughes parameter, has been employed for the computation of the potential parameters, since previous methods cannot be applied to these crystals in the absence of compressibility data. The results obtained are encouraging.

We introduce and study a pure gauge Abelian theory in 2 + 1D in which massive quantum vortex states do exist in the spectrum of excitations. This theory can be mapped in a three-dimensional gas of point particles with a logarithmic interaction, in the grand-canonical ensemble. We claim that this theory is the 2 + 1D analog of the sine–Gordon, the massive vortices being the counterparts of sine–Gordon solitons. We show that a symmetry breaking, order parameter, similar to the vacuum expectation value of a Higgs field does exist.
