Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: multi-orbital Hubbard model | Statement: [Hubbard model, hasVariant, multi-orbital Hubbard model]

Target entity: multi-orbital Hubbard model
Context triple: [Hubbard model, hasVariant, multi-orbital Hubbard model]

• A. Hubbard model
  The Hubbard model is a fundamental theoretical model in condensed matter physics that describes interacting electrons on a lattice and is widely used to study phenomena such as magnetism, metal–insulator transitions, and high-temperature superconductivity.
• B. Dynamical Mean-Field Theory
  Dynamical Mean-Field Theory is a non-perturbative theoretical approach in condensed matter physics that captures local electronic correlations by mapping lattice models onto self-consistent quantum impurity problems, enabling the study of phenomena such as the Mott metal–insulator transition.
• C. t-J model
  The t-J model is a theoretical framework in condensed matter physics used to describe strongly correlated electrons on a lattice, particularly in the study of high-temperature superconductivity.
• D. Simons Collaboration on the Many Electron Problem
  The Simons Collaboration on the Many Electron Problem is a research initiative that brings together mathematicians and physicists to develop new theoretical and computational approaches for understanding complex many-electron systems in quantum mechanics and condensed matter physics.
• E. Gutzwiller approximation
  The Gutzwiller approximation is a variational method in condensed matter physics used to study strongly correlated electron systems, particularly metal–insulator (Mott) transitions in lattice models like the Hubbard model.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: multi-orbital Hubbard model
Target entity description: The multi-orbital Hubbard model is an extension of the standard Hubbard model that includes multiple electronic orbitals per lattice site to study more realistic correlated electron systems and orbital-dependent phenomena.
