英文摘要	We study the nematic isotropic phase transition by applying the functional renormalization group to the Landaude Gennes model. We derive the flow equations for the effective potential as well as the "couplings" constants and the anomalous dimension. We then solve the coupled flow equations on a grid using the Newton-Raphson method. A first-order phase transition is observed. We also investigate the nematic isotropic puzzle (the NI puzzle) in this paper. We obtain the NI transition temperature difference T-c - T* = 5.85 K.
