Renyi entropy of the infinite well potential in momentum space and
Dirichlet-like trigonometric functionals    [PDF]

Alexander I. Aptekarev, Jesus S. Dehesa, Pablo Sánchez-Moreno, D. N. Tulyakov

The momentum entropic moments and R\'enyi entropies of a one-dimensional particle in an infinite well potential are found by means of explicit calculations of some Dirichlet-like trigonometric integrals. The associated spreading lengths and quantum uncertainty-like sums are also provided.
