A Charged Particle in a Magnetic Field: A Review of Two Formalisms of Coherent States and the Husimi Function
Herrera, D.; Valencia, A. M.; Pennini, F.; Curilef, S.
European Journal of Physics, v29 n3 p439-449 May 2008
In this work, we review two formalisms of coherent states for the case of a particle in a magnetic field. We focus our revision on both pioneering (Feldman and Kahn 1970 "Phys. Rev." B 1 4584) and recent (Kowalski and Rembielinski 2005 "J. Phys. A: Math. Gen." 38 8247) formulations of coherent states for this problem. We introduce a general application, the Husimi function, which takes into account collective and environmental effects, and which can be derived in a variety of ways. However, we calculate this function as the expected value of the density operator in a basis of coherent states. (Contains 2 figures.)
