The new edition of an introductory text that teaches students the art of computational problem of the tools and techniques of data science for using computation to model and interpret data. Java Data Analysis E-bok by John R. Hubbard
The Hubbard model is a "highly oversimplified model" for electrons in a solid which interact with each other through extremely short ranged repulsive (Coulomb) interaction.

In these elements, the radial wave function of the 3d-electrons has a very small spatial extent. Therefore, when the 3dshell is occupied by several electrons, these are forced to be close to one
1 Introduction The Hubbard Hamiltonian (HH) offers one of the most simple ways to get insight into how the interactions between electrons give rise to insulating, magnetic, and even novel superconduct-ing effects in a solid. It was written down [1–4] in the early 1960’s and initially applied to

Elementary Introduction to the Hubbard Model I. INTRODUCTION The Hubbard model offers one of the most simple ways to get insight into how the interac-tions between electrons can give rise to insulating, magnetic, and even novel superconducting effects in a solid.
The Hubbard model describes a one dimensional I. INTRODUCTION For nearly flfty years, the Hubbard model1 has been used to describe many-body efiects in solids, capturing the dominant competition between the delocalizing ef-fects of the kinetic energy (with strength described by a hopping energy t) and the localizing efiects of the electron-electron repulsion (with strength described by TYCHO-DIMENSIONAL HUBBARD MODEL: NUMERICAL.. .
