摘要:

本文利用突变理论的形成,研究了由仿射SU(1,1)代数定义的U(5)-SO(6)跃迁哈密顿量的相变点.本文考虑了Ru和Pd的偶偶同位素的能面,确定了E(5)临界点的最佳候选同位素。此外,基态量子相变的临界指数与热力学相变的临界指数的朗道值之间的类比进行了描述。

英文摘要:

In the present paper, by employing the formation of the Catastrophe Theory, the phase transition points for U(5)-SO(6) transitional Hamiltonian, which is defined according to the affineSU(1,1)algebra are investigated. The energy surfaces of the even-even isotopes of Ru and Pd nuclei are considered and special isotopes which are the best candidates for theE(5) critical point are identified. Also, the analogy between the critical exponents of ground-state quantum phase transition and Landau values for the critical exponents of thermodynamic phase transition are described.
