In collaboration with Dr. Tomono, I have submitted a paper titled &#34;Period and intrinsic noises of permanent spin vortex system centered by small polaron&#34; to the archive. This paper shows the results of simulating the time evolution in a spin vortex system by applying the time evolution operator to the quantum state using the Suzuki-Trotter expansion. As a result, it was found that the spin vortex system created by the small polaron has a period and evolves in time. The results show that the spin vortex system created by the small polaron evolves in time with a period, which confirms that the structural noise oscillates the energy levels of the system when there is a non-zero distribution of the spin magnetic moment. In systems such as spin vortex-induced loop currents, there is no distribution of the spin magnetic moment, so a perfect system is unaffected. However, if there is a spin-magnetic moment distribution due to excess or deficiency of holes, etc., it brings level noise to the system, which increases in proportion to the magnetic field. This could be used in the future to detect structural defects and hole positions in spin vortex-induced loop current systems. https://arxiv.org/abs/2112.06561v1
