Berloff In the Hartree approximation, the equations governing the one particle wavefunction of the condensate, and the wave function of the electron, are a pair of coupled equations suggested by Gross [27] and by Clark [14] [15]: 5 5 (40) 6 5 (41) where and are the mass and single particle energy for the bosons; and are the mass and energy of the electron. The interaction ....

....range of the potential is important for vacancy migration as previously seen for SiC [8] We have also calculated the energy of divacancies both at 1st and 2nd neighbor positions. Little effect of potential is seen. The results for first neighbor binding are in reasonable agreement with experiment [20]. Recently Johnson [21] found that vacancy formation energies are significantly altered near a free surface in a 2D model EAM material. He found that the vacancy formation energy was reduced in the first layer, but increased in the second layer. We have investigated this effect for all four ....

....a classical point of view, equivalent to weak Konig s lemma, to be dealt with in section 7. Brouwer was able to prove the fan theorem using a principle of bar induction which he felt was justified by a constructive interpretation of the terms involved (cf. Beeson [1985] Troelstra and van Dalen [1988]) In a posthumous paper, C. Spector [1962] used a generalization of this principle to justify a computational scheme which he dubbed bar recursion. With this scheme Spector was able to provide a functional interpretation of full second order arithmetic, that is, the theory PA 2 (CA) defined ....

....If we have proved in Heytings arithmetic HA that E is an enumerator, then by Statmans result we can prove in Peano s arithmetic PA that E is reducing. The statement that a combinator is a reducing enumerator is Pi 0 2 . Therefore, by a well known result, see e.g. Troelstra and van Dalen [1988], proposition 3.3.5 (ii) it follows that also in HA one can prove that E is reducing. So the reader may wonder why we give an intuitionistic proof of Statmans theorem. The first reason is that there is a difference between knowing that a statement A can be proved intuitionistically and having an ....

....it before quoting the Lagrangians, to make the point that their field content, which at first sight may seem somewhat arbitrary, has a simple origin whose essence can be summarized fairly briefly. Given these fields, it has been shown that in each case there is a unique low energy Lagrangian [36]. 3.1 Spectrum of superstring theories The motion of a superstring world sheet is governed by a two dimensional quantum field theory, whose degrees of freedom always include a map embedding the world sheet into space time. A specific theory is characterized by the additional degrees of freedom ....

While the importance of two body currents for electromagnetic properties of nuclei is clearly established [1], the effect of two body currents inside baryons is not very well understood (see ref. 2] and refs. therein) In this respect, the striking agreement of the naive constituent quark model predictions for the octet baryon magnetic moments (summing up the magnetic moments of three free quarks gives ....

INTRODUCTION The phase behavior of adsorbed monolayers on a substrate has found longstanding interest [1], both experimental [2 4] as well as theoretical [5 14] Usually the theoretical description is done in the framework of lattice gas models, where the substrate is a fixed lattice with fixed adsorption sites which can either be occupied or empty. Such a model is equivalent to an Ising model, ....

Content based access to image databases has become an active area of research in recent years, but is still in its infancy. A sampling of recent work can be found in [1, 2]. The QUBIC project at IBM [3] is an example system that illustrates the state of the art in image retrieval by content, while examples of work in the area of geoscience databases include VIMSYS [4] and Sequoia 2000 [5] As part of a NASA HPCC Grand Challenge effort [Mun92] we have developed a ....
