Recent advances on ferromagnetic superconductors, UGe 2, URhGe and UCoGe are
presented. The superconductivity (SC) peacefully coexists with the ferromagnetism (FM) …

La découverte cette dernière décade de trois supraconducteurs ferromagnétiques (UGe 2,
URhGe, UCoGe) a permis de réaliser des études sur deux états principaux de la matière …

Resistivity and magnetostriction measurements were performed at high magnetic fields and
under pressure on UCoAl. At ambient pressure, the 1st order metamagnetic transition at H …

The Lifshitz transition, a change in Fermi surface topology, is likely to greatly influence exotic
correlated phenomena in solids, such as high-temperature superconductivity and complex …

The emergence of superconductivity at high magnetic fields in URhGe is regarded as a
paradigm for new state formation approaching a quantum critical point. Until now, a …

We report on Hall resistivity and electrical resistivity measurements under pressure and
magnetic field in UGe 2 with ferromagnetic (FM) tricriticality. The Hall resistivity sensitively …

Using large-scale dynamical cluster quantum Monte Carlo simulations, we study the Lifshitz
transition of the two-dimensional Hubbard model with next-nearest-neighbor hopping (t′) …

Precise band-filling control is performed on a strongly correlated electron system Na x CoO
2, by changing the Na content, and the influence of this on the magnetic and thermodynamic …

Resolving low-energy features in the density of states (DOS) holds the key to understanding
a wide variety of rich novel phenomena in graphene-based 2D heterostructures. The Lifshitz …

A ferromagnetic quantum critical point is thought not to exist in two-and three-dimensional
metallic systems yet is realized in the Kondo lattice compound YbNi 4 (P, As) 2, possibly due …
