Can dd excitations mediate pairing?

Francesco Barantani, Christophe Berthod

The Cu-3d states in the high-T-c cuprates are often described as a single band of 3d(x2-y2) states, with the other four 3d states having about 2 to 3 eV higher energy due to the lower-than-octahedral crystal field at the copper sites. However, excitations ...

Standalone GPS L1 C/A Receiver for Lunar Missions

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Paul David Blunt, Jia Tian, Yanguang Wang

Global Navigation Satellite Systems (GNSSs) were originally introduced to provide positioning and timing services for terrestrial Earth users. However, space users increasingly rely on GNSS for spacecraft navigation and other science applications at severa ...

Spin and orbital disordering by hole doping in Pr1-xCaxVO3

Philip Pattison

High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0

Spin-resolved photoemission study of epitaxially grown MoSe2 and WSe2 thin films

Yi Zhang, Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

Few-layer thick MoSe2 and WSe2 possess non-trivial spin textures with sizable spin splitting due to the inversion symmetry breaking embedded in the crystal structure and strong spin-orbit coupling. We report a spin-resolved photoemission study of MoSe2 and ...

Orbital textures and charge density waves in transition metal dichalcogenides

Helmuth Berger

Low-dimensional electron systems, as realized in layered materials, often tend to spontaneously break the symmetry of the underlying nuclear lattice by forming so-called density waves(1); a state of matter that at present attracts enormous attention(2-6). ...

The CORALIE survey for southern extrasolar planets XVII. New and updated long period and massive planets

Malte Tewes

Context. Since 1998, a planet-search program around main sequence stars within 50 pc in the southern hemisphere has been carried out with the CORALIE echelle spectrograph at La Silla Observatory. Aims. With an observing time span of more than 14 years, the ...

Dimer phases in quantum antiferromagnets with orbital degeneracy

Dmitri Ivanov

We study and solve the ground-state problem of a microscopic model for a family of orbitally degenerate quantum magnets. The orbital degrees of freedom are assumed to have a directional character and are represented by static Potts-like variables. In the l ...
