Abstract

Model hamiltonians are a useful tool to approach the many-body problem in materials. They often provide valuable physical insight and enable larger length-scale studies. However, since model parameters are invariably unknown, this approach often lacks predictive power, an issue that turns more significant in materials with strong electronic correlations. Being able to controllably...
