چکیده
We present theoretical and numerical evidence to show that self-defocusing nonlinear optical propagation can be used to compute Euler fluid dynamics and possibly Navier-Stokes fluid dynamics. In particular, the formation of twin vortices and the Kármán vortex street behind an obstacle, two well-known viscous fluid phenomena, is numerically demonstrated using the nonlinear Schrödinger equation. c © 2006 Optical Society of America OCIS codes: (200.0200) Optical computing; (190.5530) Pulse propagation and solitons

Frequency Quantized Nondiffracting X Waves in a Confined Space
ar X iv :p hy si cs /0 60 70 59 v 1 7 Ju l 2 00 6 Abstract This paper presents theoretical results indicating that newly discovered nondiffracting beams we call X waves, can propagate in a confined space (wave guide) with specific quantized temporal frequencies. These results could have applications in nondispersive transmission of acoustic, electromagnetic (microwaves) and optical energy throu...

This paper presents a procedure to perform fully autonomous on orbit alignment of the interferometer on board the LISA technology package (LTP). LTP comprises two freefloating test masses as inertial sensors that additionally serve as end-mirrors of a set of interferometers. From the output signals of the interferometers, a subset has been selected to obtain alignment information of the test ma...

We study a general set of models of social network evolution and dynamics. The models consist of both a dynamics on the network and evolution of the network. Links are formed preferentially between ’similar’ nodes, where the similarity is defined by the particular process taking place on the network. The interplay between the two processes produces phase transitions and hysteresis, as seen usin...

We discuss a parity nonconserving asymmetry in the cross section of KLL dielectronic recombination of polarized electrons on the hydrogen-like ions with Z ∼ 60. This effect is strongly enhanced because of the near-degeneracy of doubly-excited 2l2l states of opposite parity in He-like ions. For ions with Z ∼ 30 the asymmetry is of the order of 10. For Z ≈ 48 a level crossing takes place, leading...
