Quantum Information Entropy And Squeezing Of Pt-Symmetric Potential

The information theoretic concepts are crucial to study the quantum mechanical systems. In this paper, the information densities of PT-symmetric potential have been demonstrated and their properties deeply analyzed. The position space and momentum space information entropy is obtained and Bialynicki-Birula-Mycielski inequality is saturated for different parameters of the potential. Some interesting features of information entropy have been discussed. The variation in these entropies is described which gets saturated for specific values of the parameter. These have also been analyzed for the PT-symmetry breaking case. Further, the entropy squeezing phenomenon has been investigated in position space as well as momentum space. Interestingly, PT phase transition conjectures the entropy squeezing in position space and momentum space.
