TEDOPA

TEDOPA is a package for computing the chain mapping of spectral densities of both bosonic and fermionic environments. Starting from the spectral density function, the temperature and the chemical potential (if applicable), it computes the chain coefficients of the TEDOPA-transformed environment, applying a thermalisation procedure such as T-TEDOPA or the thermofield transformation.

Installation

From a registry

This package is registered in the TensorNetworkSimulations registry. If you haven't already done so, add it to your Julia installation by running

using Pkg
pkg"registry add https://github.com/phaerrax/TensorNetworkSimulations.git"

(this must be done just once per Julia installation). The package can then be installed as a normal one:

using Pkg
pkg"add TEDOPA"

From GitHub

Alternatively, straight installation from GitHub is also possible:

using Pkg
pkg"add https://github.com/phaerrax/TEDOPA.jl"
