Resonant Inelastic X-Ray Scattering Study of Electron-Exciton Coupling in High-T-c Cuprates

Christophe Berthod, Fabrizio Carbone, Ivan Madan, Yi Tseng, Francesco Barantani, Thorsten Schmitt, Dirk Van der Marel

Explaining the mechanism of superconductivity in the high-T-c cuprates requires an understanding of what causes electrons to form Cooper pairs. Pairing can be mediated by phonons, the screened Coulomb force, spin or charge fluctuations, excitons, or by a c ...

Melting of a skyrmion lattice to a skyrmion liquid via a hexatic phase

Marco Cantoni, Arnaud Magrez, Henrik Moodysson Rønnow, Fabrizio Carbone, Ping Huang, Thomas Schönenberger

While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...
