On the high-density expansion for Euclidean Random Matrices
T. S. Grigera, V. Martin-Mayor, G. Parisi +2
Diagrammatic techniques to compute perturbatively the spectral properties of Euclidean Random Matrices in the high-density regime are introduced and discussed in detail. Such techn…
Further analysis of the connected moments expansion
Paolo Amore, Francisco M. Fernández, Martin Rodriguez
We apply the connected moments expansion to simple quantum--mechanical examples and show that under some conditions the main equations of the approach are no longer valid. In parti…
High--order connected moments expansion for the Rabi Hamiltonian
Paolo Amore, Francisco M. Fernández, Martin Rodriguez
We analyze the convergence properties of the connected moments expansion (CMX) for the Rabi Hamiltonian. To this end we calculate the moments and connected moments of the Hamiltoni…
Unconventional magnetization processes and thermal runaway in spin-ice DyTiO
D. Slobinsky, C. Castelnovo, R. A. Borzi +4
We investigate the non-equilibrium behavior of the spin-ice material DyTiO by studying its magnetization as a function of the rate at which an external field is swept.…
Variational and perturbative approaches to the confined hydrogen atom with a moving nucleus
Francisco M. Fernández, N. Aquino, A. Flores-Riveros
We calculate the ground--state energy and other physical properties of the hydrogen atom inside a spherical box with an impenetrable wall. We apply the variational method and pertu…
Numerical simulations of liquids with amorphous boundary conditions
A. Cavanga, T. S. Grigera, P. Verrocchio
It has recently become clear that simulations under amorphpous boundary conditions (ABCs) can provide valuable information on the dynamics and thermodynamics of disordered systems…
Dynamic relaxation of a liquid cavity under amorphous boundary conditions
Andrea Cavagna, Tomas S. Grigera, Paolo Verrocchio
The growth of cooperatively rearranging regions was invoked long ago by Adam and Gibbs to explain the slowing down of glass-forming liquids. The lack of knowledge about the nature…
Short-Time Critical Dynamics of Damage Spreading in the Two-Dimensional Ising Model
M. Leticia Rubio Puzzo, Ezequiel V. Albano
The short-time critical dynamics of propagation of damage in the Ising ferromagnet in two dimensions is studied by means of Monte Carlo simulations. Starting with equilibrium confi…
Perturbation theory for confined systems
Francisco M. Fernández
We discuss the application of perturbation theory to a system of particles confined in a spherical box. A simple argument shows that the particles behave almost independently in su…
Simple one-dimensional quantum-mechanical model for a particle attached to a surface
Francisco M. Fernández
We present a simple one-dimensional quantum-mechanical model for a particle attached to a surface. We solve the Schrödinger equation in terms of Weber functions and discuss the beh…
Localized versus extended systems in density-functional theory: some lessons from the Kohn-Sham exact exchange potential
C. M. Horowitz, C. R. Proetto, J. M. Pitarke
A long-standing puzzle in density-functional theory is the issue of the long-range behavior of the Kohn-Sham exchange-correlation potential at metal surfaces. As an important step…
A phase-separation perspective on dynamic heterogeneities in glass-forming liquids
C. Cammarota, A. Cavagna, I. Giardina +4
We study dynamic heterogeneities in a model glass-former whose overlap with a reference configuration is constrained to a fixed value. The system phase-separates into regions of sm…
Comment on `Effective polar potential in the central force Schrödinger equation'
Francisco M. Fernández
We analyze a recent pedagogical proposal for an alternative treatment of the angular part of the Schrödinger equation with a central potential. We show that the authors' arguments…
