As a continuation of our previous work, we derive the optimal flux phase which minimizes the ground state energy in the one-dimensional many particle systems, when the number of particles is odd in the absence of on-site interaction and external potential. Moreover, we study the relationship between the flux on the ring and the spin of the ground state through which we derive some information o...

One of the most often studied features of mesoscopic systems are the persistent currents in rings threaded by a magnetic flux – let us mention, e.g., [CGR, CWB] and scores of other theoretical and experimental papers where they were discussed. For a charged particle (an electron) confined to a loop Γ the effect is manifested by the dependence of the corresponding eigenvalues λn on the flux φ th...

The conversion of the Crab pulsar wind from one dominated by Poynting flux close to the star to one dominated by particle-born energy at the termination shock is considered. The idea put forward by Coroniti (1990) and criticised by Lyubarsky & Kirk (2001) that recon-nection in a striped wind is responsible, is generalised to include faster prescriptions for the a priori unknown dissipation rate...

in order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. silver-oil nanofluid prepared by electrical explosion of wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. the average size...

The atmospheric neutrino flux calculated with FLUKA was originally limited to 100÷200 GeV for statistical reasons. In order to make it available for the analysis of high energy events, like upward through-going muons detected by ν telescopes, we have extended the calculation so to provide a reliable neutrino yield per primary nucleon up to about 10 GeV/nucleon, as far as the interaction model i...

The Pfirsch-Schlüter transport of impurities is calculated for stellarator geometry. Contrary to the tokamak case, where the only contribution to the particle flux arises from friction between different species, in a stellarator there is another source of impurity transport due to pressure anisotropy. However, the pressure anisotropy term is usually smaller than the friction term, so that the i...

Abstract We examine the effects of two-body interactions in a nuclear star cluster surrounding supermassive black hole. evaluate energy flux, analogously to particle flux calculation Bahcall and Wolf. show that there are two types power-law steady-state solutions: one with zero constant other flux. therefore prove solution, which corresponds case an accreting hole, can be obtained by requiring ...

This paper presents a novel, unified approach to the theory of turbulent transport of parallel momentum by collisionless drift waves. The physics of resonant and nonresonant off-diagonal contributions to the momentum flux is emphasized, and collisionless momentum exchange between waves and particles is accounted for. Two related momentum conservation theorems are derived. These relate the reson...
