MONTE CARLO STUDY OF SU(2) GROUP SPACE DECIMATION EFFECTIVE ACTION

  • We perform Monte Carlo simulation for the SU(2)-Y(120) group space decimation approximate effective action in 44 periodic lattice, find that the effective action system does not have freezing point at β≤9, but the internal energy curve of the system is different from that of SU(2) group with Wilson action. This indicates that although group space decimation method in principle can make discrete subgroup substitute for continuous group available in Monte Carlo simulation, it is not an effective method as to save MC computer time.

MONTE CARLO STUDY OF SU(2) GROUP SPACE DECIMATION EFFECTIVE ACTION

    Corresponding author: LI Wen-Zhu,

Abstract: We perform Monte Carlo simulation for the SU(2)-Y(120) group space decimation approximate effective action in 44 periodic lattice, find that the effective action system does not have freezing point at β≤9, but the internal energy curve of the system is different from that of SU(2) group with Wilson action. This indicates that although group space decimation method in principle can make discrete subgroup substitute for continuous group available in Monte Carlo simulation, it is not an effective method as to save MC computer time.
