Coulomb analogy for nonhermitian degeneracies near quantum phase transitions
P. Cejnar, S. Heinze, M. Macek
Degeneracies near the real axis in a complex-extended parameter space of a hermitian Hamiltonian are studied. We present a method to measure distributions of such degeneracies on t…

Evolution of spectral properties along the O(6)-U(5) transition in the interacting boson model. II. Classical trajectories
Michal Macek, Pavel Cejnar, Jan Jolie +1
This article continues our previous study of level dynamics in the [O(6)-U(5)]O(5) transition of the interacting boson model [nucl-th/0504016] using the semiclassical theo…

Evolution of spectral properties along the O(6)-U(5) transition in the interacting boson model. I. Level dynamics
Stefan Heinze, Pavel Cejnar, Jan Jolie +1
We investigate the evolution of quantal spectra and the corresponding wave functions along the [O(6)-U(5)]O(5) transition of the interacting boson model. The model is inte…
