Long-time tails in quantum Brownian motion
- The authors address the problem of quantum Brownian motion at low temperatures and with arbitrarily strong damping. For a harmonically bound particle the zero-temperature correlation functions are shown to display long-time tails. At finite temperatures an power-law decay at intermediate times is followed by an exponential decay with time constant ħ/2πkBT. The case of free Brownian motion is treated, and some general conclusions for nonlinear systems are drawn.
