Director Orientation

A two-dimensional model of Fredericks effect was used for the investigation of the static electric field influence on nematic liquid crystal director orientation in the side-electrode cell. The solutions of the equations describing the model were obtained by finite-difference methods. Fredericks transition threshold for the central part of the cell, as well as dependencies of the distribution of the director orientation patterns on the electric field and location, were obtained. The numerical results are found to agree qualitatively with the experiment. Further investigations are needed to elucidate completely the Fredericks effect.

Laser Solid Interactions

The emission of high-energy protons in laser–solid interactions and the theories that have been used to explain it are briefly reviewed. To these theories we add a further possibility: the acceleration of protons inside the target by the electric field generated by fast electrons. This is considered using a simple one-dimensional model. It is found that for relativistic laser intensities and sufficiently long pulse durations, the proton energy gain is typically several times the fast electron temperature. The results are very similar to those obtained for proton acceleration by electron expansion into vacuum.

The longitudinal dynamics of protons in hydrogen-bonded chains is studied in the framework of a simple one-component one-dimensional model with a two-parameter doubly periodic symmetric on-site potential proposed by Zolotaryuk and Pnevmatikos (1990) under an external electric field and damping. The behavior of the ionic and bonding defects has been proved analytically and numerically to exhibit particle-like properties. Mobilities of the dc and ac driven defects have also been calculated with different methods. Small-amplitude oscillating solutions of breather and envelope solitons have been studied analytically and numerically.
