Abstract
In this paper, the Shannon entropy and Fisher information are studied
for the screened Kratzer potential model (SKP). We calculated the
position and momentum entropies for the screened Kratzer potential for
its ground states as well as the first excited state. Our result shows
that the sum of the position and momentum entropies satisfies the lower
bound Berkner, Bialynicki–Birula and Mycieslki (BBM) inequality. Also,
our results showed that decreasing Shannon entropy in the position space
was complemented with an increasing Shannon entropy in the momentum
space. Similarly, we evaluated for Fisher information and show that the
Stam, Cramer-Rao inequalities are satisfied. The squeezing phenomena
were also observed for certain values of the screening parameter α.
