Fourier-Legendre expansion of the one-electron density-matrix of ground-state two-electron atoms
Sebastien Ragot, Maria Belen Ruiz
The density-matrix rho(r, r') of a spherically symmetric system can be expanded as a Fourier-Legendre series of Legendre polynomials Pl(cos(theta) = r.r'/rr'). Application is here…

Low temperature and high pressure Raman and x-ray studies of pyrochlore TbTiO : phonon anomalies and possible phase transition
Surajit Saha, D. V. S Muthu, Surjeet Singh +8
We have carried out temperature and pressure-dependent Raman and x-ray measurements on single crystals of TbTiO. We attribute the observed anomalous temperature depende…

Spin-lattice coupling in multiferroic Pb(Fe1/2Nb1/2)O3 thin films
W. Peng, N. Lemée, M. Karkut +7
We have made magnetization and x-ray diffraction measurements on an epitaxial Pb(Fe1/2Nb1/2)O3 200 nm film. From the temperature dependence of the out-of-plane lattice parameter we…
