Evidence for Dynamic Phase Separation and High Energy Spin Dynamics in underdoped La$_{2-x}$Sr$_x$CuO$_4$ from Resonant Inelastic X-Ray Scattering (2009)

Braicovich, L., Brink, J. Van Den, Bisogni, V., Sala, M. Moretti, Ament, L. J. P., Brookes, N. B., ...

We probe the collective magnetic modes of La$_2$CuO$_4$ (LCO) and underdoped La$_{2-x}$Sr$_x$CuO$_4$ (LSCO) by momentum resolved Resonant Inelastic X-ray Scattering (RIXS) at the Cu $L_3$ edge. In...

Theory of Raman and Resonant Inelastic X-ray Scattering from Collective Orbital Excitations in YTiO$_3$ (2009)

Ament, L. J. P., Khaliullin, G.

We present a theory for Raman scattering and Resonant Inelastic X-ray Scattering (RIXS) in the low temperature ferromagnetic phase of YTiO$_3$ and compare this to the available experimental data. For...

Momentum dependence of orbital excitations in Mott-insulating titanates (2009)

Ulrich, C., Ament, L. J. P., Ghiringhelli, G., Braicovich, L., Sala, M. Moretti, Pezzotta, N., ...

High-resolution resonant inelastic x-ray scattering has been used to determine the momentum dependence of orbital excitations in Mott-insulating LaTiO$_3$ and YTiO$_3$ over a wide range of the...

Resonant X-rays at the Cu L-edge as a momentum dependent probe of the magnetic excitation spectrum in cuprates (2009)

Ament, L. J. P., Ghiringhelli, G., Sala, M. Moretti, Braicovich, L., Brink, J. Van Den

We show that, contrary to common lore, in resonant inelastic x-ray scattering (RIXS) at the copper L- and M-edge direct spin-flip scattering is in principle allowed. We demonstrate how this...

Dispersing bimagnons and doping induced bimagnon-charge modes in superconducting cuprates (2008)

Braicovich, L., Ament, L. J. P., Bisogni, V., Forte, F., Aruta, C., Balestrino, G., ...

In the early days of high temperature superconductivity it was already recognized that magnetic properties of these materials are intimately related to the superconducting ones . When doped, the...

Deterministic quantum state transfer from an electronic charge qubit to a photonic polarization qubit (2006)

Ament, L. J. P., Beenakker, C. W. J.

Building on an earlier proposal for the production of polarization-entangled microwaves by means of intraband transitions in a pair of quantum dots, we show how this device can be used to transfer an...
