  This work describes coherent states for a physical system governed by a
Hamiltonian operator, in two dimensional space, of spinless charged particles
subject to a perpendicular magnetic field B, coupled with a harmonic potential.
The underlying su(1, 1) Lie algebra and Barut-Girardello coherent states are
constructed and discussed. Then, the Berezin - Klauder - Toeplitz quantization,
also known as coherent state (or anti-Wick) quantization, is discussed. The
thermodynamics of such a quantum gas system is elaborated and analyzed.
