What Does EHM Stand For?

EHM stands for Extended Hubbard Model Hamiltonian

The Extended Hubbard Model Hamiltonian (EHM) is a theoretical framework used in condensed matter physics to describe the behavior of interacting electrons in a lattice. It extends the traditional Hubbard model by incorporating additional interactions, such as next-nearest neighbor hopping and longer-range Coulomb interactions, allowing for a more comprehensive analysis of phenomena such as superconductivity, magnetism, and charge density waves in various materials. The EHM serves as an essential tool for understanding complex electronic systems and their emergent properties.
