Surface phase transitions in one-dimensional channels arranged in a triangular cross-sectional structure: Theory and Monte Carlo simulations
(American Institute of Physics, 2006-12)
Monte Carlo simulations and finite-size scaling analysis have been carried out to study the critical behavior in a submonolayer lattice-gas of interacting monomers adsorbed on one-dimensional channels arranged in a triangular ...
Infrared phonon spectrum of the tetragonal helimagnet Ba2CuGe2O7
(American Physical Society, 2014-07)
The lattice dynamics of Ba2CuGe2O7, a compound which develops Dzyaloshinsky-Moriya helical magnetism below TN=3.2 K, has been studied by measuring the infrared reflectivity of a single crystal with the radiation polarized ...
Resonance switching in a large sonic crystal cavity
(Elsevier, 2017-01)
In this work we present an experimental realization of resonance switching inside a large, relative to the lattice constant, sonic crystal (SC) cavity. The resonances arise from a temporary trapping of the acoustical energy ...
Short-term efficiency of epibenthic microbial mat components on phosphorus sorption
(Pergamon-Elsevier Science Ltd, 2020-08-03)
Microbial mats may be an alternative tool for phosphorus (P) remediation of eutrophic coastal waters. The main objective of this work was to determine the importance that the living and non-living components of the mats ...
Adsorption in one-dimensional channels arranged in a triangular structure: Theory and Monte Carlo simulations
(Elsevier Science, 2007-11)
Adsorption thermodynamics of interacting particles adsorbed on one-dimensional channels arranged in a triangular cross-sectional structure is studied through Bragg-Williams approximation (BWA), Monte Carlo (MC) simulations ...
LDA or GGA? A combined experimental inelastic neutron scattering and ab initio lattice dynamics study of alkali metal hydrides
(Elsevier Science, 2005-10)
In a previous work, we carried out inelastic neutron scattering (INS) spectroscopy experiments and preliminary first principles calculations on alkali metal hydrides. The complete series of alkali metal hydrides, LiH, NaH, ...
Finite photonic lattices: a solution using characteristic polynomials
(Revista Mexicana de Física, 2011)
Two-dimensional Ising model with Einstein site phonons
(American Physical Society, 2019-04-23)
We consider a simple Ising magnetic model in two dimensions with Einstein site phonons and study it using Monte Carlo simulations that take into account both degrees of freedom simultaneously. In nonfrustrated systems, ...
