The Minimal Length and the Shannon Entropic Uncertainty Relation

الملخص EN

In the framework of the generalized uncertainty principle, the position and momentum operators obey the modified commutation relation X,P=iħ1+βP2, where β is the deformation parameter.

Since the validity of the uncertainty relation for the Shannon entropies proposed by Beckner, Bialynicki-Birula, and Mycielski (BBM) depends on both the algebra and the used representation, we show that using the formally self-adjoint representation, that is, X=x and P=tanβp/β, where [x,p]=iħ, the BBM inequality is still valid in the form Sx+Sp≥1+lnπ as well as in ordinary quantum mechanics.

We explicitly indicate this result for the harmonic oscillator in the presence of the minimal length.
