Landau free energy of ferroelectric crystals by thermodynamic integration

Gregory Geneste

Using Molecular Dynamics simulations based on the effective hamiltonian developed by Zhong, Vanderbilt and Rabe [Phys. Rev. Lett. {\bf 73}, 1861 (1994)] (and fitted on first-princi…

Phenomenological theory of phase transitions in epitaxial BaxSr(1-x)TiO3 thin films

V. B. Shirokov, Yu. I. Yuzyuk, B. Dkhil +1

A phenomenological thermodynamic theory of BaxSr(1-x)TiO3 (BST-x) thin films epitaxially grown on cubic substrates is developed using the Landau-Devonshire approach. The eighth-ord…

Temperature dependent Raman and x-ray studies of spin-ice pyrochlore and non-magnetic pyrochlore

Surajit Saha, Surjeet Singh, B. Dkhil +5

We present here temperature-dependent Raman, x-ray diffraction and specific heat studies between room temperature and 12 K on single crystals of spin-ice pyrochlore compound $Dy_2T…

Effect of high pressure on multiferroic BiFeO3

R. Haumont, P. Bouvier, A. Pashkin +6

We report experimental evidence for pressure instabilities in the model multiferroic BiFeO3 and namely reveal two structural phase transitions around 3 GPa and 10 GPa by using diff…

Comments on the momentum density and the spatial form of the density-matrix of the Hooke's atom

Ragot Sebastien

In a recent paper, A. Akbari, N. H. March and A. Rubio [Phys. Rev. A. 76, 032510 (2007)] have investigated the one-electron reduced density-matrix and the momentum density of sever…
