1101.1242 (J. Bernal et al.)

On the classical limit of quantum mechanics    [PDF]

J. Bernal, Alberto Martín-Ruiz, J. C. García-Melgarejo
In this paper, we suggest a simple mathematical procedure to connect the classical and quantum probability densities for both position and momentum via Bohr's correspondence principle. Using a Fourier expansion of the classical and quantum distribution, respectively, we postulate that the Fourier coefficients have a similar behavior for large quantum number $n$. We discuss the classical limit for two simple quantum systems. The most important result is the emergence of classical distribution, keeping Planck's constant non-zero. We interpret the correction terms ($\hbar$-dependent) as a residual effect of quantum behavior surviving at the classical level.
