Lowest-known Energy Configuration of Coulomb Charges in a Disk: Breaking the Barrier
Georgiy K. Lavrov, Eduard G. Nikonov
We report the first calculation of the lowest-known energy configuration for classical point charges confined to a disk and interacting via the Coulomb potential…
Global Minima of the Thomson Problem in a Disk: A Molecular Dynamics Approach with Fixed Border Charges
Georgiy K. Lavrov, Eduard G. Nikonov
We report improved global-minimum configurations for the classical Thomson problem of , , , and repulsive Coulomb charges confined to a disk. By combining the qu…
Shannon Entropy as an Order Parameter for the Two-Dimensional Confined Coulomb Systems: Exact Balance Law, Topological Charge Sum Rule, and Boundary Saturation
Goergiy K. Lavrov, Georgiy K. Lavrov, Eduard G. Nikonov
We establish a complete information-theoretic framework for the minimum-energy configurations of the two-dimensional Thomson problem on a hard-wall disk, based on the Shannon entro…
Investigating the response of single pad and hybrid pixel detectors (Si, GaAs, CdTe, CZT) for 226Ra and 137Cs
G. Chelkov, S. Abou El-Azm, U. Kruchonak +5
The development of hybrid pixel detectors for particle detection with high spatial resolution in high energy physics experiments has spun off a number of developments with applicat…
