  • Renormalization group domains of the scalar Hamiltonian 
    Bagnuls, C.; Bervillier, C. (Condensed Matter Physics, 2000)
    Using the local potential approximation of the exact renormalization group (RG) equation, we show various domains of values of the parameters of the O(1) -symmetric scalar Hamiltonian. In three dimensions, in addition ...
  • The Wilson exact renormalization group equation and the anomalous dimension parameter 
    Bervillier, C. (Condensed Matter Physics, 2013)
    The non-linear way the anomalous dimension parameter has been introduced in the historic first version of the exact renormalization group equation is compared to current practice. A simple expression for the exactly marginal ...
