چکیده
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 to the PNC asymmetry of −1.3 × 10, which is 10 times greater than the basic strength of the weak interaction in atoms.

We introduce and study a general model of social network formation and evolution based on the concept of preferential link formation between similar nodes and increased similarity between connected nodes. The model is studied numerically and analytically for three definitions of similarity. In common with real-world social networks, we find coexistence of high and low connectivity phases and hi...

We review the history of the parallel tempering simulation method. From its origins in data analysis, the parallel tempering method has become a standard workhorse of physiochemical simulations. We discuss the theory behind the method and its various generalizations. We mention a selected set of the many applications that have become possible with the introduction of parallel tempering and we s...

The generation of large-scale zonal flows by small-scale electrostatic drift waves in electron temperature gradient(ETG) driven turbulence model is considered. The generation mechanism is based on the modulational instability of a finite amplitude monochromatic drift wave. The threshold and growth rate of the instability as well as the optimal spatial scale of zonal flow are obtained.

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. ...
