Staggered-flux normal state in the weakly doped t-J model

A normal (non-superconducting) ground state of the t-J model may be variationally approximated by a Gutzwiller-projected wave function. Within this approximation, at small hole doping near half-filling, the normal state favors staggered-flux ordering. Such a staggered-flux state may occur in vortex cores of underdoped high-temperature cuprate superconductors. From comparing the energies of the staggered-flux state and of the superconducting state, we numerically obtain the condensation energy. Extracting the superfluid density directly from the projected superconducting wave function, we can also estimate the coherence length at zero temperature.Comment: 5 pages, 4 figure

Novartis and the United Nations Global Compact Initiative

The spirit of the Global Compact found fertile ground and has become an integral part of Novartis corporate strategy since the enterprise was formed by the merger of the two large Swiss pharmaceutical companies, Sandoz and Ciba, in 1996. Following a four-year concentration on economic consolidation and performance, Daniel Vasella (Chairman and CEO) signed the Global Compact. Together, productivity-based economic performance and a proactive approach to the expectations of society are envisioned as the key to long-term corporate success in the rapidly integrating global economic, political, and social environment of today’s large multinational corporation. This paper outlines the Novartis strategy and its implementation including the coalescing role of the Global Compact in the drive for sustainable corporate development. Following a review of extending corporate strategy to incorporate social concerns into the economic business model, the process of implementing the strategy will be assessed. In part three, specific examples of this strategic positioning will be outlined.http://deepblue.lib.umich.edu/bitstream/2027.42/39911/3/wp526.pd

Computer program MCAP-TOSS calculates steady-state fluid dynamics of coolant in parallel channels and temperature distribution in surrounding heat-generating solid

Computer program calculates the steady state fluid distribution, temperature rise, and pressure drop of a coolant, the material temperature distribution of a heat generating solid, and the heat flux distributions at the fluid-solid interfaces. It performs the necessary iterations automatically within the computer, in one machine run

A Possible Origin of Dark Energy

We discuss the possibility that the existence of dark energy may be due to the presence of a spin zero field $\phi(x)$, either elementary or composite. In the presence of other matter field, the transformation $\phi(x)\to \phi(x) +$ constant can generate a negative pressure, like the cosmological constant. In this picture, our universe can be thought as a very large bag, similar to the much smaller MIT bag model for a single nucleon.Comment: 4 pages, no figure, typos correcte

Professionalism Under Fire: Canadian Implementation of the Medak Pocket Agreement, Croatia 1993

For many Canadians, the Somalia Affair became a symbol of their armed forces in the 1990s. Intense media coverage of a Somali teen’s murder by Canadian paratroopers, its cover-up by senior bureaucrats and officers at National Defence Headquarters and a series of subsequent scandals shook public confidence in the nation’s military institutions. Negative coverage particularly in the first half of the 1990s created an image of military incompetence and unprofessionalism, vividly captured in letters to the editor to major newspapers across the country. In recent years that image was balanced with more positive ones of Canadian Forces personnel protecting the peace in the Former Yugoslavia, Africa, and East Timor. Nevertheless, the spectre of Somalia still lingers in the minds of many both in and out of uniform
