| Abstract: | We study the quantum Brownian motion of a charged particle in the presence of a magnetic field. From the explicit solution
of a quantum Langevin equation we calculate quantities such as the velocity correlation function and the mean-squared displacement.
Our calculated expressions contain as special cases the motion of aclassical particle in a magnetic field and that of afree (but quantum) particle, in a dissipative environment. |
