旋转核中的量子相变

Quantum phase transitions in rotating nuclei

R. G. Nazmitdinov, J. Kvasil

摘要:

我们推广了经典的朗道旋转核理论,并证明了162 Yb中由于两准粒子排列而产生的回弯与二级相变是一致的.我们发现,156 Dy的回弯,所造成的不稳定性的$γ$ -振动的旋转框架,对应于一级相变。

英文摘要:

We extend the classical Landau theory for rotating nuclei and show that the backbending in 162Yb, that comes about as a result of the two-quasiparticle alignment, is identified with the second order phase transition. We found that the backbending in 156Dy, caused by the instability of $γ$-vibrations in the rotating frame, corresponds to the first order phase transition.
