| Abstract: | The Statistical properties of Brownian bound oscillator under the Markovian limit are studied. Time-dependent solutions are obtained for the position of the oscillator under adia-batic approximation. Statistical quantities for the position and moments of the oscillator, i. e. , the first-order moments, the second-order moments, the cross-correlation functions and the self-correlation functions as well as the relaxation time have been calculated. The mean first-passage time of the Brownian bound oscillator is obtained. |
