Computer simulation of shape effects in electrostatic and magnetostatic interactions
It is well known that an uncharged conductor attracts charged bodies due to electrostatic induction. However, complex-shaped conductors can repel charged bodies. In this case attraction is replaced by repulsion at a certain distance between the bodies. This phenomenon is known as “repulsion effect” [1]....
We consider the phase dynamics in long superconductor-ferromagnet-superconductor $\varphi_0$ Josephson junction described by the modified sine-Gordon equation. In such a junction the Josephson phase and magnetic moment are coupled due to spin-orbit coupling. This allows the manipulation of magnetic properties by Josephson current and vice versa. We investigate the effect of the spin-orbit...
The aim of this work was to study the variation of the thermal conductivity of composite materials usually used as glues in experimental setups when exposed to different dose levels of ionizing radiation. The samples under study were epoxy resins filled with diamond powder irradiated with high-energy protons and neutrons. The thermal conductivity of each samples was measured before and after...
Within the framework of the joint project of LIT and BLTP JINR, a toolkit is being developed for investigation of systems containing Josephson junctions based on Jupyter using Python libraries. It should be noted that a number of tasks require numerous resource-intensive calculations, which leads to the need for significant acceleration of computational schemes implemented in Python and the...
A good number of applications in physics (and not only) rely on
random number generation for Monte Carlo purposed (or key distribution,
and other tasks).
Most at hand random servers are hash function based, with carefully
studied and tuned algorithms. Depending on complexity and quality of
the samples produced, they can be very good quality like RANLUX (with
10^171 period), or...
Fractals are objects that are fragmented to such an extent that measuring them with the measures we are accustomed to (length, area, volume) gives different results depending on the choice of the measuring segment (scale). The concept of "fractal" was introduced by Benoit Mandelbrot [1], who also laid the foundation for a new "fractal" geometry. Using modeling experiments on small-angle light...
The achievement of high accuracy in theoretical modeling of the electronic structure of materials containing f-elements, in particular lanthanides and actinides, requires simultaneous consideration of relativistic and correlation effects. The most promising method that satisfies this requirement is the relativistic coupled cluster method (RCC), which leads to extremely resource-intensive...
