WebEntry.parameters must contain a “hubbards” key which is a dict of all non-zero Hubbard U values used in the calculation. For example, if you ran a Fe2O3 calculation with Materials Project parameters, this would look like entry.parameters[“hubbards”] = {“Fe”: 5.3} If the “hubbards” key is missing, a GGA run is assumed.

WebSection 3.5 - 6 The Hubbard model becomes interesting when both U and t are finite. Consider the finite-U behavior starting from the atomic limit, t = 0.Strictly, at t = 0, the spectrum consists of L copies of the two-level spectrum (Fig. 4.6 above). ! How does this picture change when the electrons start to hop around?
BO21 is a machine learning algorithm that performs global optimization of a black box function by guessing the shape of the function and then iteratively improving it by sequentially sampling points that are promising and/or have high information content.
