Abstract
There is a research field called a fluctuating system. In systems such as Brownian motion, the particles of interest exchange kinetic energy from white noise and perform a random walk. The Langevin equation handles these events and takes up fine particle friction and microwave irradiation to confirm the operation of the system. In this paper, we incorporate microwave irradiation into the Maxwell-Boltzmann distribution and confirm that its non-thermal energy exhibits the so-called "microwave effect". As a sample case using correlated noise, two-dimensional Ising model is proposed as a specific example of Monte Carlo simulation. Results will vary depending on the strength of the noise correlation. In this way, the noise-to-noise correlation has a strong effect on physical quantities.
