Unusual upper critical field in UTe2 revealed by magnetotransport measurements up to 42 T
Macha Méplan, Ilya Sheikin, Pierre Pugnat +16
The heavy-fermion superconductor UTe2 is unique in that, at ambient pressure, it exhibits three distinct superconducting phases, two of which are induced by magnetic field. When th…
Fermi-liquid versus non-Fermi-liquid/'strange-metal' fits to the electrical resistivity in the quantum critical magnetic regime of an unconventional superconductor
W. Knafo, T. Thebault, K. Somesh +4
The question of a possible quantum critical point lying inside of a superconducting phase is central for understanding unconventional superconductivity. In various unconventional s…
Bridging atomic and mesoscopic length scales with Replica Scanning Tunneling Microscopy: Visualizing the atomic lattice of UTe and the atomic scale superconducting gap modulations of FeSe close to micron length scales
Miguel Ãgueda Velasco, Miguel Águeda Velasco, Jose D. Bermúdez-Pérez +21
Scanning Tunneling Microscopy is a cornerstone technique for visualizing the electronic density of states with atomic resolution (typically below 0.1 nm). While the field of view o…
Surface charge density wave in UTe2
Pablo GarcÃa Talavera, Pablo García Talavera, Miguel Ãgueda Velasco +16
The spatially uniform electronic density characteristic of a metal can become unstable at low temperatures, leading to the formation of charge density waves (CDWs). These CDWs, obs…
Metastability of the Topological Magnetic Orders in the Chiral Antiferromagnet EuPtSi
Simon Rousseau, Gabriel Seyfarth, Georg Knebel +3
We report resistivity and Hall effect measurements in the chiral antiferromagnet EuPtSi. Depending on the magnetic field orientation with respect to the crystallographic axes, EuPt…
