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…
Effect of vortices on the spin-flip lifetime of atoms in superconducting atom-chips
Gilles Nogues, Cédric Roux, Thomas Nirrengarten +7
We study theoretically the lifetime of magnetically trapped atoms in the close vicinity of a type-II superconducting surface, in the context of superconducting atom-chips. We accou…
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…
Effect of aging on the reinforcement efficiency of carbon nanotubes in epoxy matrix
Aïssa Allaoui, Pierre Evesque, Jinbo Bai
The reinforcement efficiency of carbon nanotubes (CNTs) in epoxy matrix was investigated in the elastic regime. Cyclic uniaxial tensile tests were performed at constant strain ampl…
