To study the mechanism of the PCL formation it is necessary to analyze the melt structure in order to see the distribution and concentration of dynamic clusters in it. For this purpose we used a system of 4 million atoms. To make results more…

Exceptional point and hysteresis trajectories in cold Rydberg atomic gases
Physical model
Our model is based on a three-level Rydberg atom system, as depicted in Fig. 1a. There are three atomic state manifolds of ground state \(\vert g \rangle\), metastable state \(\left\vert e\right\rangle\), and Rydberg state

Quantum annealing applications, challenges and limitations for optimisation problems compared to classical solvers
Simulated Annealing (SA) is used for approximating the global optimal solution, often used when an approximate global solution is preferred over an exact local minimum38. The fundamental principle of SA involves a two-phase process: initially…

Theory of potential impurity scattering in pressurized superconducting La3Ni2O7
Disordered bilayer model
We consider a bilayer Hamiltonian with point-like non-magnetic impurities \({{{\mathcal{H}}}}={{{{\mathcal{H}}}}}_{0}+{{{{\mathcal{H}}}}}_{{{{\rm{int}}}}}+{{{{\mathcal{H}}}}}_{{{{\rm{dis}}}}}\), where the interaction term…

Generation of field-reversed configurations via neutral beam injection
Machine configurations
Extensive details of the original configuration of Norman are given elsewhere13,14.
Both the original and present forms are illustrated in Fig. 1. In the Norm configuration, plasmas primarily reside in the CV bounded at each…
