FRGn

---

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

Installation

Clone this repository

git clone https://github.com/biplab37/FRGn.git

Add the file path to the PATH of julia.

julia> push!(LOAD_PATH,location/to/the/file)

One should add this line to the file "~/.julia/config/startup.jl" to avoid running the command in each julia session.

After that you can add this package

julia> ]add FRGn

To import or use the functions in the package

julia> using FRGn

Following functions are available in this package.

• get_velocity
• 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).
