Diffraction limit of the sub-Planck structures
Raman Sharma, Prasanta K. Panigrahi
The orthogonality of cat and displaced cat states, underlying Heisenberg limited measurement in quantum metrology, is studied in the limit of large number of states. The asymptotic…

Super revivals and sub-Planck scale structures of a slightly relativistic particle in a box
Suranjana Ghosh, Irene Marzoli
The time evolution of a particle, caught in an infinitely deep square well, displays unexpected features, when one includes tiny relativistic effects. Indeed, even the smallest cor…
