Dissipative quantum dynamics of a charged particle in a magnetic field
Yatin Marathe · Physical Review A · 1989
We calculate the position autocorrelation and magnetic moment of a charged particle at finite temperatures moving in two dimensions in the presence of a magnetic field and a dissipative environment. We show that the time-dependent position-autocorrelation function does not change qualitatively from the free-particle behavior. This implies that orbital magnetic moment of a charged particle is zero at all temperatures.
