MECHANICAL OSCILLATORS ANALOGS AND ELECTROMAGNETICALLYINDUCED-TRANSPARENCY (EIT) PHENOMENA IN A FOUR-LEVEL INVERTED -Y ATOMIC SYSTEM

Abstract

In this work, we develop research on a classical analogy of electromagnetically induced transparency (EIT) for a four-level Y-type atomic medium using a mechanical oscillator system. According to that, the mechanical oscillator system has been proposed to illustrate for the exited scheme of four-level Y-type atomic system. It is shown that both of the absorption and dispersion spectra of the mechanical powers are very similar to that of the four-level Y-type atomic system. This classical analogy provides simple and intuitive physical description of complex quantum interference processes that occur in the atomic system and can be used to illustrate experimental observations of the EIT and related effects in quantum systems.
