The Effect of Coordination Number on Phase Transition Point from the Study of Renormalization Group Calculation for Hexagonal Lattice
Wenchen He · Journal of Hebei University of Technology · 2004
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.
