This is a series of 4 papers on the different behaviour between electrons and holes in solid state physics:
1) http://arxiv.org/abs/0901.3612;

Contents:introduction; quantum monte carlo methods; nodal properties of fermionic wave functions; Pfaffian pairing wave functions; Backflow correlations in slater and pfaffian wave functions; example . . . . .

These are introductory lectures to some aspects of the physics of strongly correlated electron systems. I first explain the main reasons for strong correlations in several classes of materials. The ba . . . . .

In this paper, they describe the combined approach of Car and Parrinello to determine the simultaneous “on-the-fly” evolution of the (Newtonian) nuclear degrees of freedom and of the electronic wavef . . . . .

The first dwarf galaxies, which constitute the building blocks of the collapsed objects we find today in the Universe, had formed hundreds of millions of years after the big bang. This pedagogical rev . . . . .

We discuss our current understanding of the interior structure and thermal evolution of giant planets. This includes the gas giants, such as Jupiter and Saturn, that are primarily composed of hydrogen . . . . .
