Large polarons as key quasiparticles in SrTiO3 and SrTiO3-based heterostructures
Andrey Geondzhian, Alessia Sambri, Gabriella M. De Luca +11
Despite its simple structure and low degree of electronic correlation, SrTiO (STO) features collective phenomena linked to charge transport and, ultimately, superconductivity,…
Dispersive charge density wave excitations and temperature dependent commensuration in Bi2Sr2CaCu2O8+δ
Laura Chaix, Giacomo Ghiringhelli, Yingying Peng +14
Experimental evidence on high-Tc cuprates reveals ubiquitous charge density wave (CDW) modulations, which coexist with superconductivity. Although the CDW had been predicted by the…
The Conducting Channel at the LaAlO/SrTiO Interface
Z. Huang, X. Renshaw Wang, Z. Q. Liu +10
Localization of electrons in the two-dimensional electron gas at the LaAlO/SrTiO interface is investigated by varying the channel thickness in order to establish the nature…
Origin of interface magnetism in BiMnO3/SrTiO3 and LaAlO3/SrTiO3 heterostructures
M. Salluzzo, S. Gariglio, D. Stornaiuolo +11
Possible ferromagnetism induced in otherwise non-magnetic materials has been motivating intense research in complex oxide heterostructures. Here we show that a confined magnetism i…
Long-range incommensurate charge fluctuations in (Y,Nd)Ba2Cu3O(6+x)
G. Ghiringhelli, M. Le Tacon, M. Minola +17
There are increasing indications that superconductivity competes with other orders in cuprate superconductors, but obtaining direct evidence with bulk-sensitive probes is challengi…
Dispersing bimagnons and doping induced bimagnon-charge modes in superconducting cuprates
L. Braicovich, L. J. P. Ament, V. Bisogni +11
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 . W…
