One-particle spectral weight of the three-dimensional single-band Hubbard model.
Dynamic properties of the three-dimensional single-band Hubbard model are studied using quantum Monte Carlo combined with the maximum entropy technique. At half-filling, there is a clear gap in the density of states and well-defined quasiparticle peaks at the top ~bottom! of the lower ~upper! Hubbard band. We find an antiferromagnetically induced weight above the naive Fermi momentum. Upon hole...
متن کاملResonances for Large One-dimensional “ergodic” Systems
Abstract. The present paper is devoted to the study of resonances for one-dimensional quantum systems with a potential that is the restriction to some large box of an ergodic potential. For discrete models both on a half-line and on the whole line, we study the distributions of the resonances in the limit when the size of the box where the potential does not vanish goes to infinity. For periodi...
متن کاملResonances in one-dimensional Disordered Chain
We study the average density of resonances in a semi-infinite disordered chain coupled to a perfect lead. We concentrate on strong disorder and derive the asymptotic behavior of this density in the limit of narrow resonances.
متن کاملWell-Posedness for a One-Dimensional Fluid-Particle Interaction Model
The fluid-particle interaction model introduced by the three last authors in [J. Differential Equations, 245 (2008), pp. 3503–3544] is the object of our study. This system consists of the Burgers equation with a singular source term (term that models the interaction via a drag force with a moving point particle) and of an ODE for the particle path. The notion of entropy solution for the singula...
متن کاملA Three- Dimensional Model of the Caspian Sea
Observations of the Caspian Sea during August-September 1995 are used to develop a three-dimensional numerical model to be used in calculating temperature and current. The model has variable grid resolution and horizontal smoothing that filters out small scale vertical motion. Data from the meteorological buoy network on the Caspian Sea are combined with routine observations at first-order syno...
