Effective critical points in finite quantum phase transitional systems

Williams, Elizabeth; Casperson, R.J.; Werner, V.


Properties of quantum phase transitional systems in atomic nuclei are explored within the context of the interacting boson model 1 for both first and second order systems. A traditionally experimental approach is used to search for the effective finite-size critical point as a function of system size and angular momentum by studying derivatives of observables across the phase transition region. The effects of angular momentum on quantum phase transitions are investigated, and properties of...[Show more]
