Soft Modes and Relaxor Ferroelectrics

R. A. Cowley, S. N. Gvasaliya, B. Roessli

Relaxor ferroelectrics are difficult to study and understand. The experiment shows that at low energy scattering there is an acoustic mode, an optic mode, dynamic quasi-elastic sca…

Noncentrosymmetric Commensurate Magnetic Ordering of Multiferroic ErMn2O5

B. Roessli, P. Fischer, P. J. Brown +7

The non-centrosymmetric magnetic structure of ErMnO has been shown to be very similar to that of HoMnO (Vecchini {\it et al.}, 2008 Phys. Rev. B {\bf 77} 134434). T…

X-ray study of structural domains in the near-surface region of SrTiO3-substrates with Y0.6Pr0.4Ba2Cu3O7$ / La2/3Ca1/3MnO3 superlattices grown on top

J. Hoppler, J. Stahn, H. Bouyanfif +6

We investigated with synchrotron x-ray diffraction and reflectometry the formation of structural domains in the near-surface region of single crystalline SrTiO3 (001) substrates wi…

An efficient and accurate decomposition of the Fermi operator

Michele Ceriotti, Thomas Kuehne, Michele Parrinello

We present a method to compute the Fermi function of the Hamiltonian for a system of independent fermions, based on an exact decomposition of the grand-canonical potential. This sc…

Effect of Inversion Symmetry on Incommensurate Order in Multiferroic RMn2O5, R=rare earth

A. B. Harris, M. Kenzelmann, Amnon Aharony +1

Starting from the irreducible representations of the group of the wave vector we construct the spin wave functions consistent with inversion symmetry, neglected in the usual repres…

Dressed excitonic states and quantum interference in a three-level quantum dot ladder system

B. D. Gerardot, D. Brunner, P. A. Dalgarno +4

We observe dressed states and quantum interference effects in a strongly driven three-level quantum dot ladder system. The effect of a strong coupling field on one dipole transitio…
