摘要
对六角格子的实空间重整化群计算[1]作了进一步的研究,把六角格子的配位数作为一个变量加以推广,引进配位数因子和近邻相互作用因子.得到包含这两个因子的重整化群变换,以及随这两个因子的取值不同而取不同值的相变点,结论是相变点随这两个因子的升高而降低.
The calculation of real space renormalization group on hexagonal lattice is studied further.The coordination number of hexagonal lattice is generalized as a variable,and coordination number factor Z and nearest-neighboring interaction factor a are introduced.We obtain the renormalization group transformations including the two factors,and get phase transition points when the two factors take different values.The results are obtained that the value of phase transition point decrease with rise of the two factors.
