Quantum Simulation of the Hubbard Model: The Attractive Route
A. F. Ho, M. A. Cazalilla, T. Giamarchi
We study the conditions under which, using a canonical transformation, the phases sought after for the repulsive Hubbard model, namely a Mott insulator in the paramagnetic and anti…
On the density of states and extinction mean free path of waves in random media: Dispersion relations and sum rules
R. Carminati, M. Donaire, J. J. Saenz
We establish a fundamental relationship between the averaged density of states and the extinction mean free path of wave propagating in random media. From the principle of causalit…
Energy loss of charged particles moving parallel to a magnesium surface
M. G. Vergniory, V. M. Silkin, I. G. Gurtubay +1
We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band st…
Dynamic Arrest in Polymer Melts: Competition between Packing and Intramolecular Barriers
Marco Bernabei, Angel J. Moreno, Juan Colmenero
We present molecular dynamics simulations of a simple model for polymer melts with intramolecular barriers. We investigate structural relaxation as a function of the barrier streng…
Tight--binding description of the quasiparticle dispersion of graphite and few--layer graphene
A. Grüneis, C. Attaccalite, L. Wirtz +3
A universal set of third--nearest neighbour tight--binding (TB) parameters is presented for calculation of the quasiparticle (QP) dispersion of stacked graphene layers (…
Exact-exchange Kohn-Sham potential, surface energy, and work function of jellium slabs
C. M. Horowitz, C. R. Proetto, J. M. Pitarke
Exact-exchange self-consistent calculations of the Kohn-Sham potential, surface energy, and work function of jellium slabs are reported in the framework of the Optimized Effective…
