We study the Coulombic criticality of ionic fluids within the restricted primitive model (RPM).We indicate that for the RPM, analysed in terms of the field of charge density, the corresponding LandauGinzburg-Wilson effective Hamiltonian has a negative φ4-coefficient. In that case, solving the “exact” renormalization group equation in the local potential approximation, we show that close initial...

The relativistic correction to the QCD static interquark potential at O(1/m) is investigated nonperturbatively for the first time by using lattice Monte Carlo QCD simulations. The correction is found to be comparable with the Coulombic term of the static potential when applied to charmonium, and amounts to one-fourth of the Coulombic term for bottomonium.

Using a classical trajectory Monte Carlo method, we have computed the ionization resulting from the interaction between two cold Rydberg atoms. We focus on the products resulting from close interaction between two highly excited atoms. We give information on the distribution of ejected electron energies, the distribution of internal atom energies and the velocity distribution of the atoms and i...

The interaction of quarkonium with nuclei is studied in the mQ → ∞ limit of QCD, where the binding energy is found to be exactly computable. The dominant contribution to the interaction is from two-gluon operators. The forward matrix elements of these twogluon operators can be determined from the QCD scale anomaly, and from deep inelastic scattering. We apply our results to the Υ and J/ψ, treat...

1. Some mucus glycoproteins form soluble complexes with lysozyme at neutral pH values. 2. The extent of complex-formation was determined, by an ultracentrifugal difference method, for a range of glycoproteins covering the common blood-group specificities. 3. Interaction was strongest with those glycoproteins of blood-group Lea specificity; these were also richest in sialic acid. 4. Interaction ...
