Regularity and chaos at critical points of first-order quantum phase transitions

M. Macek, A. Leviatan
2011 Physical Review C  
We study the interplay between regular and chaotic dynamics at the critical point of a generic first-order quantum phase transition in an interacting boson model of nuclei.  ...  A quantum analysis of the spectra separates the regular states from the irregular ones, assigns them to particular phases, and discloses persisting regular rotational bands in the deformed region.  ...  Such global measures of quantum chaos are, however, insufficient to reflect the rich dynamics of an inhomogeneous phase space structure, as in Fig. 1 , with well separated regular and chaotic regions.  ...
