Study of Shannon Entropy in the Context of Quantum Mechanics: An Application to Free and Confined Harmonic Oscillator

Abstract: INTRODUÇÃO No prefácio de seu livro Introduction to Nonextensive StatisticalMechanics, Constantino Tsallis relata um diálogo bem interessante entre Claude Shannon e John Von Neumann. Conta-se que Shannon, indeciso sobre como chamar a função por ele derivada, pensou inicialmente em chamá-la de informação, mas este nome já era muito usado. Depois de muito pensar, resolveu chamá-la de função incerteza. Entretanto, nesta conversa foi aconselhado por John Von Neumann:1 "Você deve chamá-la de entropia, por duas razõ… Show more

“…In the region where the confinement effect is rigorous the quantity S r may assume negative values, as shown in Table 2 and in Refs. [18,22,33]. This result has a simple explanation in the quantum context [19]: when r c is reasonably small, the probability density becomes large and a n 0 ρ( r) > 1.…”
