Quasi-particles and their absence in photoemission spectroscopy (American Physical Society 2002 Isakson Prize Paper written for Solid State Communications, the supporter of the prize)

The elucidation of Landau Fermi liquid quasi-particles and their absence in strongly correlated electron systems lies at the heart of modern research on the quantum mechanics of electrons in

Threshold Switching and Self-Oscillation in Niobium Oxide

Volatile threshold switching, or current controlled negative differential resistance (CC-NDR), has been observed in a range of transition metal oxides. Threshold switching devices exhibit a large

Non-Linear Canonical Methods in Strongly Correlated Electron Systems

In this thesis some new ideas to perform the analysis of Strongly Correlated Electronic Systems (SCES) are developed. In particular the use of non-linear canonical transformations is considered

Variational description of the ground state of the repulsive two-dimensional Hubbard model in terms of nonorthogonal symmetry-projected Slater determinants

The few determinant (FED) methodology, introduced in our previous works for 1D lattices, is here adapted for the repulsive two-dimensional Hubbard model at half-filling and with finite doping

Ju l 2 01 4 Properties of an almost localized Fermi liquid in applied magnetic field revisited : Statistically consistent Gutzwiller approach

We discuss the Hubbard model in an applied magnetic field and analyze the properties of neutral spin1 2 fermions within the so-called statistically consistent Gutzwiller approximation (SGA). The

O líquido de spin isolante no modelo de Hubbard bidimensional levemente dopado

Our main goal here is to analyze the low-energy properties of the two-dimensional (2d) Hubbard model slightly away from half-filling from a renormalization group point of view within the two-loop

Dynamics in the one-dimensional extended ionic Hubbard model

The results for dynamical charge and spin structure factors indicate that only one of two bound/antibound state modes can be probed by electron-energy-loss spectroscopy and inelastic neutron scattering experiments.

Incommensurate charge correlation and phase diagram of the one-dimensional superlattice Hubbard model at half-filling

In the gapless region, the correlation functions exhibit the asymptotic behavior of power-law decay as in the Tomonaga-Luttinger liquid.

Metal-Insulator Transitions at Surfaces

Various types of metal-insulator transitions are discussed to find conditions for which an ideal surface of a bulk insulator is metallic. It is argued that for the correlation-driven Mott
