Web26 aug. 2024 · Since the original Marcus–Hush theory is semiclassical where nuclear motion is classic, a number of efforts have then been devoted to take the quantum nature of nuclei into consideration, for instance, by Bixon, Jortner and co-workers. 32–37 32.

For real materials, each lattice site might correspond with an ionic core, and the particles would be the valence electrons of these … Meer weergeven The Hubbard model is an approximate model used to describe the transition between conducting and insulating systems. It is particularly useful in solid-state physics. The model is named for John Hubbard. The … Meer weergeven The model was originally proposed in 1963 to describe electrons in solids. Hubbard, Martin Gutzwiller and Junjiro Kanamori each independently proposed it. Since then, it has been applied to the study of Meer weergeven Although Hubbard is useful in describing systems such as a 1D chain of hydrogen atoms, it is important to note that more complex … Meer weergeven Stacks of heterogeneous 2-dimensional transition metal dichalcogenides (TMD) have been used to simulate geometries in more than … Meer weergeven The hydrogen atom has one electron, in the so-called s orbital, which can either be spin up ($${\displaystyle \uparrow }$$) or spin down ($${\displaystyle \downarrow }$$). This orbital can be occupied by at most two electrons, one with spin up and one down (see Meer weergeven The fact that the Hubbard model has not been solved analytically in arbitrary dimensions has led to intense research into numerical methods for these strongly correlated … Meer weergeven • Anderson impurity model • Bloch's theorem • Electronic band structure • Solid-state physics Meer weergeven increased blood pressure and headache
