The Role of Gradient of the Logarithm of Density in the Quantum Mechanics, Classical Mechanics, the Euler Equation, Equilibrium Statistical Mechanics and Brownian Motion
Francesco R. Ruggeri
It is interesting to note that d/dx [ln(d(x))] where d(x) is the spatial density, plays a central role in the time-independent Schrodinger equation, classical mechanics, the Euler equation, equilibrium statistical mechanics and Brownian motion and in all cases, even the quantum one, is related to force as -d/dx V(x), where V(x) is the potential. In this note, we try to examine the role of d/dx [ln(d(x))], and in particular try to see how quantum mechanics is related to classical and fluid mechanics and how it differs.
