Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Thermonuclear fusion of light atoms is considered since decades as an unlimited, safe and reliable source of energy that could eventually replace classical sources based on fossile fuel or nuclear fuel. Fusion reactor technology and materials studies are i ...
ICON is the new cold neutron imaging facility at the neutron spallation source SINQ. The ICON facility is placed at beam-line S52 with direct view to the cold liquid D-2 moderator. The beam-line includes a 4.4 m long collimation section followed by a 1 I m ...
We will review recent results obtained by longitudinal polarization analysis (LPA) and spherical neutron polarimetry (SNP) on typical "low-dimensional" strongly correlated electronic systems (spin-Peierls CuGeO3, High-T-c YBa2Cu3O6+x...), which all demonst ...
We will review recent results obtained by longitudinal polarization analysis and spherical neutron polarimetry (SNP) on typical low-dimensional strongly correlated electronic systems (spin-Peierls CuGeo(3), high-T-c La0.85Sr0.15CuO4 and YBa2CU3O6+x, or spi ...
The longitudinal low frequency acoustic and optic phonon modes of 2H-NbSe2 have been determined for the Gamma - M direction with inelastic neutron scattering at 50 K close to the charge density wave transition temperature. ...
The compound BaCuSi2O6 is a quantum magnet with antiferromagnetic dimers of S=1/2 moments on a quasi-2D square lattice. We have investigated its spin dynamics by inelastic neutron scattering experiments on single crystals with an energy resolution consider ...
CuGeO3 is a good realization of a spin-Peierls system. Using neutron scattering, we have investigated the transition from the dimerized spin-Peierls phase to an incommensurately modulated high-field phase. The incommensurate period has been measured for fi ...
Using a first-principles approach, we study the vibrational properties of vitreous SiO2 which are measured in neutron-scattering experiments. We adopt a model structure consisting of corner-sharing tetrahedra, which was previously generated using first-pri ...
Small angle neutron scattering experiments have been undertaken on the tempered martensitic steel EUROFER97 after proton irradiation at 250 and 350 degreesC and for doses of 0.3 and 1 dpa. It has been qualitatively shown that the scattering arises from dis ...
The magnetic resonance at 41 meV observed in neutron scattering studies of YBa2Cu3O7 holds a key position in the understanding of high-T-c, superconductivity. Within the SO(5) model for superconductivity and antiferromagnetism, we have calculated the effec ...
