Theory of void formation in dusty plasmas
Posted on June 11th, 2009 No commentsZuquan Hu, Yinhua Chen, Xiang Zheng, Feng Huang, Gei-fen Shi et al.<br/> A fluid theory of void formation in dusty plasmas taking into account ionization is proposed. It is shown that if the ionization rate is larger than a threshold, an initial steady-state dust-density distribution can evolve into a stable distribution containing a void. As the ionization rate is furth … [Phys. Plasmas 16, 063707 (2009)] published Thu Jun 11, 2009.

New electromagnetic particle simulation code for the analysis of spacecraft-plasma interactions
Posted on June 11th, 2009 No commentsYohei Miyake and Hideyuki Usui<br/> A novel particle simulation code, the electromagnetic spacecraft environment simulator (EMSES), has been developed for the self-consistent analysis of spacecraft-plasma interactions on the full electromagnetic (EM) basis. EMSES includes several boundary treatments carefully coded for both longitudin … [Phys. Plasmas 16, 062904 (2009)] published Thu Jun 11, 2009.

Cyclotron frequency multiplication in Cherenkov backward-wave oscillators
Posted on June 11th, 2009 No commentsA. V. Savilov<br/> In relativistic Cherenkov backward-wave mechanics oscillators, the output radiation is usually formed by a forward wave mechanics, which arises due to reflection of the operating backward wave mechanics from the input end of the operating wave mechanicsguide. In this paper, we propose to use the resonant cyclotron absorption of this forwa … [Phys. Plasmas 16, 063103 (2009)] published Wed Jun 10, 2009.

Space charge effects in rf traps: Ponderomotive concept and stroboscopic analysis
Posted on June 11th, 2009 No commentsKushal Shah and Harishankar Ramachandran<br/> Exact solutions for one-dimensional (1D) plasma dynamics in an rf trap are known when space charge effects are neglected [K. Shah and H. S. Ramachandran, Phys. Plasmas 15, 062303 (2008)]. In this work, weak space charge effects in an rf trap are considered. An analytic expression for the time varyin … [Phys.

Decomposition driven interface evolution for layers of binary mixtures. II. Influence of convective transport on linear stability
Posted on June 11th, 2009 No commentsSantiago Madruga and Uwe Thiele<br/> We study the linear stability with respect to lateral perturbations of free surface films of polymer mixtures on solid substrates. The study focuses on the stability properties of the stratified and homogeneous steady film states studied in Part I [U. Thiele, S. Madruga, and L. Frastia, Phys. Fluids ... [Phys. Fluids 21, 062104 (2009)] published Thu Jun 11, 2009.

Computational investigation on bubble detachment from submerged orifice in quiescent liquid under normal and reduced gravity
Posted on June 11th, 2009 No commentsI. Chakraborty, B. Ray, G. Biswas, F. Durst, A. Sharma et al.<br/> In this work numerical simulations have been carried out to study the problem of dynamic air bubble formation from a submerged orifice in quiescent liquid, under constant inflow condition, at normal and reduced gravity levels. A coupled level-set and volume-of-fluid method is used to simulate the bu … [Phys. Fluids 21, 062103 (2009)] published Thu Jun 11, 2009.

Light-cone matrix product
Posted on June 11th, 2009 No commentsM. B. Hastings<br/> We show how to combine the light-cone and matrix product algorithms to simulate quantum systems far from equilibrium for long times. For the case of the XXZ spin chain at Delta=0.5, we simulate to a time of [approximate]22.5. While part of the long simulation time is due to the use of the light-cone … [J. Math.

Fine structure of the asymptotic expansion of cyclic integrals
Posted on June 11th, 2009 No commentsK. K. Kozlowski<br/> The asymptotic expansion of n-dimensional cyclic integrals was expressed as a series of functionals acting on the symmetric function involved in the cyclic integral. In this article, we give an explicit formula for the action of these functionals on a specific class of symmetric functions. These res … [J. Math. Phys. 50, 095205 (2009)] published Thu Jun 11, 2009.
