This package contain the subroutines that are frequently shared between different codes to solve exact FRG equations.

Installation

The package can be added from the julia REPL

julia> ]add https://github.com/biplab37/FRGn

Or through Pkg,

• get_dielectric
• rg_procedure
• plot_velocity
• plot_dielctric

To know more about each of the functions use help. Typing '?' in the julia REPL will get you to help and then type the function name that you want help with.

julia> ?

help?> get_velocity

search: get_velocity

   get_velocity(velocity::Array{Float64,2}, k1::Float64, k2::Float64, m::Int64, n::Int64, i::Int64)

Returns the velocities at momenta k1 and k2 at the previous cutoff (indexed m-i+2).
