Coherent states and dissipation for the motion of a charged particle in a constant magnetic field

摘要: We deal with the motion of a charged particle in constant magnetic field when immersed medium that exerts some type friction. analyse problem classically and also quantum mechanically. In latter case we use coherent state solutions that, for large energies, compared one associated cyclotron frequency, reduce to classical limit. To study dynamical behaviour time-dependent wave packets can be constructed by superposition states.
