TTN.jl -- A tree tensor network library for calculating groundstates and solving time evolution

This is a package for working with tree tensor networks based on ITensors.jl library. It provides basic tools for defining quantum states in arbitrary dimensions using a hierarchic structure without loops, called a tree. This includes the calculation of local observables, correlation functions, and entanglement entropy of bipartitions, as well as providing a toolbox for finding the ground state of local Hamiltonians and calculating the time evolution of quantum states with respect to local Hamiltonians.
