We apply the projected Gross-Pitaevskii equation (PGPE) formalism to the experimental problem of the shift in critical temperature Tc of a harmonically confined Bose gas as reported in Gerbier et al., Phys. Rev. Lett. 92, 030405 (2004). The PGPE method includes critical fluctuations and we find the results differ from various mean-field theories, and are in best agreement with experimental data...

One typically observes differing trends in the distribution of gross incomes across countries. Where do these inequalities originate from? We consider a simple model where individuals have identical preferences but different abilities, and we investigate the impact on the distribution of gross income of changes in the way abilities are distributed among the individuals. Journal of Economic Lite...

Strongly-interacting bosons in two-dimensional harmonic traps are described through breaking of rotational symmetry at the Hartree-Fock level and subsequent symmetry restoration via projection techniques, thus incorporating correlations beyond the Gross-Pitaevskii (GP) solution. The bosons localize and form polygonal-ringlike crystalline patterns, both for a repulsive contact potential and a Co...

Since the Pennsylvania oil rush of 1859, petroleum has quickly become dominant fuel industrial society. The “Peak Oil” debate focused on whether or not there was an impending production crunch cheap oil, and whilst have been no shortages across globe, a shift from conventional to unconventional liquids occurred. One aspect this fully explored in previous discussions–although some importance low...

A wideband on-body antenna for a wireless body area network for an Industrial, Scientific, and Medical band is proposed. A wideband characteristic is achieved by combining two zeroth-order resonance (ZOR) modes at adjacent frequencies by controlling the value of the shunt capacitance. The size of the proposed antenna is 0.072λ0 × 0.33λ0, and the measured 10-dB return loss bandwidth is 340 MHz (...

In this paper we study a cost allocation problem that is inherent to most energy networks: the allocation of losses. In particular, we study how to allocate gas losses between haulers in gas transmission networks. We discuss four allocation rules, two of them have already been in place in real networks and two others that are defined for the first time in this paper. We then present a comparati...
