Nuclear chiral rotation induced by superfluidity

The microscopic understanding on the influence of pairing correlations or superfluidity nuclear chiral rotation has been a longstanding and challenging problem. Based three-dimensional cranking covariant density functional theory, shell-model-like approach with exact particle number conservation is implemented to take into account applied for doublet bands in Nd135. data available are well reproduced. It found that can reduce critical frequency make easier. mechanism particle/hole alignments along short/long axis reduced by correlations, resulting enhanced preference collective intermediate axis, inducing early appearance rotation.
