Query: Entropic comparison of Landau-Zener and Demkov interactions in the phase
  space of a quadrupole billiard   We investigate two types of avoided crossings in a chaotic billiard within
the framework of information theory. The Shannon entropy in the phase space for
the Landau-Zener interaction increases as the center of the avoided crossing is
approached. Meanwhile, that for the Demkov interaction decreases as the center
of avoided crossing is passed by with an increase in the deformation parameter.
This feature can provide a new indicator for scar formation. In addition, it is
found that the Fisher information of the Landau-Zener interaction is
significantly larger than that of the Demkov interaction.
