Abstract By invoking the concept of displaced number state in quantum optics, the complete eigen-states in one-dimensional mesoscopic rings with electron-phonon coupling are abtained and the eignevalues followed. It is shown that the eigenvalues and persistent current depend on both coupling strength and phonon number.
