摘要
Jordan Wigner变换和玻色化技术的基础上对sineGordon方程使用标量场方法和量子自恰近似 ,我们研究了在低温下时二聚化对激发谱中的能隙和比热的影响 .在临界温度Tc 点 。
By using the scalar field mechanical approach and quantum self consistent approximation to the sine Gordon equation based on the Jordan Wigner transformation and bosonization techniques,we studied the effect of the dimerization on the excitation energy gap and specific heat at low temperatures.Successive phase transition happened at critical temperature T c.
