Renormalization Group Reduced Density Matrix

RGRDMT.jl is a julia library for finding the lower bound to the ground state energy of a translationally invariant Hamiltonian. The library is based on the paper ^[1].

This library uses Convex Optimization^[2] to find the lower bound to the ground state energy by optimizing a reduced density matrix. Concepts of renormalization group^[3] were employed to reduce the dimension of the problem.

Quick Start

Currently, we have included tested optimizers for Convex Optimization and the package is plug-and-play. You will only need to install the package by running the following code.

using Pkg
Pkg.add("RGRDMT")

For detailed usage, please refer to the test case in test/example.jl
