Eigenvalues from power--series expansions: an alternative approach
P. Amore, F. M. Fernandez
An appropriate rational approximation to the eigenfunction of the Schrödinger equation for anharmonic oscillators enables one to obtain the eigenvalue accurately as the limit of a…
Ballistic deposition on deterministic fractals: On the observation of discrete scale invariance
Claudio M. Horowitz, Federico Roma, Ezequiel V. Albano
The growth of ballistic aggregates on deterministic fractal substrates is studied by means of numerical simulations. First, we attempt the description of the evolving interface of…
Non-equilibrium Characterization of Spinodal Points using Short Time Dynamics
Ernesto S. Loscar, Ezequiel E. Ferrero, Tomas S. Grigera +1
Though intuitively appealing, the concept of spinodal is rigourously defined only in systems with infinite range interactions (mean field systems). In short-range systems, a pseudo…
Born-Oppenheimer approximation for a harmonic molecule
Francisco M. Fernández
We apply the Born--Oppenheimer approximation to a harmonic diatomic molecule with one electron. We compare the exact and approximate results not only for the internal degrees of fr…
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…
On nonadiabatic calculation of dipole moments
Francisco M. Fernandez
We show that a recent non Born--Oppenheimer calculation of dipole moments exhibits obscure points and is not consistent with the well known Hellmann--Feynman theorem.
From Capillary Condensation to Interface Localization Transitions in Colloid Polymer Mixtures Confined in Thin Film Geometry
Andres De Virgiliis, Richard L. C. Vink, Jürgen Horbach +1
Monte Carlo simulations of the Asakura-Oosawa (AO) model for colloid-polymer mixtures confined between two parallel repulsive structureless walls are presented and analyzed in the…
Rayleigh-Ritz variation method and connected-moments polynomial approach
Francisco M. Fernandez
We show that the connected-moments polynomial approach proposed recently is equivalent to the well known Rayleigh-Ritz variation method in the Krylov space. We compare the latter w…
The Magnetic Eden Model
Julián Candia, Ezequiel V. Albano
In the magnetic Eden model (MEM), particles have a spin and grow in contact with a thermal bath. Although Ising-like interactions affect the growth dynamics, deposited spins are fr…
Thermodynamic signature of growing amorphous order in glass-forming liquids
G. Biroli, J. -P. Bouchaud, A. Cavagna +2
Although several theories relate the steep slowdown of glass formers to increasing spatial correlations of some sort, standard static correlation functions show no evidence for thi…
Accurate eigenvalues of bounded oscillators
Francisco M. Fernandez
We calculate accurate eigenvalues of a bounded oscillator by means of the Riccati--Padé method that is based on a rational approximation to a regularized logarithmic derivative of…
From particles to spins: Eulerian formulation of supercooled liquids and glasses
Claudio Chamon, Leticia F. Cugliandolo, Gabriel Fabricius +2
The dynamics of supercooled liquid and glassy systems are usually studied within the Lagrangian representation, in which the positions and velocities of distinguishable interacting…
