The Interplay Between Structural and Electronic Degrees of Freedom in Superconductors

Mathieu Julien Gino Cottet

More than one hundred years after the discovery of superconductivity in Leiden, the intriguing physics of several unconventional classes of superconductors continue to fascinate and challenge scientists from all over the world. The majority of these compou ...

Evidence for a Peierls phase-transition in a three-dimensional multiple charge-density waves solid

Majed Chergui, Fabrizio Carbone, Thomas James Penfold, Mathieu Julien Gino Cottet

The effect of dimensionality on materials properties has become strikingly evident with the recent discovery of graphene. Charge ordering phenomena can be induced in one dimension by periodic distortions of a material's crystal structure, termed Peierls or ...

Quantitative imaging of flux vortices in the type-II superconductor MgB2 using cryo-Lorentz transmission electron microscopy

Cécile Hébert, Marco Cantoni, Fabrizio Carbone, Duncan Thomas Lindsay Alexander, Mathieu Julien Gino Cottet

Imaging of flux vortices in high quality MgB2 single crystals has been successfully performed in a commercial field-emission gun-based transmission electron microscope. In cryo-Lorentz microscopy, the sample quality and the vortex lattice can be monitored ...

Temperature-dependent electron-phonon coupling in La_{2−x}Sr_{x}CuO_{4} probed by femtosecond x-ray diffraction

Majed Chergui, Henrik Moodysson Rønnow, Fabrizio Carbone, Giulia Fulvia Mancini, Krunoslav Prsa, Mathieu Julien Gino Cottet

The strength of the electron-phonon coupling parameter and its evolution throughout a solid's phase diagram often determines phenomena such as superconductivity, charge- and spin-density waves. Its experimental determination relies on the ability to distin ...
