Abstract

Phase transition and current of planar clusters with loops of Josephson $\pi$ junction is of great importance for application in the adiabatic quantum computation devices (AQC). Each $\pi$-ring possesses an orbital moment with a current. The orientation of these orbital moments is altered by self-interactions and controlled with a bias current. In the current research, we construct the phase diagram of semi-hydrogenated SiB (H-SiB) semiconductor using a two-dimensional (2D) Ising model with considering nearest-neighbor and diagonal interactions of spin planes on the on the hexagonal lattice. Our findings reveal that by decreasing temperature, two phase transitions of order and disorder occur and at low temperatures a glassy state appears, where this model maps to spin qubit. We theoretically study the magnetostriction effect by considering of laser electromagnetic field coupled to the spin planes of electric polarization of magnetic insulator for both unstrained and strained H-SiB monolayers. The dynamic of laser-spin coupling and spin current shows nonlinear optical effects and high-harmonic generation (HHG) under both terahertz (THz) and gigahertz (GHz) electromagnetic waves. The findings of this research open an avenue for experimentalists how to detect HHG in the topological insulators, Dirac systems, Mott insulators, and superconducting memories.
