Ubiquitous Interplay between Charge Ordering and High-Temperature Superconductivity in Cuprates
Eduardo H. da Silva Neto, Pegor Aynajian, Alex Frano +11
Besides superconductivity, copper-oxide high temperature superconductors are susceptible to other types of ordering. We use scanning tunneling microscopy and resonant elastic x-ray…
Lattice dynamical signature of charge density wave formation in underdoped YBa2Cu3O6+x
M. Bakr, S. M. Souliou, S. Blanco-Canosa +10
We report a detailed Raman scattering study of the lattice dynamics in detwinned single crystals of the underdoped high temperature superconductor YBa2Cu3O6+x (x=0.75, 0.6, 0.55 an…
Optically enhanced coherent transport in YBa2Cu3O6.5 by ultrafast redistribution of interlayer coupling
W. Hu, S. Kaiser, D. Nicoletti +7
Nonlinear optical excitation of infrared active lattice vibrations has been shown to melt magnetic or orbital orders and to transform insulators into metals. In cuprates, this tech…
Comparison of charge modulations in LaBaCuO and YBaCuO
V. Thampy, S. Blanco-Canosa, M. García-Fernández +7
A charge modulation has recently been reported in (Y,Nd)BaCuO [Ghiringhelli {\em et al.} Science 337, 821 (2013)]. Here we report Cu edge soft x-ray scatterin…
Magnetic excitations in stripe-ordered LaBaCuO studied using resonant inelastic x-ray scattering
M. P. M. Dean, G. Dellea, M. Minola +10
The charge and spin correlations in LaBaCuO (LBCO 1/8) are studied using Cu edge resonant inelastic x-ray scattering (RIXS). The static charge order (…
Anharmonicity due to Electron-Phonon Coupling in Magnetite
Moritz Hoesch, Przemyslaw Piekarz, Alexey Bosak +5
We present the results of inelastic x-ray scattering for magnetite and analyze the energies and spectral widths of the phonon modes with different symmetries in a broad range of te…
Dispersive spin excitations in highly overdoped cuprates revealed by resonant inelastic x-ray scattering
M. Le Tacon, M. Minola, D. C. Peets +11
Using resonant inelastic x-ray scattering (RIXS) at the Cu -absorption edge, we have observed intense, dispersive spin excitations in highly overdoped TlBaCuO (s…
