Quantum Phase Transitions in a Finite System
arXiv:nucl-th/0612019
Abstract
A general procedure for studying finite-N effects in quantum phase transitions of finite systems is presented and applied to the critical-point dynamics of nuclei undergoing a shape-phase transition of second-order (continuous), and of first-order with an arbitrary barrier.
