Structure and Raman Spectra in Cryolitic Melts: Simulations with an ab Initio Interaction Potential
(Amer Chemical Soc, 2014)
The Raman spectra of cryolitic melts have been calculated from molecular dynamics computer simulations using a polarizable ionic potential obtained by force-fitting to ab initio electronic structure calculations. Simulations ...
Condensation of two-dimensional harmonically confined bosons with Bessel-type interactions
(Amer Physical Soc, 2011)
We study the ground-state configurations of few interacting bosons confined in two dimensions by anisotropic harmonic potentials. By means of variational calculations, including correlation effects, we show that the ...
Localization-delocalization transition in the random dimer model
(Amer Physical Soc, 2010)
The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ...
Dynamical instability of a boson-fermion mixture at low dimensions
(Elsevier Science Bv, 2009)
We examine theoretically the dynamical response of a homogeneous mixture of condensed bosons and spin-polarized fermions confined inside a quasi-two-dimensional or a quasi-one-dimensional geometry, considering quasi-thre ...
Condensate oscillations oscillations in a Penrose tiling lattice
(Elsevier Science Bv, 2017)
We study the dynamics of a Bose-Einstein condensate subject to a particular Penrose tiling lattice. In such a lattice, the potential energy at each site depends on the neighbour sites, accordingly to.the model introduced ...
Anderson localization in optical lattices with speckle disorder
(Amer Physical Soc, 2011)
We study the localization properties of noninteracting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a combined decimation-renormalization procedure, we estimate the localization ...
Investigation of vibrational, elastic and dielectric properties of cubic gauche nitrogen (cg-N)
(Elsevier GmbH, 2021)
Vibrational, elastic and dielectric properties of the cubic gauche nitrogen (cg-N) are investigated by analyzing the Raman optic and zone-center phonon modes using the literature data. From the pressure dependence of those ...
