Use of a microcomputer with the multiple exposure photography (MEP) method for rapid analysis of semen characteristics is described. The computer is programmed to calculate information fed from a… (More)

Recently, a type of null experiment for spacelike neutrinos has been proposed. We examine in detail a class of null tests involving nuclear beta decay or capture in atoms and ions. The most promising… (More)

We consider deformations of the singular “global cosmic string” compactifications, known to naturally generate exponentially large scales. The deformations are obtained by allowing a constant… (More)

The phenomenon of sonoluminescence (SL), originally observed some sixty years ago, [1] has recently become the focus of renewed interest, [2]-[9] particularly with the discovery that one can trap a… (More)

Standard discussions of Goldstone’s theorem based on a symmetry of the action assume constant fields and global transformations, i.e., transformations which are independent of spacetime coordinates.… (More)

We study symmetry breaking in the static coordinate-system of de Sitter space. This is done with the help of the functional-Schrödinger approach used in previous calculations by Ratra [1]. We… (More)

We compute the 1/N correction to the location of the previously found first-order phase transition in the Gross-Neveu model at a chemical potential μ = μc = 1 √ 2 m, where m is the fermion mass. We… (More)

A formalism is developed to enable the construction of the effective action and related quantities in QED for the case of time-varying background electric fields. Some examples are studied and… (More)

We study a 2-dimensional model of fermi fields ψ that is closely related to the GrossNeveu model, and show that to leading order in 1 N a 〈ψψ〉 condensate forms. This effect is independent of the… (More)
